Puppys are very prone to upset tummys and can easy get a bit if gastroenteritis which puts them off their food and can cause diarrhoea. However puppys also can do silly things like eat socks etc. I would be inclined to go into the vet for a check up to rule out anything more serious and ensure the pup isn't getting dehydrated.

    Hello, sorry to hear about Jiggles. I would recommend having Jiggles evaluated by your veterinarian today. It is possible that he may be infected with parvo which would require medical management. He could also have eaten something that is causing him to feel sick which may not be as serious as parvo. Aside from a parvo test, your veterinarian may also recommend x-rays and bloodwork. In the interim, you should offer Jiggles access to water. Hope this helps and best of luck.

    This could be many things such as parasites or bacteria that the dogs are spreading to each other. The puppies also have a concern for Parvo virus which is very serious and can be fatal. Not eating normally for a month is concerning and not normal. All three pets need to see the veterinarian to figure out what is wrong. The doctor will need to test them for parasites and bacteria. Try to get them in today if possible. I hope this is helpful and please feel free to post any additional questions.

    Thank you for submitting your question regarding Nala. I recommend that she sees a veterinarian today. Unfortunately, vomiting and diarrhea are signs of parvovirus infection. This virus is common in her breed. If this is not the case, then a parasitic infection is the next most likely problem. Parasites are also diagnosed on fecal testing. Being so young, it will be easy for her to become dehydrated from losing fluid in the stool and vomit. Once her problem is identified, then she can be started on treatment. I hope this information helps!
