My dog lily is 11 months old. She has had diarrhea for a day now. I have fed her boiled chicken and rice since then. She is up to date on her shots and has been acting and eating normal. But I have noticed today that she has a small amount of foam forming around her bottom mouth and extra amount of saliva. Should I take her to the vet?

Thanks for using Petco Pet Education Center, formerly Petcoach! Excessive salivation is often a sign of nausea. Nausea and diarrhea can occur secondary to conditions such as inflammatory bowel disease, dietary indiscretion, parasites, among other possibilities. I recommend that you have Lily evaluated by your veterinarian for further assessment and treatment. At the very least they can start her on medications to make her feel better and check her hydration status. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!
