I don't know all the details, but here is a link and tells the story of one little dog that caused them to decide to do this.
Veterinary Care Foundation
If anyone would like to know what the funds go toward or how they decide who deserves the money, I would suggest you contact the vet's office to have those questions answered.
And if I were one of those people in financial need and couldn't get my pet the expensive surgery it needs to save its life, I wouldn't care if the funds were for the vet or the the supplies or anything else. I would just be glad there was something there to help out.
In my book, it is all about helping others less fortunate and I'm glad to see this vet's office have come up with some type of plan.
