The mare is around 20 years of age, she's a rescued horse and at this moment she's at a horse shelter for almost 2 years now. Her previous owner had abandoned her after she fell in a canal, they let her there to die.
The doctor told us to euthanize her. She sometimes refuse to walk, and after she laid down she can't get up without some help. The knee joint seems to be painful to touch because she pulls back her leg when I do that.
Besides of those problems she's a very kind and sweet mare.
Sorry for my english mistakes.
