With that diagnosis, things suddenly became clear; Connor hadn't been ignoring the volunteers' efforts all this time, he just couldn't hear them. So the shelter then took the time to train him in a way that he could understand - and that made all the difference.
"After that point, one of the technicians here decided that she would teach him sign language, because she had studied sign language in her past. So she started working with him one-on-one, teaching him signs for basic commands," says Adams.
"It was like a flip had switched. All of a sudden he was so well-behaved, and he would learn commands so quickly. It was like he was a different dog. He blossomed."
"He began bonding with us, and most importantly, he learned to trust. He was never a dangerous dog, but he didn't understand that there were boundaries. But once he could be taught doggy manners, he became such a nice dog."
