Some 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.
Cesar MillanI was blessed to grow up on a farm, and when you're a farm boy, exercise is part of your lifestyle. Like it or not, that environment makes you work out. On the farm, nature is your gym. You walk and run and swim and have to do a lot of work with animals too.
Cesar MillanI do think there are some dogs - although it's very, very rare - that do have to be kept away from all other dogs and all humans except for the one strong pack leader whom they trust. But I think I've run into less than a handful of dogs that were like that in my entire career.
Cesar MillanI wish my kid would act like my dog sometimes. My dog listens to me and does what I tell him to do.
