Soft Tissue Surgery for a dog with Anal Tumour. I am Bi. I am a 13 years old male dog. I have a terrible mass on my anus which has been bleeding for a long time. My owners thought I am the only child and they are so scared of the neutering surgery for me and this mass is from the male hormon from intact dog. I was going to die because of the bleeding and infection. Everyone wanted to put me to sleep but my family wanted to give me a chance and the vets also wanted to help me. Amazing story. I survived. Thank you very much to the vets at Saigon Pet Clinic
