When he was at the shelter in OH he was pretty unresponsive and seemed unable to hear or to see. When I got him he would just walk in circles and seemed oblivious to everyone and everything around him. He was in his own little world. Gradually, he has become much more responsive. He rarely circles now and he will look at you when you talk to him. He follows me around begging for me to drop a bite of whatever I'm eating. His faculties may be a little impaired, but they seem to be improving. The vet is astonished at his improvement. He will come to me to be picked up and sleeps curled up between my husband and I every night. He gets along well with his siblings and he has a sweet tooth, and I do mean tooth because we had to have the rest of them removed...do a search for blind/deaf chi needs a home in this forum. There are "before" pictures there. He has came along way in a short time.
