How noble and unselfish of you to realize that the best thing is to let her go.she'll be at peace...maybe you could bring a mold and get a hoof print as a memorial before she goes. That's what we did for my cat when she died. I have her little paw print to remember her by
You have made a very brave decision, it is really hard especially when it's your first horse. Probably the most courageous think I have ever seen was a 11yr old girl get her very sick horse up ( Sparkle had a brain tumor ) and lead her away from the stables to be put down, Helen was in floods of tears but didn't want anybody else to do it and Sparkle would't get up for anyone else.
I had to make the same decision after I had had my first mare for 19 years, it is one of the hardest things to do, but to persevere and keep you horse suffering would only make matters worse.
Just remember the good times you had together and remind yourself that you gave Labre a good home while she was with you, and that at the end you made the right choice.
I am so sorry that this is a decision that you had to make. I can not even imagine! Your horse lived a good life from what it sounds...you loved eachother a long time. As the other poster said how noble and unselfish of you!
One thing I have learned in t=life is that friends come and go but whenit come to our animal friends it seems to be so much more difficult.
I will have you in my thoughts on Friday.
As for a buddy for your other horse sometimes goats or even roosters or cats make good buddies. Even an older pony ...You and your other horse will deal with this as a team...and a bond will begin to grown even deeper then what is already there...
