That's such a tough decision to make.
How does he seem otherwise? Is he still playing and taking joy in life? Do the good moments outweigh the bad? How frequent are the bleeding episodes?
Quality of life is so much more important at this stage of the game than quantity of life. If he's still enjoying himself then you likely have some time left. Go day by day and reassess each day, weighing good moments against bad. If you get to a point where you're hanging onto him for your
sake, not his, it's time to say goodbye.
With Priscilla, she never seemed to lose her enjoyment of life. The pain meds kept her comfy and she was actively playing, eager for walks, eating, peeing, pooping right up till the end. On her last day the nose bleeds were almost constant and she began to show signs of lethargy--probably from anemia... We called and made an appt for the vet to come to the house that night on her way home from the clinic, but the big bleedout came before that and the vet made an emergency visit to help ease Priscilla over the Bridge. It was quite traumatic for us but seemed quite peaceful for Priscilla and she left as she had lived--on her own terms. If I'd had my druthers, though, I wish we'd had that appt a little earlier...
Such sad and difficult times for you.
Give him a big hug for me, k? And keep one for yourself
