Physique is a measure of how much a pet weighs in Nintendogs + Cats. There are five weight conditions:
On the other hand (or paw in this case), if a pet is Skinny or Underfed, they will require wet food. The player will also need to go to Cafe Petrov as much as possible. One must always remember that the food must be eaten in moderation.
