Owners lavish love on their pets, which is why so many go from non-aggressive pups to being out of control when they're older. People just don't realise their dog must respect them as leader of the pack.
Cesar MillanDogs don't rationalize. They don't hold anything against a person. They don't see the outside of a human but the inside of a human.
Cesar MillanSome dogs could play fetch all day long, while others have absolutely no interest in chasing a ball. Some might love "find the treat" type puzzle toys and others may completely ignore them. The important things are that your dog finds the toy interesting without becoming obsessed over it, and that it is size and safety appropriate for your dog. A Chihuahua is probably not going to be a good match to a Kong as big as she is, and you wouldn't want to risk having your Malamute swallow one of those smaller size tennis balls.
