What is Diarrhea Due to Diet?

There are instances when your dog will suffer from bouts of loose stools or diarrhea. Generally, diarrhea will be the result of an illness but there are instances when diarrhea is caused by your dog’s diet. This can be from eating too much, eating spoiled food or eating out of the garbage. Many veterinarians call this garbage gut or garbage toxicosis. A food intolerance or allergy can also cause your dog to experience diarrhea.

Changing your dog’s diet can also cause your dog to develop diarrhea. When you change your dog’s food it can take a few days for your dog’s digestive system to fully adapt to the new protein sources. It is recommended that you slowly change your dog’s food from one source to another by mixing the two together equally and then slowly decrease the amount of the first food.

When your dog eats, the food will travel down the esophagus quickly and enter the stomach in large pieces or chunks. Their salivary enzymes are not designed to break down the food but to kill bacteria. The acids within the stomach will break down the food and disperse the nutrients and rid the body of waste in the form of well-formed stool and urine.

Symptoms of Diarrhea Due to Diet in Dogs

Obviously, when your dog is suffering from diarrhea they will have frequent bowel movements that are loose or watery. There are other symptoms to watch for that will indicate that your dog has diarrhea. Diarrhea can quickly become a concern because your dog can become dehydrated. Call your veterinarian for an appointment if you suspect your dog has diarrhea. Other symptoms of diarrhea to watch for include:

  • Anxiously needing to go outside quickly
  • Having bowel movements in the house
  • Straining
  • Stomach ache
  • Fever
  • Lethargy
  • Loss of appetite
  • Dehydration

Causes of Diarrhea Due to Diet in Dogs

Diarrhea can occur for many different reasons in dogs. Commonly it is illness that causes your dog to develop diarrhea. However, diarrhea due to diet should not be ruled out. Many times your dog will get into something that they should not have eaten and that can cause stomach upset and diarrhea. 

Changing your dog’s food can cause diarrhea if not done slowly so their digestive tract can adjust to the new food. Allowing your dog to eat too much or eating garbage can also cause diarrhea. A food allergy or intolerance will cause gastrointestinal upset and diarrhea.

Diagnosis of Diarrhea Due to Diet in Dogs

When you bring your dog to your veterinarian, a stool sample will need to be given. If you are unable to collect one, your veterinarian can do so. Your dog’s medical history will need to be given as well as a detailed list of what your dog eats or might have eaten. 

The stool sample will be used in a fecal exam to look for internal parasites. Internal parasites can cause diarrhea in dogs. A urinalysis, complete blood count and biochemistry panel will also be done to rule out certain illnesses and conditions. A hands-on physical examination will be conducted by your veterinarian. They will palpate your dog’s abdomen, check their vitals and take their temperature.

Your veterinarian will need to know how quickly the symptoms came on and if there were any changes in the environment. Once all the tests have come back and the physical examination is completed, your veterinarian will be able to diagnose your dog’s diarrhea being from their diet; either overeating, intolerance or allergy, or change in food.

Treatment of Diarrhea Due to Diet in Dogs

Many cases of chronic diarrhea will require intravenous fluid therapy to stop dehydration from occurring. This may require a stay in the animal hospital until the diarrhea is stopped and the threat of dehydration has passed. Anti-diarrhea medication may also be prescribed.

Food may need to be withheld for at least 24 hours. Small amounts of water will need to be given frequently to keep them hydrated if they are not already dehydrated. A bland diet can be given after 24 hours. If there is no more diarrhea your dog can slowly be changed back to their regular diet.

In the case of your dog having an allergy or intolerance to an ingredient in their food, their diet will need to be permanently altered to avoid the ingredient that is problematic. Your veterinarian can suggest a food that will not have the ingredient that is causing diarrhea in your dog.

Recovery of Diarrhea Due to Diet in Dogs

When your dog is diagnosed with diarrhea due to their diet, your veterinarian will discuss with you what foods are best for your dog. Once the diarrhea is stopped, you will be able to give your dog their regular food. If there is an allergy or intolerance, you will need to switch their food to one that will not cause diarrhea. 

If your dog loves to play in the garbage, secure your trash cans away from your dog to discourage him from eating the trash. Do not feed your dog leftovers from your own dinner plate. Human food can cause gastrointestinal upset and diarrhea.

