My dog's stomach is bloated, he won't eat, and he's losing weight. What do I do?

Poor Coco! That much distension in the stomach can indicate fluid (ascites) in the abdomen or an enlarged abdominal organ like the liver. These problems can develop secondary to heart disease, liver failure, low protein levels, severe GI parasites, and cancer. I'd recommend taking Coco to see a veterinarian right away as he needs blood work and X-rays to know why this is happening. This is a true medical emergency as many of the causes of a distended stomach can be life threatening. Thanks for using Petco Pet Education Center, formerly Petcoach and I am hoping Coco has an easy recovery!

Tommy is extremely ill and he needs to see a vet now. He could have gotten into something toxic or could have parvovirus if he isn't fully vaccinated. There is nothing you can do at home for him, this is a medical emergency and leaving him in this state could be fatal. Please take him into a vet immediately.

Sheena should be evaluated by a veterinarian right away! If her belly is swollen she could be suffering from bloat (stomach full of air), a GDV (where the stomach bloats and turns on itself) or she could have fluid in her belly or uterus (pyometra). All of these conditions are very serious and require immediate veterinary care. I hope Sheena is doing ok! Please let us know if you have more questions.

This sounds potentially serious (infection, trauma, foreign object or obstruction). Without a physical exam though, we can't determine what may be wrong with Timmy. Ideally, he should be seen by your veterinarian or at the nearest veterinary ER today. Abdominal x-rays and maybe lab work can be done after an exam to diagnose the underlying cause. Supportive care (IV or subcutaneous fluids, pain medication, etc.) can also be administered as indicated until a diagnosis is reached.

Poor Marshall! It definitely sounds like something isn't right. There are many things that can cause a swollen stomach with weight loss and decreased appetite. Some possibilities would include heart disease, liver problems, cancer, or even internal bleeding. Treatment will depend on what the underlying problem is, so I would recommend taking Marshall to the vet as soon as you are able to. He/she can do blood work and x-rays if needed to help diagnose what is causing these symptoms, and will recommend treatment options depending on what is found.

Please call your vet and give him/her an update and schedule a recheck. Your vet might need to run some blood-work and repeat x-rays to try to diagnose his problem. If it has been a week with no improvement than the medication is not working and your vet needs to determine the cause. He may need some fluids to treat dehydration since he has not been eating and is so weak. Please call your vet right away and discuss.

Not eating for so long is very concerning. Brownish vomitus likely contains blood, and a swollen tummy can be a sign of liver failure, a tumor, a serious infection, pancreatitis, or an intestinal blockage or bloat. By now this is an emergency and I strongly recommend you take Brooklynn to a vet or Pet ER right away. The vet will need to do x-rays and some blood tests, possibly and ultrasound to find out what the problem is.
