We have a 1yo border collie female.
We have been able to teach her tricks and obedience very early on and she has also been around other dogs since she was a pup. She picks up things very easy and loves doing things to please us.
The biggest problem we have is that she is obsessed with the tennis ball, which all border collies usually are, but the problem with this is, that when she's playing with the ball and another dog comes over to say hello, no matter how big or small, our pup will turn round, snarl and snap at this other dog and then refocus her attention on the ball.
We can usually discipline her by sounding disappointed with her or telling her off and that works when she has chewed something or is being naughty, but no matter what we do, even if we take the ball away,nothing will stop her agressiveness.
we are thinking about puppy pre-school but we are very pushed for time.
Can any of you offer ideas which may work.
