Parents have a 11 month old stunningly gorgeous GS pup, she is huge, but she pulls so hard I'm worried about how my Mum will manage in the future to take her for walks. Their other dog (pointer) pulls as well.
They've tried chest harnesses on both, (as well as a muzzle harness along with the chest harness) on the GS but not having any success.
They went to puppy training for a while with the GS but it doesn't seem to have done a great deal of good.
Any advice?
