Support Cesar my dogs surgery

I am asking for your support to help me pay for my dog's secondary surgery. Cesar is my 5 year old male pitbull. He is the second addition to my dog family joining my 10 year old pitbull Penny. Cesar still has a long life ahead of him, and he went into surgery to get kidney stone's removed. The vet found one lodged in his urethra and is unable to get it out, and he has referred us to a specialist. In the meantime Cesar was transferred to an emergency vet for boarding over night. We are close to $4,000 dollars into this already without the specialist bill. I am asking for anything you can help with even if it's fifty cents! I know people work hard for their money and just might think its a dog but to me he is family. Thank you so much
