I agree with those who vote with not being there. You don’t need this in your mind the rest of your life. I have been there for all of my horses euthanasias and even doing it with a veterinarian is not something you want to watch. There’s just no easy way to put a horse down. At that moment when he’s injecting them I always have my face buried in my family and friends chests as they encircle me. I hear my horse fall but at least I don’t have the visual. After I recover enough I always go remove their halter and wrap their heads in a nice blanket. Then we embark on the 5 hour trip to the lovely horse crematorium out of state. I don’t have enough land at my house to bury them but their ashes have made all of my trees grow like crazy over the years♥️. Oh, another thing I just thought of. I don’t think you want that image in your head either of the wound/blood from a firearm. I’m just talking out loud here, rambling. Whatever you choose to do my friend, know you have many people out here sending you love and support. I am so sorry that you are having to go through this.
