Oreo's Surgery

My 10 year old pup, Oreo, has recently developed a hematoma in his ear, and my family and I cannot afford the surgery necessary to get his ear healed. Dogs get hematomas when blood vessels burst and they develop a blood-filled blister under their skin. These blisters can be very painful, and I would very much love to get him this surgery as soon as possible. My family and I are only asking for what would cover the surgery costs like anesthesia, lab tests, and the actual procedure. Any little donation would be very much appreciated and as an added bonus with every donation Oreo will receive an extra belly rub, which would distract him from his irritated balloon-shaped ear.
