What are Gas?

Excessive flatulence in dogs can be a sign that something is wrong with the animal’s digestive system or diet. Dogs generate and pass gas just as humans do, but when observed along with other symptoms may be a cause for concern. Excessive flatulence is more common in overweight and sedentary dogs, but may affect any breed of any age. Don’t hesitate to make an appointment with a veterinarian if your dog is experiencing this condition.

Flatulence is the production of gas through the process of digestion. It is a normal part of the digestive process, but can sometimes be of concern if occurring suddenly or excessively in otherwise healthy dogs.

Diagnosis of Gas in Dogs

Diet

While some amount of flatulence is normal, excessive or sudden onset may indicate a problem. Symbiotic bacteria in the intestines help digest fiber and other components the dog is not able to fully digest itself. In the process of digestion, these bacteria produce gasses. If the dog is unable to digest enough of these foods before they reach the intestine, excessive gas may be produced. The veterinarian will want a detailed account of the kind of food your pet is eating, the frequency and type of any treats, and whether it has been allowed to roam unsupervised (during which time it may have eaten something without your knowledge). Be sure to mention if your dog eats extremely quickly or “wolfs” its food. If no other symptoms are present, such as vomiting or diarrhea, the veterinarian will suspect a dietary cause.

Gastrointestinal Dysfunction

Another cause of flatulence in dogs is the incomplete absorption of nutrients, again leading to excessive fermentation by bacteria, producing gas. There are many causes of poor absorption of nutrients. Inflammatory Bowel Disease can flatten special protrusions called villi in the small intestine. These structures aid in absorption, and damage to them can produce diarrhea, weight loss and flatulence. Parasitic infection can also irritate the gut, slowing nutrient absorption with similar symptoms. The veterinarian will take flatulence into account along with the other symptoms, and order lab tests to find the problem.

Common lab tests for these symptoms may include examination of a stool sample, culturing the bacteria of the gut, some blood and urine tests, and imaging such as x-rays or ultrasound. These tests will help separate out what is causing your pet’s discomfort.

Occasionally, acute (temporary) gastroenteritis may occur after eating spoiled food or taking ill from a virus. This is usually temporary and resolves itself after a few days. Tell your veterinarian if your dog has recently been ill.

Treatment of Gas in Dogs

Diet

Diet modification should start with the reduction of peas, soybeans (if any), fiber, and fat. Too little fiber can cause problems as well, so make these changes incrementally and observe your pet carefully. Don’t feed your pet spicy or acidic foods, reduce the number of commercial treats given, and don’t feed immediately after a run. Dogs are lactose intolerant, so avoid giving cheese or milk-based products.

Gastrointestinal

Treatment for gastrointestinal dysfunction will vary according to the type and specific presentation of the illness as determined by the veterinarian. Acute gastroenteritis usually resolves itself, while parasite infections will require medication and decontamination of the animal’s living space. Inflammatory bowel disease has some treatments available, but is not well understood, and is often resistant to the available treatments.

Recovery of Gas in Dogs

Managing your pet’s diet and eating habits can help curb flatulence and digestive upset. Careful observation and modification of when and how you feed your pet is often successful at reducing flatulence. Keep an eye out for any secretive snacks your pet may be taking during walks or play in common areas.

In the case of parasites, make sure to diligently give the medication as directed and keep your pet away from sources of re-contamination. Give your dog a clean and dry living space, and avoid contact with poorly cared for or wild animals, their feces, and their living spaces.

IBD can be managed in many cases with anti-emetic and anti-inflammatory medication. Follow your veterinarian’s advice and monitor your dog closely. Flatulence is the least distressing symptom of IBD, so even if it cannot be successfully controlled, it does not pose a serious threat to your dog’s health.

Thank you for your question. If she is uncomfortable because of a GI upset, that may pass. It would be best to keep a close eye on her,e and if she develops diarrhea, or vomiting, or continues to be uncomfortable, then having her seen by a veterinarian would be a good idea. They would be able to examine her and see what might be causing the problem. I hope that she is okay.

Hello, I'm so sorry to see that your pup is not feeling well. He may have eaten something that disagreed with his stomach, and now he experiencing painful flatulence. Or he could be having stomach cramps and may have some diarrhea soon. I recommend continuing to monitor him, and if he still seems uncomfortable in the morning to take him to see a veterinarian. Hope he feels better soon.

