What is Obsessed With Food?

Your dog has always had a healthy appetite, but lately, she seems more possessive with her food. So much so that she will growl at anyone or anything that comes near her during feeding time. If you have other dogs, she may snap at them or even provoke a fight during feeding time. This behavior wasn’t always the case. Does it seem that your dog is obsessed with her food? Several conditions can cause your dog to have an increase in appetite:

  • Psychological or behavioral issues
  • Poor gastrointestinal absorption of nutrients
  • Cushing’s syndrome
  • Canine diabetes
  • Parasites

Why Obsessed With Food Occurs in Dogs

Psychological or Behavioral Issues

There are lots of factors that can contribute to a psychological or behavioral obsession with food. Adopted dogs may have had a background in which they had to fight for food, and old habits are hard to break. You may have to be patient and give your dog time to understand that she no longer must fight to get enough food. Other dogs, even those raised together, will fight over food. You may have to feed them separately. Another surprising factor is aging – as dogs become older, they naturally become ravenous. 

It should be noted here that free feeding of multiple dogs often leads to this type of behavior. While it is more convenient, many trainers do not recommend it. They feel that dogs will either be too fat or too thin – and, in this case, some dogs develop behavioral problems when there is not an equal amount of food at a scheduled time for dogs. 

Poor Gastrointestinal Absorption of Nutrients

In addition to seeming hungry at all times, your dog may also show signs of chronic diarrhea and weight loss even with the increased appetite. You may also notice pica – your dog eating things that are not food. Your dog may also experience dehydration as a result of poor gastrointestinal absorption. Any breed of dog may experience poor gastrointestinal absorption of nutrients.

Cushing’s Syndrome

In addition to an increased appetite, you may also notice increased drinking and urination in your dog. Cushing’s is normally caused by a tumor in the dog’s pituitary gland. Often, owners mistake Cushing’s as part of the normal aging process, and sometimes vets will miss the disease altogether unless they specifically test for Cushing’s. Your vet will order a series of tests, one of which may be adrenocorticotropic hormone (ACTH) stimulation test. He may also order other blood work to ensure that no other disease is possible. Often, the syndrome may be successfully treated with medication. The Poodle, Dachshund, Boston Terrier, Boxer, and Beagle are most prone to Cushing’s.

Canine Diabetes

Traditionally, diabetes is marked by excessive thirst along with weight loss and increased urination output. Normally, a dog suffering from diabetes will have an increased appetite in response to blood sugar spikes brought on by insufficient insulin production. Most diabetic dogs will put on weight as a result of the increased appetite, although a small number of dogs will lose their appetite for food or water.  You may also notice urinary accidents in the house, vomiting, dehydration, and lethargy. Dogs of any breed may develop diabetes, but Miniature Schnauzers, Standard Schnauzers, Poodles, Australian Terriers, Spitz, Bichon Frise, Samoyeds, and Keeshonds are more likely to acquire diabetes compared with other breeds. In dogs, a genetic predisposition makes a dog more likely to develop diabetes than weight or exposure to certain drugs. 


The Center for Disease Control defines the term parasite as “an organism that lives on or in a host organism and gets its food from or at the expense of its host.” Parasites can be fleas or ticks or they can be internal parasites such as hookworms, roundworms, tapeworms, or non-worm parasites such as coccidia, giardia, and spirochetes. Dogs can acquire parasites in a number of ways. Sometimes puppies inherit the parasites from their mother when nursing; sometimes adult dogs inadvertently lick the parasite’s eggs. Hookworms burrow into the skin and head for the intestines. Roundworms, whipworms and tapeworms are most likely to be the reason your dog would have an increased appetite as they cause malnourishment in dogs. A quick trip to the vet, where he will likely take a stool sample, can prove whether or not intestinal parasites are an issue for your dog. Fortunately, most cases can be treated with dewormer or other medication.

What to do if your Dog is Obsessed With Food

If your dog is obsessed with his food because of a psychological or behavioral problem, it is probably best to separate him from other dogs when he eats. With patience and some conditioning steps, you can help your dog understand that he is not threatened at meal time. If your dog is getting older, you may not be able to easily change his behavior. Your vet may be able to put you in touch with a trainer who can help you and your dog. If you notice your dog eating and drinking excessively, get to the vet where he can do blood work and a urinalysis to diagnose possible diabetes. Regular trips to the vet will help you to prevent parasites in your dog as he will give your dog routine dewormer. Regular trips to the vet can also help to detect Cushing’s syndrome at an early stage. Remember, Cushing’s is often overlooked by owners and vets, so if you suspect Cushing’s, start to keep a behavioral journal to share with your vet.

