Tobby, a lot of rabbits live well into their teens. How old is Wince? What kind of a cage does he live in? If it is wire and he only has that be on, that could cause the sores on his paws. Please get something to put in his cage that he can sit on. I use wicker mats in my bunnies cage. I've also used card board. Carpet squares are not suggested cuz they may eat it and that's not good. If his cage isn't cleaned and he is sitting in urine, that could also cause the blisters.
As for his fur, did you know that some bunnies go completely furless when they shed? My bunny lost his fur in patches like you described the first summer I had him. I do think it was due to stress being in a new home (with dogs) and that made him lose more. However, his fur does still come out in huge clumps now during the summer months. As long as Wince doesn't have any kind of skin mites, sounds like his heavy shedding his normal. The is a good house rabbit website, called rabbit.org with loads of information on bunnies. You might want to check that out.
I've had 3 bunnies. They have all been great pets. They have been litter boxed trained and very socialable and loving. My first 2 ran all over my house, my current bunny, a lop earred, stays in my family room. His name is Dougie. I found him at a no kill shelter when he was about 2 years old. He had belonged to a girl attending college and she was not allowed to keep him in her dorm room. Her parents didn't want to take care of him and surrendered him when she went back to school. Dougie had been at the shelter in a hutch for about 9 months when I found him on the internet. He seemed to have forgotten how to hop as he "walks" by raising his back end and walking across the floor. He is 5 years old now, and still "walks". He doesn't like to walk on anything but the carpet, so he stays in my family room. He loves to be petted and snuggle with you, on his terms...on the floor. He doesn't like to be picked up much. Dougie is a tough guy, and has learned to handle the dogs quite nicely. If they bug him to much, he growls at them, punches them and if they still don't get it, he'll back kick them! Dougie spends most of his days now, lounging on the air conditioning vent or stretched out behind his favorite chair. He's a good bunny and not destructive like most and I can leave him unattended with free roam of his room without worrying about him.
