My poor baby - she was in so much pain after her diagnosis of bladder cancer. She is better now but I can't believe that I will never see her beautuful white face over her stable door again
I am so sorry , you did the right thing for her.
We have had a couple of horses with cancer and they didn't seem to be in any pain until right near the end, it is rare so you have been unlucky.
She sounds a real character and will be much missed.
