UPDATE
So after I thought we were going to lose him last spring, this boy made a wonderful recovery and got as fat as butter over the summer. Unfortunately he has now really taken a turn for the worst. His incisors are protruding and overgrown. He has dropped a lot of weight. I bought him a high energy bucket, which he has enjoyed, but seems to have got so much molasses around his face that he has rubbed it and made it sore.
Again, my OH thinks we should 'put him down'. He is thin, has a sore mouth and a sore face. I was hoping that, since he made it through last winter, hopefully I could nurse him throuh this winter too, but looking at the date of my thread last year, this was in March, so obvioulsy, being only January now, he would have a lot longer to survive until spring comes. The vet has again suggested that we let him go (I think around this area, they may not fully appreciate that someone could have a 'pet' sheep). A local breeder came to see him and thought he wouldn't make the winter through. They did say that if he lost the teeth, he would probably be able to graze again, but he's only 4 so I don't think he is likely to lose them natuarally anytime soon. Has anyone ever heard of having a sheep's incisors removed? Or am I clutching at straws and potentially prolonging suffering here?
