My 80 pound pound puppy/bird dog got hit by a diamond back about 15 years back. Right on the nose. We lived out pretty far then and it was an hour or so to the closest vet. Went over 100MPH gettin the dog there. The vet says "Hum. Looks pretty bad." Took him in back. Little while later a "nurse" comes out and says, "He's in bad shape. We're gonna give him this, that, and the other. That's gonna be $1300. We have financing available". I said, "WOW. Hold on a minute there. I can't afford $1300". She then tells me that for about $800 they would put the dog down. I told her to just bring him back out and I will deal with it back at the ranch. Then she says, "Well, we do have this other treatment we can do". I say, "How much is that?" "$200" "Sign me up!" Dog was fine the next day.
Moral of the story is, just like a lot of doctors these days, don't think that things that make the doctor/vet more money aren't pushed on us. To some immoral people that's all life is about. Dog lived another ten years and wouldn't get anywhere close to another snake, although he would bark like hell and circle them when he saw one.
