This sounds like she has intestinal parasites. Young puppies usually have roundworms and often hookworms and can have a swollen stomach as a result. Left untreated they can cause anemia, diarrhea and poor health in a puppy. You can purchase pyrantel dewormer at PetCo. Follow the label directions. I do also recommend a veterinary exam with fecal check and to start her vaccinations. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Bella.

The symptoms you describe sound like large bowel diarrhea, colitis. Colitis can be caused by intestinal parasites, infection, stress, and dietary indiscretions among other possibilities. I would encourage you to have Bella evaluated by your veterinarian before she become more sick. Be sure to take a sample of her feces with you to your appointment. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

The diarrhea looks very dark, this is usually a sign of bleeding from the upper gastrointestinal tract, it is advised in such a case to seek veterinary medical attention as the condition may be very serious, i recommend taking Emma to the vet ASAP.

My puppy has diarrhea, swollen stomach. Is her diet the cause?

Thank you for submitting your question regarding Tiara. I recommend that she sees a veterinarian for fecal testing. Intestinal infections, especially parasites, are common in young puppies. If this is the case, she will need specific medication. I do not recommend feeding milk as this can cause gastrointestinal upset in dogs. Puppy formula will be easier on her stomach. Finally, offering puppy food will provide her better nutrition. I hope this information helps!

Why is my 7-week-old puppy's belly big? Is it worms or normal?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Puppies should be dewormed every 2 weeks from 2 weeks of age to about 10 weeks of age. She can still have worms. But in general puppies of Bella's age tend to have fat little distended bellies, just like human babies, which is very normal. They tend to look even fuller after eating. It is time to start her vaccinations so the Vet can also feel her belly to be sure everything is fine. I wish Bella the best!

Why is my 3-month-old puppy still bloated after worm medicine?

HI, thanks for using Petco Pet Education Center, formerly Petcoach! Puppies tend to have a more bloated belly. Intestinal parasites are usually the main cause of this. Sometimes the intestines are more gassy in puppies too. I would give the dewormer some more time. If there is no improvement by a week i would have her examined and bring a stool sample with you. Sometimes changing puppy food can help as well. She is due for vaccinations so a Vet exam should be happening soon anyway. Good luck!

My puppy's belly is swollen after deworming. What should I do?

You can get this swollen belly from intestinal worms. If there was something to give Roxie for it, the vet would give it to her. You have to wait and see if the deworming treatment helps. If it does not, have her seen by a vet again.

My puppy has coccidiosis. Why is his belly bloated and hard?

Your pup sure is adorable! His belly is most likely bloated because of the intestinal parasites and should go down over the next week. I would make sure he is also being dewormed for more routine intestinal parasites (like roundworms and hookworms) to make sure he is covered. You may notice some softer stool during this time but vomiting and diarrhea should not occur and you should contact your vet if you notice this. I hope this helps.

Why is my 3-month puppy bloated, lethargic, and whines when touched?

If she hasn't been wormed then it is likely due to intestinal worm infestation, tomorrow at the vet's they will deworm her and probably vaccinate her as well, the deworming should resolve those symptoms.

My puppy has a swollen belly, is sleeping more, and breathing weirdly.

Please understand that we can only give you so much information via the internet without examining Coco ourselves. I can tell you that based on the photos her abdominal distention looks very severe. I don't think this is related to parasites but it could be. I would be worried about ascites (or free fluid in the abdomen). You should get her to a vet as soon as you can for an exam and either an x-ray or ultrasound.
