I picked both yes and no.
Unfortunately, Frisk is overweight. No matter how much I beg my mother and father, they insist that table scraps "won't hurt him". We're working with him, though. We've changed to a better dog food and walk him at least five times a week. We see improvement!
Ethan isn't the kind to gain weight easily, so he's not overweight. Actually, when we adopted him, he was still slightly underweight, but he's fixed that. Also, Ethan isn't the kind of dog that can eat and eat like Frisk can. If he eats just a little too much, we get to clean it up off the floor when he can't hold it down.
