Zeppelins medical cost help

Please please please pray for my Zeppelin he was bitten by a rattersnake. He is a the vet right now but he was bit in the lip. I’m so upset and scared right now. I love this precious dog my heart is broken right now, especially since his treatment is 2700$ I can’t afford so they are doing a lower treatment which freaks me out he’s not going to make it. Please just keep my baby in your thoughts. I’m a single mum so I have enough to cover costs except for 600$
