True. A horse is not like a dog, cat or human. They have special needs. However, if someone wants to spend a million bucks to save a horse, I won't fault them for it.
What is really sad is when you are willing to spend any amount and just don't have it. The treatment this horse is getting is only available to owners with mega bucks. The average or even above average owner would not realistically have this option of treatment. You can insure horses, but that gets cost prohibitive; to carry a policy that would cover this type of treatment is also out of the question for most people who own horses.
I am glad this horse is able to get this level of treatment, and I hope for the best for him.