Diarrhea,

Our 7 week old rottweiler puppy was on a raw food diet when we first got her and the stools were firm (amount was very little). We recently changed her diet to dry puppy kibble because I heard you shouldn't mix kibble with raw meat but she's having diarrhea (very loose stool with liquid). I don't Know if I should keep giving it to her or if I should fast her for 12 hours. And how long will the diarrhea last for?

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM

A sudden change in diet may lead to diarrhoea, you can try fasting her and then offering a boiled chicken and rice diet to see if the stool firms up; once it firms up you should start to wean across to the kibble slowly. Also, puppies may have worms or protozoan parasites which may add to the diarrhoea. Regards Dr Callum Turner DVM

My dog had a sudden bout of loose stools. I weened him from Bil-Jac to Wellness Core over the course of a few weeks. His first 10 days on just Wellness Core were fine (stool looser but not diarrhea). When I took him for his normal walk he pooped multiple times each runnier than the last. When I came home from work, he had pooped while in his crate, which he has never done. I can't find anything that he may have gotten into and haven't fed him scraps. Very concerned.

There are various causes for diarrhoea in dogs which include dietary changes, however we would normally see problems during the transition and not ten days afterwards; other possible causes include infections, parasites, stress, foreign objects, poisoning among other conditions. Keep an eye on Bob Marley and see if there is any improvement (also ensure he remains hydrated), if there is no improvement in the faecal quality or other symptoms present visit your Veterinarian.

Diarrhea

Hello, I have a 4 month old Border Collie/ McNabb mix. She's a very playful well energetic puppy with no issues other than whenever we feed her dry puppy food of any kind, it causes terrible watery diarrhea. When we first brought her home she was on dry grain free, corn free high end dog food but had the diarrhea. We took who to the vet who said she had an intentional infection not caused by worms and put her on the prescription science diet food and antibiotics for 10 days. She got better. We put her back on the dry diet food and the diarrhea instantly came back. So we finally found a canned wet dog food similar in structure to the science diet (chunks of meat not pureed meat) and she's normal. My question is this, what would cause this issue in my dog from dry dog food? Feeding a puppy wet canned food is very expensive so I'm trying to find alternatives that would help bring the costs down a bit without compromising her health. Thank you! (Also, we did try 3 types of dry kibble before putting her back on canned food. All 3 had the same outcome)

You should be looking at the different ingredients of the dogs foods and see which ingredients are present in the dog food which causes diarrhoea and which ingredients are safe in the wet food; then try to compare different kibble dogs foods to see which one may be suitable for Magic, sometimes there are no shortcuts.

A sudden change in diet especially for a young pup can cause diarrhoea which is normally self limiting after a few days or so once the gastrointestinal tract has learnt the new food and everything has calmed down. Continue to feed her, but if there is no improvement in the faecal consistency you should visit a Veterinarian to make sure that there are no parasites etc… Regards Dr Callum Turner DVM

My dog is a hound mix, 1 year+4 months, about 85 pounds.
All summer he had diarrhea and we tried all kinds of probiotics, antibtiotics, food changes, etc. We finally found that when we cut out wheat it made a big difference, and then we gave him Tylan powder and he seemed to be cured! All winter his poops were firm enough to be able to pick up easily.
Now all our snow is gone and it is getting warmer. Over the weekend he was ill - he wouldn't eat for a day and had vomiting and diarrhea and lethargy. After a day of metronidazole and fortiflora he is back to his normal self except...still diarrhea! We are back to where we were last spring.
I think it must be something he's getting into in the back yard. He scrounges and I know he is eating Bradford pears from the neighrbor's tree, and I suspect he will eat rabbit poop if he finds it and will drink from puddles, and any food-like thing that may be back there he will eat. No other plants though other than maybe maple leaves and grass. What could it be? How can we fix it??

Thank you for your email. WIthout examining Bruno, I can't comment on what might be going on with him, but from your description, it seems that it would be best to keep him from eating things in the backyard, if you know that he is eating things that are going to give him diarrhea, you can take him out on a leash, or walk him so that you know that he isn't getting into anything that he shouldn't. I hope that all goes well for him.

Resending

We didn't change his diet and that's not the cause hence we do not know the cause, he was in his usual diet as mentioned but had 1 episode of loose stool but after that he had 2 more. Now he was recommended to take 2.5ml each of vizylac and normet at 6pm that day after which he didn't have stools either That night or next day where his diet now was only curds morning and afternoon. At 6pm again we had again given his medication and around 8 pm he was asked to give half the amount of his usual food i.e royal canin 15gms but around 10:45pm he vomited once. (Want to put to your notice he has the habit to nibble into things which I feel maybe the cause). He was fine all through the night and at 8:30am i gave him curds. No vomiting and stools yet after 2 hrs of his meal. Are we doing the right thing? When do we go back with his normal diet of royal canin?

