Tucker eats about half a cup of food per day. I give him one cup, but he never eats it all. Of course the spoiled rotten baby does get his fair share of treats(okay, okay, more than his fair share,LOL). And he poops at least 3-4 times per day. He eats science diet. How much does your dog weigh? You could always talk to your vet about it next time you're there just to get their opinion.
