Kieran has a tumor that needs to be removed ASAP

My name is Sharon and I am seeking help for my ESA Kieran. He was brutally attacked and may have permanent nerve damage as well as hearing loss. In the following days he was found to have an anal sac tumor that is double the size and HAS to be removed ASAP. Kieran will be 10 on the 30th of December. He and I have been through hell and back, such as a divorce, moving back to my home state and surviving 2 years of homelessness. It is my responsibility to give him my absolute best I took him for his life and I cannot begin to imagine the fear and trauma he has had to endure, on top of this. PLEASE, PLEASE, PLEASE HELP ME SAVE MY PUP
