Dear Dr. John,
We have a Retriever and a Terrier and I awoke this morning to find diarrhea next to my kitchen. The same thing happened last month and, as a simple treatment without diagnostics, my vet gave me metronidazole that seemed to work.
Why does this keep happening? Could it be the brand of dog food, a virus, or something else? We are very careful not to give the dogs any people food or anything that might upset their stomachs. Also, with Thanksgiving around the corner, can we safely give turkey to the dogs without it making them sleepy or causing diarrhea again? W.W.
Dear W.W.,
There are many possible causes to the diarrhea that your dogs have been having. The medication given last time is very effective but is often used in conjunction with dietary changes such as a bland diet
