My father thinks the world of their dog. At 16 and poorly the dog will soon need to be put down. The problem is is the dog isn't around my dad goes and looks for him. last year we popped to the park and accidentally forgot to write it on his board. we took the dog, by the time we got back dad was frantic. He had even called the neighbour in. I think he will only intermittently remember that the dog is dead if at all. This could cause major issues as he will go looking for him if mum needs to go out for anything. also it must be a nightmare for the grieving process. has anyone dealt with this before please and do you have any tips?
