Hi Kimberly,
My Bichon is blind. It was harder on me then him, when I first found out it was happening. (I cried, didn't know it wasn't the end of the world for him) It was gradual, he started by gradually loosing his sight at nighttime (still did alright in daylight). You will start to notice them bumping into things somewhat. The best thing you can do for them is NOT make any changes to furniture or large objects in your living space. He does just fine now, he has compensated with his acute ability to smell
. Anything I have had to change or move, I have worked with him for a couple days so he knows where it is. He goes up and down the stairs fine still, he appears to be able to count them!!! I am always there when he does go up or down stairs just in case he needs help, so far he hasn't.