We had to abruptly change my 7 month old Dobermans food (as everywhere near me stopped selling hers and it was breaking the bank) she had only 2 meals where she was able to have them mixed and since then she has gotten purely the new food. She has been solely on the new food for 4 days now, she had been having loose stool but was holding it until she was on walks which is her normal behavior. Last night however she had very liquid diarrhea 4 times in the house through the night, these are her first accidents since she was 3 months. would her diet change be what’s affecting her this much more this far into it?

That sudden diet change may be causing her diarrhea, yes, and that can take a few days to resolve. It may also be parasites or another intestinal cause for upset. If the diarrhea continues, she may need to be seen by your veterinarian to get treatment to help stop the diarrhea.

My Bernese mountain dog was deemed overweight by our vet about 2 years ago. We went on diet food and finally went back to the vet about 1.5 years later because of bad skin and loose stool. He had lost 28 lbs (too much weight). We tried switching back to old food. It gave him worse poop/diarrhea. We tried 3-4 different types of food (including prescription) and it hasn’t helped. We’ve used chicken and rice between switching foods and while it doesn’t make him have uncontrollable diarrhea, he still has loose stool at best.

They’ve done 2-3 different fecal sample for parasites and thing and it’s all negative. We can’t seem to get him on a diet that works and the next steps the vet is talking about are $300-700 each. Different types of checks and an ultrasound. We can’t afford it. We don’t know what else to do. He doesn’t show any signs of cancer (other than diarrhea). No real tiredness, blood in stool or anything like that.

Sudden dietary changes may cause diarrhoea, however this is generally self limiting and resolved when the dog’s gastrointestinal tract adjusts to the food; there are many other causes for diarrhoea in dogs which may include infections, parasites, poisoning, foreign objects, stress among other causes. Further investigation is needed to narrow in on a specific cause, an ultrasound would be useful to look for any pathological changes but it is difficult to weight in without examining Kingsley first.

So puppy would have diarrhea then a solid stool but then back to a non solid form. We had to change the his food brand because the owners before didn't give us what he was eating. He has been two dosages for parasites he has no other symptoms he plays a lot, eats, drinks a lot of water, have tried to control the amount he eats which before he would eat a lot. Also when the owners gave him to us his poop was normal. Went to vet got medication to control it and it was fine until we stop using it. It's started the 3rd day we got him and after not using the medicine his second stool of the day came out non formed. Is it the diet, parasites, or an intestinal thing?ps. Up-to-date on puppy shots.

I'm not sure what parasites Thor was diagnosed with, but some parasites can take a while to recover from. He may need further medications, or probiotics, or a GI diet. Since he has recently been seen by your veterinarian, it would be a good idea to call them and let them know that his diarrhea is continuing and see what they recommend, as they know more about his health status and history than i do. I hope that all goes well for him.

Hi, my dog has been on science diet wet food his whole life. I decided I wanted to switch him to Annamaet kibble and chose one that was the close to his current diet. I switched him completely within a week however as soon as I gave him a full days worth of the kibble he started having liquid diarrhea. I stopped the kibble and started him on rice. Then he began throwing up so I withheld food for 12 hours. I started him back on the rice and he didn’t poop for 24 hours so I then started mixing the rice with his original wet food and he finally pooped but it’s still not a normal poop, very soft but not liquid. Should I keep up with the rice mixed with wet another day?

It may take a little time for Bean’s stomach to calm down, continue with the current diet until you see a better consistency of faeces; afterwards you can continue to wean Bean over to either the new diet over a long period of time or the old diet. If you are having difficulty, try to move over to a boiled chicken and rice diet for a few days and then introduce the food; if still no improvement visit your Veterinarian.

You should also check in with your Veterinarian and have a stool sample checked for parasites to cover all bases. Regards Dr Callum Turner DVM

Boiled chicken breast seems to be the diarrhea-proof food to feed your dog but I have this suspicion that's not the case with my dog. It's not diarrhea but one or two steps next to it. Semi-melted ice-cream formed like a stool? I thought it was the kibble I fed her in the morning but I've recently done a kibble-only diet and now her poo is great. If chicken breast isn't the issue then the only thing I can think of is that I cut it up too finely and she eats it too quickly. She basically inhales it. What do you think?

