Its a worry when our dogs get old to know when and what to do. When I was asking the same questions, a vet told me that when your dog loses complete interest in the people they love and the food they like and they look and act depressed, then it is time to think about letting them go...dont stress....you will know when the time comes. Dogs can cope very well with deafness and blindness as long as they have the support of their family (pack).
