Will my dog's poop get bigger if I switch to high-fiber wet food?
Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. This is a very good question! The easiest answer is no, Chloe will not have an increase in stool size with the wet food. The reason for this is the increased amount of water offsets the increased fiber content, which is also only really slightly higher in the wet vs. the dry food. The other part to this answer is that some fiber is digestable, so again will not add more bulk to the stool. So if Chloe prefers the wet over the dry, which is fine, her stools should not change much as all, as long as the overall total calorie counts remain the same.
