old man dexter

dexter asleep last night recently i have had a few concerns about him and his age he is ok but i sometimes wonder how long he has left i think he is a lot older than people say he rests more now but is in good health and plays with the dog more now usually chasing him away cos bronx wants to sniff him and steal his food last night he had pilchards as a treat as its technically his birthday in november but he wanted them early
