Help Jay, bitten by a rattle snake.

Our precious dog Jay was bitten multiple times by a large rattlesnake while protecting myself and 2 little girls.
I heard her bark, but this bark was different. I looked out our sliding glass door, and saw her look at me then run to my little girl's play house. As I opened the slider to see what it was she was barking at, I heard the sound of the rattle, loud and clear. I told my little ones to stay in the house and I tried to call her and my other dog in. As I began to round the play house she went on the attack to remove the threat. I believe our brave girl attacked the snake to keep it from getting to me. Thank God my little girls werent outside playing when this rattlesnake decided to hang out by their play house. Jay has several punctures, and is believed to have been bitten at least twice, other punctures may have happened as she was shaking the snake, as she has punctures in her jowls, nose, chest and near her eye. Anti venom is very expensive, and this vet bill is huge. Any donation is appreciated, and should we reach our goal, any remaining amount will go to a local dog rescue. Thank you all so much for your concern, input, and prayers. Bless you all and thank you again so very much!