The gas will resolve along with the other symptoms, but today is just the first day of treatment and it may take a few days to over a week to see improvement depending on severity and treatment prescribed. We generally don’t treat gas as it is more important to treat the underlying condition rather than the symptoms. Regards Dr Callum Turner DVM

No Other Symtoms

My Bassett Hound is Epileptic. he is not on medication because her seizures are few and short and only during storms, she hasn't had one in a long time, and I don't want her to depend on medicines. When I rescued her, four years ago, she had been without food for weeks, had been abandoned in a severe storm. We had her spayed as soon as she was well fed and strong enough, she was very skinny and weak when we found her. The vet found that she had Pyometra, He said that that had been taken care of. She has been happy and well cared for ever since. She was fine until a few weeks ago when she started passing noisy, very foul smelling gas. She's not bloated at all. What can I do for her? We love her very much and are worried that it has do do with the Pyometra.

If Sophie is spayed, she would not likely have pyometra, as the majority of her uterus is gone. Gas can be due to a change in diet, something that she ate, or parasites. If the gassiness continues, it would be a good idea to have her examined by your veterinarian to try and determine the cause, but if she is not showing any other signs, she may be okay.

I'm not sure what testing was done or medications Hachi is on, but is seems that he may need further diagnostics to figure out what is going on with him. He may need lab work or x-rays to find out what is wrong with him. That is definitely not normal behavior, and it would be best to have him seen as soon as possible to try and figure out what is happening with him. I hope that he is okay.

My dog wolfs / gobbles down his food. I bought an item to go in the center of his metal dish and then bought a dish that’s about 1.5 inches that looks like a maze. He of course eats slower with that. I recently changed my pups food to something I thought was healthier (not sure if this is an additive), I also by pedigree and sometimes mixes that with his dry kiblets as a treat.

Gas

My Pit Bull Axle is about 11 1/2 years old. About 6 months ago he started getting gas, and it seem to be more often now. You can see his back bone more and his stomach is bigger and hard. He has always eaten fast, and drinks excessive amounts of water at one time. I have to tell him to stop and relax, and then sometimes he throws up the water. His bowel movements still look the same to me. The gas is very stinky most of the time. This happens all day long, through the night. He could of gotten into anything. I was on vacation and when I came home after 2 weeks he looked like he had lost weight and was gassy. He has been on Purina One Weight loss formula for years. He does get other food, because I have a 94 1/2 year old mom that sometimes throws him her food if she doesn't want it. He has always been at my house, he never goes for walks. But he does eat a lot of leaves when they are dry. He will leave them alone if I say leave it, but I am not always with him.

Blood In Stool

For the past 5 years my dogs have been having major problems. It all starts with extremely loud gas sounds in their stomach,they stop eating and drinking, have fowl odor diarrhea and vomiting. I immediately take them to the vet where they are treated for dehydration and intestinal infection. They sometimes have to stay for days. The vet said it's not a toxin or a poison, nor a disease or disorder. It has to be something that they are getting into causing intestinal inflammation and sometimes infection. I know for a fact it's nothing they are getting from inside the house, so it has to be outside. Thing about that is that, they are let out on a lead cable and can only access a certain area of the yard. I've monitored them and can still find nothing that they are licking or eating that would cause this. I've recently lost one of my babies to this problem and my other baby was sick at the same time as the other, and I almost lost him as well. It's been almost a month and now my baby is getting sick again. It's not just my babies, it's also been other dogs from at least a mile or two away. Could it be something in the air like pollen or something? It seems to happen at the same times every year. Around spring and fall. Please help if you're having the same trouble or know of the problem.

My Chihuahua X Pug has a hard tummy and isn't himself, he has been struggling to sit down and has vomited a small bit of frothy saliva. I can tell he's uncomfortable and not sure if he has eaten something in the garden? This has happened 3 times before and i have taken him to the vets every time straight away. Last time the vet said it was a back problem and that is why his tummy was hard ( from tensing up ) Again this has now happened today and googling symptoms is freaking me out. They are doing a x-ray today and i have left him at the vet to be monitored as I'm worried. I had his anal glands done last week and its still a bit stinky!? I feel like I'm being told something different or they don't know each time??? Any advice or thoughts would be greatly appreciated, Thank you!

Gas Gurgling Acting Abnormal Scared

My dog is an 11year old Shih tzu/bichon. He is very active and healthy for his age. He is also very smart and still has all his wits about Him. However every night he seems to have an excess of gas with lots of gurgling and fear because of it. He experiences it during the day occasionally but only for an hour or two and then snapsmout of it. But it lasts though out the night and keeps us up. He scratches at all the doors and becomes very paranoid and doesn’t seem himself. He doesn’t respond normally and when we let him out in the middle of the night, he just lays in the wet grass until he’s shivering. Our family calls It having the “crazies in his head” because we don’t know what it is.We took him to our regular vet and everything came back normal. We also tried changing his diet but no such luck. We don’t know what else to do. Any ideas? please!
