Help Dozer our sons best buddy

Hi everyone, My sons best buddy Dozer is in need of surgery. He’s 9 years old my sons best friend awesome dog full of life but unfortunately has a growth on his chest that’s needs to be taken off. It’s been getting bigger and is starting to bleed so the vet says we need surgery to remove it. Since he is a large breed dog this is going to cost around $800. If you could please help us in our time of need for our Dozer to help him get this awful thing taken off. We will greatly appreciate any help. All donations will go straight to his surgery. Thank you for your time.