If Baby is having normal stool with kibbles alone, you should stick with just the kibbles as long as they are a complete diet suitable for breed and age; when a complete diet is fed you don’t need to think about supplementing with anything else. Boiled chicken breast and rice (33%:67%) is an ideal bland non-irritating food which we use when a dog keeps vomiting up food or is recovering from an issue affecting the stomach; but in this instance I would stick 100% with kibbles.

My dog has been starting to have diarrhea. We didn’t ever look to see how much she should be feeding her. And after a week or so she started to look very skinny. So we looked up how much food she should get and we were giving her about half of what she should have been getting. So we bumped up her food intake so she could get that weight back up to a healthy level. But right after. She started having diarrhea. It’s not bloody or discolored. And she is not displaying any other symptoms. She’s still had her appetite. No fever. She still runs around and is energetic. She just keeps having diarrhea.

There are many causes of diarrhoea especially in puppies which may be caused by dietary problems, infections, parasites, foreign objects, poisoning among other causes; you could try to give an anthelmintic (wormer) and to supplement the diet with a little plain canned pumpkin which may help firm up the stool. If there is no improvement, you should visit your Veterinarian for an examination as there may be an infection; if you haven’t started vaccinating yet, I would recommend you do so.

Our puppy has had diarrhea pretty much from day one, ranging from soft poos to puddles. we have been back and forth to the vets, she has had prebiotics, been on GI diet and very little helped (she also drinks a lot by the way). she has had blood tests, urine tests and fecal analysis. They found Giardia which was treated and is now clear but no other tests found anything. She is back on Royal canin puppy food (as the GI food seemed to make no difference) and whilst she is generally ok she remains soft. She is ravenously hungry all the time but if we increase her food intake at all (even by introducing an extra meal) everything seems to get worse. She is bright and active (and hungry), we just want to get to the bottom of it as we are at our wits end, she is very skinny and we want to build her weight up but just aren't able to. Any suggestions of where we go from here? In her hunger she is also a poo eater - less so when fed more....

The only thing that I can think of that may be happening that is somewhat common might be a food allergy or intolerance, as your veterinarian has covered a lot of the more common bases and reasons for diarrhea in puppies. The way to determine if she does have a food allergy would be to transition her to a hypoallergenic diet that is available by prescription from your veterinarian, and see if things improve for her. There are specific diets for this that have had all the antigen removed from the food, so that her GI tract doesn't react to them. Barring that, it may be time to see an internal medicine specialist. I hope that you are able to get to the bottom of her problem.

My dog has been having recurrent episodes of diarrhea. We got him in November when he was 6 months old, he has had 4-5 episodes since then lasting about 2-3 days (resolving when we switch him to a rice/turkey diet). They are usually very watery/"explosive" stools. Once it resolves we switch him back to his food (Blue Wilderness) and he stays without diarrhea for about a week or two then gets it again. He was tested for worms after the first episode, and was negative. He has the tendency to drink from puddles on walks, but we try to stop him so I'm not sure it occurs consistently enough to be the cause. I'm wondering if it could be related to his food and if I should switch dog foods.

Thank you for your email. It seems that it might be related to the switch back to his regular food, yes, although I can't examine him so can't say for sure. Your veterinarian can give you some ideas for good GI diets for dogs that have food sensitivities, as well as make sure that he is still negative for parasites such as Giardia and Coccidia - it would be a good idea to have another stool sample checked to make sure, as some of these parasites can have a 'waxing and waning' type of pattern.

Snickers was spayed, I took her home all was good, on the tenth day I took her to the vet for a checkup on the sutures and everything was good. That day I changed her food from royal canin medium sized dogs to royal canin maxi sized dog, and gave her deworming pills, and rubbed antibiotic cream on the sutures. Since that day she's had diarrhea, I've tried changing her food to chicken and rice, that didn't help, I've had her fast 24 hours she had a solid poop but as soon as I put her back on her food she went back to diarrhea. I took her the vet, they gave her an anti immetic shot and another one for a fever, she still has diarrhea, I've changed her food to gastrointestinal good and she still has diarrhea. All this is over a month and a weeks time. Not sure what else to do.

