Yes, I think people who assume an injection is more humane haven't seen it because like I said, If I could do the alpaca situation again, I'd have had him shot 100 times over.
I do not agree with people who say if you can't afford a vet, don't own the horse. . . like I said, a huge amount of people can't even afford to go themselves when they need an antibiotic for THEMSELVES . . . It makes no sense to say not to own animals if you can't afford high cost surgery or high cost emergency care with the animal overpopulation and neglect and starvation and euthanizing of healthy animals - any kind owner who does what they can is doing that animal a favor. . . what would happen to the MILLIONS and Millions of animals that would be homeless if everyone who could afford colic surgery or cancer treatment on their horse or pet dumped them or hadn't bought them in the first place - where would they go? It is just hoping for an ideal situation that doesn't exist - a utopia, if you will. . .
The fact you worked with a vet over the phone and the wound seems to have healed fairly well is more than a lot of horses could hope for.
I just personally don't have the will power or stomach for such medical care and am so sensitive to pain and such, I am not sure I'd not have put her down if I could get a vet to do the care, and I'm not saying that would have been the best option because it sounds like you were able to manage her pain and she is recovering.
As for barbed wire, that is common here and more than minor injury when it is strung right is very uncommon. I do not use it because I also had a horse have an injury with it while I was a teenager. He was never sound again. Still, my horses have hurt themselves with corral pannels, on rocks, in trees, in stalls, on t posts, etc. . .so you never know, if they can find a way - they will hurt themselves on it. . .be is barbed, wood, high tensile, whatever.
