Now I expected this when I started giving the poochies canned food, but how long is it going to last for??? Poor Roxy hasn't had a solid poop in 2 days, and instead of pooping once or maybe twice a day it's been more like 3 or 4! Does the canned just have too much moisture for her? Do I just hold out, and hope she firms up? Should I give her something to firm her up?