Thank you for your email. Common causes for diarrhea in dogs include parasites, dietary indiscretion, food intolerances, and intestinal infections. Without examining Snickers, I can't comment on what might be going on with her, but it seems unrelated to the surgery with the time frame that you have described. If she hasn't had a fecal checked for parasites, including Giardia, that would be a good idea. There are anti-diarrheal medications and probiotics that can help with uncomplicated conditions. It would be best to follow up with your veterinarian to see what the next step is in resolving her diarrhea, as they can examine her and have whatever tests performed that might be appropriate. I hope that things resolve for her.

My puppy Thor is about 4 and a half months old, he’s a pit bull, we recently switched his food and at first he had solid stool. Now, he’s having awful diarrhea, it almost has a red tint to it and I’m afriad there might be blood in his stool. We switched his food bc the food we originally had him eating didn’t provide enough nutrients for him. I know the food we are feeding him doesn’t have any corn or wheat but I’m getting concerned about his stool. His attitude is the same, but his temp is high. Could this just be switching the food too fast or should I seek vetenarian help ASAP?

I have a puppy and about a month ago I changed her food to one with less processed ingredients. Since then she has had diarrhea. At first i just thought it was the change in food, but it hasn’t gotten much better. It starts mostly solid then at the end it’s liquidy. She has no problem holding it and never goes in the house. Other than the diarrhea itself everything else is completely normal. It’s a chicken based dog food. It’s definitely her food because she is an indoor dog and doesn’t go outside unless I’m walking her. So I see everything she does. She’s an Australian Shepherd puppy almost 4 months old. I don’t know what food to change to, and how will I be able to tell if it’s better until a couple weeks in since dogs usually get diarrhea when you switch their food? Any suggestions?

Thank you for your email. It isn't normal for her to have had diarrhea for a month from a food change, and food allergies are not as common in puppies. Common causes for her diarrhea might be parasites or an intolerance to the food itself vs. the ingredients - different foods are different quality. It would be best to have her examined by your veterinarian, as she may be due for preventive care regardless, and they can check a stool sample for parasites. Once they have looked at her, they will be able to make recommendations for food, and help you to clear up her diarrhea. I hope that everything goes well for her.

My 1.5 year old beagle does not show great interest in her food and doesn't eat the full meal. I'm switching her to a new food to see if she will like it more. I'm switching from Nutro small breed to Wellness Core small breed. She's 14 lbs. She's started to have diarrhea the second day of transition and had 2 episodes so far and one vomit episode. She has been drinking watery, and was playful. Do I continue with the food transition or withhold food for a while?

May be withhold food for a few hours and start again once the gastrointestinal tract has calmed down; some gastrointestinal upset may occur due to a change in diet but if there is no improvement you should switch back to the old diet or feed boiled chicken and rice until everything calms down. If there is no improvement or the diarrhoea continues, visit your Veterinarian. Regards Dr Callum Turner DVM

My 11 month old dachshund is having her first heat and has now developed diarrhoea she has been at least 8 times today/night. We are currently staying with family in France and had to change her diet 12 days ago due to France not having her usual food. So is the diarrhoea likely to be because of her heat or because her food was changed 11 days ago ? She is still lively and playing and eating and drinking still.

Generally we would have expected diarrhoea from dietary change to have occurred within the first two days or so of the diet change, most likely this bout of diarrhoea is due to a different cause which may be attributable to heat, infections, parasites, poisoning, foreign objects among other causes. Keep a close eye on Leah and ensure that she is hydrated, you may need to visit a local Veterinarian if the symptoms continue just to check her over. Regards Dr Callum Turner DVM

Runny sool

I have a 5 month , old Sheppard mix who I just adopted about 2 days ago. I bought both her dry and wet food at the shop within the humane society that I adopted her from. First night her stool seemed normal, but now going into the 3rd night her stool is even more runny than before. They gave me both the wet food and dry kibble for adult dog even though she is still a puppy. Would this have anything to do with why her stool is so runny? I bought what they told me they were feeding her so I wouldnt have this issue, but now am considering to switching to puppy food. Please advise, thank you

The switch between puppy to adult food depends on the food manufacturer and the breed of the dog; however the diarrhoea may be related to diet but also may be caused by stress (new home), parasites (not uncommon in shelters), infections among other causes. You should keep on the food that was being fed and monitor for any improvement in faecal consistency since it may be stress related, if there is no improvement by the weekend visit a Veterinarian for an examination and faecal test.
