I have an older shih tzu that had a large wart on the side of his body. He kept scratching it with his hind leg and it would bleed. Took him to the vet and the vet wanted $175 to remove it. I thought I'd try a home remedy first so I tried the castor oil and turmeric remedy for tumors. I mixed some turmeric with castor oil in a small jar so I'd have it handy. I cut the fur all around the wart and put the castor oil/turmeric paste on the wart. Since turmeric stains, I put some gauze and then 2 layers of some heavier material over the wart. Then I wrapped a wide stretchable bandage around his body a couple of times, being sure not to make it tight at all, just snug enough to hold everything in place. After that was done, I put a sweater on him to make it hard for him to scratch. I treated him 3-4 times a day. It's been a month and the wart looks like it's gone. I'm still treating him for a few more days to be sure the wart is completely gone. The bandage and sweater are stained from the tumeric but he never got any on the furniture or carpet. He also started getting a wart on his bottom eyelid so I put just castor oil on it every night and it looks like it's going away. I've been putting the castor oil on his eyelid for a month now.