Prevention of Obsessed With Food

To prevent parasites, be sure to keep your dog wormed regularly. Also, keep him from infected soil and water – this is more likely to happen when your dog is around dogs that are not vaccinated or wormed regularly. Cushing’s syndrome is most often caused by a non-preventable tumor; however, taking your dog to the vet regularly and having routine blood work done increases the chances that your vet can catch any irregularities sooner. The same can be said with diabetes – the earlier the disease is diagnosed, the higher instance of effectiveness of treatment. 

Cost of Obsessed With Food

Treating a food obsession in your dog can be expensive depending upon the cause of the problem. Treatment for intestinal parasites can range from $200 to $500 depending on the cost of living and the severity of the infestation. On average, the cost to treat intestinal parasites is $300. Diabetes can cost an average of $3000 to diagnose and treat.

Thank you for your email. Some dogs really are just more interested in food than others, and if Ruby gets the occasional snack as a reward for her staring behavior, she will be even more motivated to watch the next time. To stop that behavior, it is important that she never get rewarded for it, not even a little, and not even occasionally. If she learns that she never gets anything by staring at you, she should stop staring at you eventually, although this behavior can become more intense before it finally improves. Some dogs do respond better to twice daily feedings, so you might want to split her food into two helpings and give one in the morning and one at night. I'm not sure what her physical condition is, it would be a good idea to have her examined by your veterinarian to make sure that she is a good body weight and appears healthy. She may benefit from a change in dog food that makes her feel more full, as well - your veterinarian can talk to you about that if needed.

obsessed with food

My dog has always been obsessed with food. He always eats everything in his bowl right away. Unfortunately, he developed a bad habit of begging for food and is often fed by other family members from the table. However, lately his obsession has gone to a new level. All he wants is food. If you are sitting on the couch and he is looking at you and you make a sudden movement, he runs to his bowl. Also he has started just barking and whining at me until I get up to feed him. It’s hard to enjoy spending time with him because all he cares about is food. I don’t know if this is related but he has started to paw at us more. We will be on the couch and he’ll paw at us, one time he turned off my computer.

Thank you for your email. Unfortunately, giving in occasionally to his demands will reinforce his behavior, and may amplify it since he knows that he will be rewarded occasionally. Since some of your family members do feed him from the table, he has probably learned that he will get a reward if he is persistent enough. Without seeing him, I'm not sure if he is at a healthy weight, or underweight, but he may benefit from a good quality senior diet at this time in his life, if he is missing calories or nutrients. It would be worth an exam by your veterinarian to determine if he is missing anything is his diet, or is just learning behavior. They should be able to suggest to a good quality senior diet that you might transition him to if he is otherwise healthy, that might make him feel more full.

My dog, Rey, is a year and a half old (his birthday is in May). We got him when he was only 12 weeks old from a shelter, so we are not quite sure what his breed is but he does look like he has pit in him. The shelter told us "Australian Cattle dog mix." Once he turned about 8 months he started having aggression issues toward other dogs, only regarding resources. He would snap and try to attack dogs that shared water with him, ate or even smelled food around him, or played with his toys. He was fine with us, though. About a month after his first birthday, he bit a puppy and held onto her face. He broke her cheekbone. We kept him completely away from other dogs at that point, but he was still okay with us. We were able to put our hands in his food bowl and take things away from him. About two months ago he bit my fiance in the face while they were sharing food (something we have done with him millions of times before). A day or two after that our friend was petting Rey while Rey was chewing on his bone. Rey whipped around and tried to bite our friend, but luckily bit his phone instead. We sent him away to training because obviously what we were doing with him was not working. He was only supposed to be gone three weeks and the trainer has not given him back yet. She said he is the most food obsessed dog she has ever seen. With her, he refuses to go outside to the bathroom, just so he can eat sooner and started going to the bathroom in the house (he has been potty trained since day two when we got him). We took Rey everywhere with us from the minute we got him. He would go to dog friendly stores with us, on walks, to the beach, on vacation, etc. I'm sure it's probably a behavioral problem but it just seems so extreme that I'm wondering if maybe there is something else going on. I read about parasites that can cause aggression or something else. He has always had stomach problems starting around 6 months old. He would go days without eating and we would have to put him on chicken and rice. He would have diarrhea with blood in it. He would throw up all the time. The vet could not figure out what it was. He tried antibiotics, probiotics, changing his food, etc. Is there something that could be causing this aggression, relating perhaps to his stomach?

This is a difficult question, but on the surface it still looks like a behavioural problem; behaviour can sometimes be changed due to parasites, head injury, poisoning and other factors but the behaviour is a general change not just with food which is making me lean more towards the food aggression than anything else. Parasite control (worms, fleas, ticks etc…) should be part of your disease prevention plan along with vaccination an healthy lifestyle. A certified Trainer would be more knowledgeable on the behavioural side than myself, but it may be worth visiting another Veterinarian for a once over to be on the safe side.
