I have a totally blind chia. We considered putting her to sleep when she lost her second eye.(glaucoma) We didn't want her to suffer. Boy, it didn't take her long to whip us into shape! Carme can let you know exactly what she wants. she finds the doggie door on her own also food and water. She can't jump on the couch or bed but she can get herself to it and then bark (quietly) until you help her up. She will gently paw you when she wants down. Carme has a little snuff-grunt sound she makes whenever there are unexpected obstacles and she will maneuver over or around it. Her outside area is fenced and she never touches the fence. One time before her vision loss,she was out side( we lived on a ranch ) I was in the house. I could hear her barking like she was just going to tear something up,so I thought I would investigate.......Well to my suprise when I got outside Carme ( 4 lbs) had a 2000 lb bull backed into a corner and they were nose to nose. I almost had a heart attack! I tell you this because she has retained her moxy,if something gets to close to her yard ( ie: other dogs, cats ) she still bristles up and gets after them. She can't see a thing. HA HA HA ! I am so glad and blessed to have made the right decision. Micah
