I often joke about how I sometimes wish my dogs could stay looking like puppies, but with their grown-up manners. Of course, that's a silly thing to want since my boys are just as cute and wonderful as adults as they were as puppies.
And they've learned to listen and that the bathroom is outside, not in mahm's bed.
Occasionally, though, an animal is born with a condition that keeps them looking little and cute for their whole lives.
