Yes, the puppy pass has definitely expired at 15 months! And as these two videos show, there's no excuse for a dog that old NOT being trained. The first one was posted by clipke on the trhead about biting and jumping, and the second one is from the breeder of one of my dogs, who is working with her current litter. Pups that have not been sold yet are getting some early training, so they will adjust more easily when they go to their new homes:
Edit: how do I get this to be a live video instead of a link?
