Can my inactive dog eat high protein wet food? Will it change poop?

Yes Chloe can have that wet food. As most wet food is primarily meat it has a higher protein content than dry. I usually recommend a small amount of canned with the dry food rather than feeding all canned. As long as the canned doesn't have a lot of fiber in it the poop should not be larger, actually the poop may be smaller due to the decreased amount of fiber in the canned food. If Chloe is normal weight adding some canned to the diet is fine but if she tends to gain weight or she is already overweight then I do not recommend adding wet food to the diet as you are adding additional calories which may get her heavier.
