I posted in this board many years ago about my aggressive Lhasa Apso. It was getting to the point where I dreaded the groomer coming incase he bit her. Well a few years down the line and he's still with us. He's 15 now and has a back catalogue of health issues. Luxating patellas, epilepsy, etc, etc. He's really declining now and think his hearing is almost totally gone. His eyesight is pretty poor too and the aggression has just got worse. We've had to change from a harness to an over the head slip on lead as he will snap when trying to remove his harness. I can't brush him or really attend to basic care, cleaning eyes, bathing etc for fear of him snapping. This weekend he has developed the most foul odour which I strongly suspect is an ear infection. He's shaking his head and agitated when awake but is spending most of the day asleep - this is not at all like him. I'm going to the vets shortly with him but with a heavy heart as I think it may be time to make that call that none of us want to make. I don't know what I'm looking for on here but I just feel incredibly guilty for even thinking this. Any thoughts, advice or words of wisdom?
