Help Captain Spaulding get his Surgery

My name is Carly, my family dog, Captain Spaulding, is in serious need. He is a sweet, beautiful 5 year old Catahoula Leopard mix. We adopted him when he was 2 and he has brought joy into my life, my parents lives and to the lives of everyone he meets. He is not a registered emotional support dog but he is the one who comforts my father with MS and keeps his spirits up. We just found out that he has bladder stones that are causing him severe discomfort and he needs surgery to get them removed ASAP. The surgery costs around $2000. Neither me or my family can afford that but we are not ready to lose this sweet boy. He is a part of our family and we need to help him. Please share this with whoever you know or if you’re able to help please do.
