Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If you have not had any blood work done on Rooney, I would get him back to the veterinarian and have this done to help determine what this could be. I am concerned that this could be a cancerous disease process causing this. The fluid in the leg and swelling is from edema from the sounds of it. I am unsure about the testicles but the scrotum may also be filling with edema if there is an imbalance of protein in the body. A snake bite is a possibility but many times you will see puncture marks where the fangs penetrated the skin. There may be a tumor in the scrotum as well, which may be causing the drainage in the leg if it is affecting the lymph drainage to the leg causing the fluid to accumulate more and more. If you have the option to go to a veterinary specialist I would certainly recommend doing so to help figure out what is going on.
