Meet Oso This Puerto Rico pup is the total package: Oso is a pro sleeper who sleeps through the night, and he’s already is showing that the knows bathroom is outside (with regular potty breaks). He’s really come out of his shell—playing confidently with all his foster cousins, cats and dogs alike. He’s a smart cookie too! Oso crushes the puzzle feeder, loves sniffing all the good smells in the yard, and after a full day of fun, his favorite place to be is curled up in a cozy lap for cuddles.
