Hello, my Jack Russell is 14 years old and in good health, except now totally deaf. In the past year her behaviour has totally changed, I hate to say senile, but I suppose it's that. She goes absolutely mad scratching at her bean bag bed, stares into space (altho that could be the deafness too) and is generally no longer affectionate. She cries constantly and this is what bothers me: she's fed, walked lots and given lots of attention, but I can't comfort her, or get her to stop. It's just so sad. Does anyone have any suggestions please?
