Online dog adoptions don't address the dog and owner's compatibility, which can lead to serious problems. That was the case with Amigo, a greyhound that was adopted by a well-meaning woman in the Netherlands. She wasn't a strong leader, and Amigo became aggressive on the leash; he even attacked several neighborhood dogs. Amigo's owner realized he couldn't handle Amigo and sent him back to the shelter. Now, Cesar meets three different families to find Amigo the strong leadership he needs.
