Knox is 4 years old and he (and his brother Duncan. They came from the same home) has never known the comfort and love of a family. Just abuse. Despite being hit and hot water dumped on him by his previous owners, Knox is truly a great dog that just loves to be with you. He is sweet and happy. He loves to play ball and run with his brother. Good with other dogs when introduced properly. He will need a patient family that won't mind working with him to teach him some things. He does walk on a leash but will pull, he will jump on you when he first sees you because he is so excited and he is not housetrained. He is fully vetted and heartworm negative.
