My Westie baby in need snake bit

Brought my sweet baby to have a beach vacation yesterday He ended up getting a snake bite in the face. Vet states he got pretty much the strongest dose of venom the snake could deliver. Harley is not doing well at all! face swollen, white blood cell count elevated, bloody stool, vomiting. Lethargic. He is being given all he can to save him but the bill is steadily climbing. As of 6am this morning no change. 2nd round of anti venom given. I may get to go see him this evening. No sure cause he is still in critical condition. Please pray for my baby. This is my child. No just a dog. He has saved and is saving my life so if anyone can please help me save his thank you.
Donations can be made here or straight to vet hospital. Number is [phone redacted]. Let them know Harley with the snake bite as they have 2 Harley's there. Thank you for all the prayers and well wishes.
If I get to visit today I will update again and with a picture
