Reader Question
Our dog was put on ZD prescription dry food after a bout with parasits & allergy problems. She got over the diarrhea and parisites after the medication, but her poop is now rock hard & tiny. She goes twice a day but it is a very small amount. Her scratching is not as bad but not totally gone. How concerned should I be about the tiny, ball like poop? She seems to eat, drink and act normal.


Answer from Our Team

Smaller, firmer stools can happen when a dog changes to a highly digestible prescription diet. These foods are designed to be absorbed efficiently and often produce less stool, and dry food also adds less moisture than canned food. If she's pooping regularly, without straining or pain, and is eating, drinking and acting normally, that's reassuring.

The things to watch for are straining, crying when she goes, going a couple of days without a bowel movement, or stools that are so hard she struggles to pass them. Make sure she always has fresh water, and ask your vet whether the canned version of her diet, or a little added fiber that won't interfere with her allergy diet, would help. Don't add new foods or treats without checking first, because that can undo the food trial.

Our guide to dog constipation symptoms lists the signs that mean she should be checked.
