Please listen to the good advice others have given you. Invisible fences systems are not the right thing for yorkies. I had one on my golden retriever and he did wonderful, but he weighed 100lbs. I've shocked myself accidentally many times on his collar and believe me, IT HURTS! If I had that on my yorkie, it would seriously traumatize him, maybe worse. No way he could take it. Also, there is a very real threat of hawks, owls and even other dogs that can injure and kill small dogs that are left unsupervised and unprotected outside. |
