To The Rescue! features 7 different Breed groups with 4 different sizes of dogs in each category. There are puppy, small, medium and large variants for each breed group. The dogs featured in the game aren't meant to represent specific breeds of dogs, but rather to showcase the wide variety of appearances dogs. Shelters often aren't positive about the exact breed of a dog, or they might be mixed. But people are often looking for specific kinds of dogs so they will be loosely grouped based on appearance.
