Please donate to help my poor sweet Kai.

My name is Maria and I am fundraising for my poor sweet Kai. He got bitten in the eye by a nasty rattlesnake last night, in our back yard. He is being taken care at the Southern Arizona Veterinary Specialty and Emergency Center in Tucson, AZ. He is in a lot of pain and is suffering. He will need to also have his eye removed if he survives the bite. He is the sweetest and funny little puppy. The initial cost to start the urgent care was $5000, but it will increase for sure. I will appreciate any help, he deserves a chance.
