One of my three dogs, a six year, has gone blind with SARDS. He copes very well and is a happy little bloke. I was considering going back to work for perhaps a year and don't know if he will cope okay by himself all day. I have two other dogs but they don't realise he is blind and one of them can annoy him wanting to play so he would be better to be kept away from him when I am not here. Normally when I go out I leave them together in their dog pen but that's usually only for a couple of hours, not all day every day. Suggestions?
