My dog's stool is firm on grain-free food. How to make it softer?

Updated on September 23rd, 2025

Pet's info: Dog | Shih Tzu | Male | neutered | 2 years and 2 months old | 17 lbs

When I first adopted my dog I fed him food with grain and his stool was very soft, like soft ice cream, and frequent. I switched him to grain free dog food months ago and ever since his stool is firm, and he only has a bowel movement once a day. Some days, like today, he barely goes but a small amount and it seems even firmer. Switching off of grain free food isn’t an option, so I have been giving him pumpkin which has not helped. What else can I do to give him softer, more frequent stool?

As long as Gary isn't straining to defecate or having other problems I wouldn't worry about his stool seeming to be small or firm. The typical frequency for defecation is once a day to several times a day, and some dogs may not even go once a day. If Gary is straining to defecate or has a history of anal gland problems or constipation this may not be ideal, but otherwise you probably don't need to make any changes to his diet.
