Help Phoenix Find Peace: Emergency Vet Costs

Hi everyone, the time has come that I have to put down my beloved Pitbull Phoenix today his leg stopped working and he has no longer eating and drinking and I just want to ease his pain and of course no vets are open this weekend so I have to take him to the emergency vet which is costing way more than I thought it was if anybody can help with anything it would be greatly appreciated. I just wanna be able to ease his pain and help him along this journey. Thank you in advance
