So far, springer spaniels. The ones I've met are too focused on their tennis balls and frisbees to listen to me or worry about anything else. I've met alot of other breeds that are more focused on toys, like border collies for instance, but they will still listen to my commands.

I'm glad Timber doesn't have a strong "ball drive." She fetches the ball about twice, and then runs, looks at it, and comes back without it lol.
