Q. I have 3 shihtzus 2 have diarrhea seem fine otherwise I did change there diets in the last 3 days for all. They eat imams canned food twice daily now
A. Some dogs have more sensitive stomachs than others so a change in diet may have been enough to cause it. Did you introduce the new food gradually? We normally recommend doing it over 7-10 days (a quarter of new food with 3quarters of the old food for a few days, then half and half for a few days etc). Was there a reason for changing their diet? If they were fine on the original food then stick to that. If the diarrhea doesn't clear up in a few days then get some pro biotic paste from your vet.
