ok, here's the deal, hope i don't sound gross, lol. nala has been eating purina puppy chow since i've had her. she hasn't had any problems whatsoever, BUT her poop smells terrible!! I know none of it smells like roses but if she goes on her puppy pad in the hallway even once you clean it up in lingers, bad. so is the puppy chow the culprit (spell??) if changing food would help and wouldn't hurt her i'd do it, but since she isn't having any problems and i've heard it can be stressful on a puppy i can handle the smell if need be. the breeder that i got her from feed her the other kind of purina puppy chow, in the white bag, but i didn't realize this so i got the other so without knowing i switched her food without doing half and half and she didn't have a problem but i guess you never know with these guys. any suggestions for my stinky situation??
