These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.

Thanks for using Petco Pet Education Center, formerly Petcoach! It would be recommended to have him re-evaluated. If they have not tested him for intestinal parasites then that would be the next step. They could also consider another anti-diarrhea medication such as metronidazole. Another consideration would be to start him on a sensitive stomach diet. Good luck and best wishes!

Thanks for using Petco Pet Education Center, formerly Petcoach! Gastroenteritis means an inflammation of the stomach and intestinal tract. Typically, the symptoms of this are vomiting and diarrhea in dogs. Gastroenteritis tends to be a transient condition that resolves with treatment, such as a bland diet, anti-nausea medications, fluids and anti-diarrheals. If it does not respond to treatment or becomes a recurrent issue, it can be indicative of a different disease process, such as inflammatory bowel disease. If his signs do not improve or worsen, I would reach out to his regular veterinarian to discuss what further testing and options may be needed. Good luck!

Hello. In some cases, dogs with severe gastrointestinal disease will need to be hospitalized, administered IV fluids & continue on systemic medications that can be administered by injection. This may be the quickest way to get your pet well, especially since it has been a week & he is still not well. If bloodwork has not been done, this would help in perhaps understanding what is going on. Call your vet to report his lack of response to the current treatment & go from there. I hope all is well soon, & thanks for using Petco Pet Education Center, formerly Petcoach.
