4 year old female Airedale mix had warts on her feet that she was licking constantly. I was worried she would get them in her mouth. Dr. Pitcairn recommended a single homeopathic dose of thuja. I used 30c which is what I had. 1 dose of four pills. Then I started giving her a mushroom supplement to build her immune system. I rubbed her paws each night with castor oil which she just seemed to lick off. 1 month later no warts. I am still giving her the mushroom immune support supplement.
