One more thought, Is it called Chronic Penis Infection?? I was reading this online and wondered if it might help you?
Have you tried Transfer factor? It is a realitively new product on the market for animals.
It helps boost and correct the immune system.
I am an RN an Stanford hospital, and have taken this myself for allegies. I have my cat on it for Asthma. It keeps her infection free, and off steriods. She is 16, and is still keeping our puppy in line. It maybe an
autoimmune process going on, and the immune system is not healty to fight it. Anitbiotics do not always help, sometimes the bacteria, virus, mutate. As the medical field is finding out with antibiotic resistant diseases. My website is
http://www.my4life.com/tammycregut. You can order the canine formula there. Also check the home website
www.4life.com. Look under the products for animals. See what other people have experienced with their animals.
Good Luck.
