My rescue JRT cross is about 12-13 years old. He was previously fully housetrained but in recent months he’s started peeing in certain spots in the house even when I let him out regularly. He never does it when I’m with him but I can leave him downstairs for half an hour and come back down and he’s had an accident. The vet has done tests and can’t find anything wrong and I'm wondering if he has doggie dementia.
He’s also become very aggressive and will snarl and try and bite anyone who sits too close to him on the sofa and makes even the slightest movement. Luckily he hasn’t hurt anyone yet. He’s also not responding to simple commands, although he still enjoys his walks and is running and sniffing like he always did. His appetite is fine. I live on my own and am finding this very hard to manage. I love him unconditionally and would only consider putting him to sleep if he hurt someone. Does anyone have experience of managing incontinence in an elderly dog? And what do you think about the aggression?
