My dog had canine papillomavirus in his paw. It was so painful that he would not put his foot down. Took him to the vet (who did not give a diagnosis) who put him on antibiotics which did not help. When I began my own research into what was wrong with my dog, I came across papillomavirus (warts). They look like cauliflower. I kept reading about Thuja. I had some at home and purchased more. This stuff is amazing. Six tiny pills three times a day. It only took a couple of days to see a difference. I gave it to my dog for several weeks, to just make sure that it was all gone. Easy peasy and the warts are gone!
