I have had to shoot 6 in my lifetime, I got called when no one else would, or could from the time I was 16. I am thankful I haven't had a bad shot yet, but if at all possible I call the vet and euthanize and have for years.
Yes I still think back and feel sad about every single one of them. But, I think if I had it to do over, I'd still make each well placed shot, just like I did then.
I know it's been bashed to death as being horrific and cruel, but seriously isn't it a better alternative than suffering? Now mind you, I am not talking about (insert name) down the street that shot his poor crippled up horse 9 times because he couldn't shoot the broad side of a barn. I mean a well placed, planned out, one shot, and done deal. I know ill placed shots happen, and they aren't pretty. I just wonder how many would seriously choose a bullet over suffering if euthanasia was hours away and the injury or trauma of a terribly painful nature.
