As someone who has a 30 year old retired pony on the feed bill that will stay with us as long as she’s comfortable, and who euthanized an 8 yo dangerous mare without a confirmed diagnosis earlier this year (if you want to hear about that saga, go read the Foal Watch 2023 thread) – I do not think it is common to do convenience euthanasia. I am sure there are outliers, but all the euths I know of have been agonizing decisions to make, none made lightly.
My pony isn’t “sound” – the farrier was here today and she struggles with her hind trims a little, even with bute. Her knee arthritis makes her unrideable because she trips (and actually fell a couple of times before she was taken off duty completely). But she’s happy, in good weight, and has been the most wonderful nanny pony anyone could want.
I am sure I could place her as a companion, and I do loan her out to a summer camp where the kids absolutely adore her. They paint her and brush her and bathe her and otherwise pamper her for a few months, and she loves it. But I will never give up control so that I can make the ultimate decision when it is her time. She has served my family for 14 years now, and deserves that dignity.
The other one? I ultimately could not bear to give up control over her, either. There are so many bad things that can happen to a dangerous horse – at least on my watch, I knew none of them would ever happen to her.
To be honest, I have felt nothing but a profound sense of relief over that decision. I think I did all my grieving for her long before that last day. Having responsibility for the management and care of a vicious animal is a profound stress I would not wish on anyone.
I think In general this community is very supportive of the hard decisions our members sometimes have to make, and I hope that never changes.
