Max, my blue Merle collie, we rescued from a rescue centre as the breeders left him there as he could not be sold for profit. He is as good as blind having only a small eye on the left and the sight as good as nothing in the other. That doesn't stop him from leading a normal life. He go's for walks in the forests around here, but is not keen of walking in town as there is a bit more going on there. I don't regret the decision of re homing him as he is literally one of a kind.
On a brighter note, let's have some pic's when you finally bring him home what ever you call him.
