My family grew up with a 55 lb mutt. He knew every trick you can think of. I have an 11 year old boarder collie, Shepard mix who is about 45 lbs. I've really grasped how to be an effective leader after owning my own dog. I love meeting dogs and getting to know their personalities. I understanding the patience and repetition it takes to train a dog so promise to abide by your rules with your dog. You can trust me with your family.
