Furcamper going blind. Your $0.02 to help next trip?

Our 15 year old Toller has cataracts and is nearly deaf. She still holds her head to the side as a result of two attacks of Canine Vestibular Disorder, but she loves to camp! Her smeller is still A-OK and evidently campgrounds have wonderful odors. She is as comfortable in the TT as she is in the S&B (maybe more so)and we keep her on a short lease outside. I worry that every trip will be her last one but we keep on going. lizzie
