I really am conflicted. Denzel is a DEAF BLIND rather traumatised rescue.
In terms of engagement with him, I click right by his ear and after that I can stroke him around the head. You can't touch his body. You can't lift him. It's difficult to age him, he has a strange old gait with a hunched back, his front legs move much faster than his back legs. How he is deaf/blind is a mystery but I suspect it was sudden and he may have been beaten or in an accident. He seems to have neurological damage, but that could be that he hunches up because he is deaf blind. I would certainly put him between 7 and 12. he has awful teeth but so do many rescues.
What can he do? He uses the wall of the house to orientate himself. He then moves away from that at the corner and wanders around changing direction as soon as he bangs into something else until at last he has found something familiar like the wall.
He hates the other dogs, he can't see or hear them and then is startled when they crash into him.

He spends most of the time in the utility room, his choice he is not locked in. 6 or 7 times a day he wanders around the kitchen if the kitchen door is closed or if it is open he takes himself for a 10 minute pootle around the house, He isn't house trained but I have tiled floors
He loves his liver pate dog food and chicken. he likes a little pat on the head. He loves sleeping on a sheepskin and being warm. He sleeps most of the day.
He has been with me a year and a bit.... and I've made little progress. Worse still he was apparently more bonded with the rescuer in Bulgaria and actually used to wag his tail at them. he has never wagged his tail at me.
He sometimes howls and I have no idea why and he doesn't stop if I stroke him.
Is a love of liver pate dog food enough. Is not biting me anymore enough? I am faced with taking him to the vet because his back legs seems to be stiff and it looks like a back injury. I haven't yet worked out how to get him to the vet.
I don't want to give up on him. I don't want to make a decision because he is inconvenient and gives nothing back.
I am genuinely torn as to whether he has enough quality of life and I simply don't know whether he is content or miserable. A bit of me suspects the latter.
