THORNIT® is Mr W Watchman's 1907 proven formula, old-fashioned ‘canker’ powder which has been used for many years by pet owners, Thornit kills the ear or anal mite and so removes the cause of the infection. Thornit is perfectly safe, and is also recommended for ear mite in cats and rabbits. Mr. W. Watchman's proven formula of 1907. Especially for ear mites.

Used by the show dog fraternity for many years, Thornit is widely used for animals with ear problems such as itching. This is usually caused by an ear mite which also creates blobs of wax that can be seen in the ear. These blobs can also weep and smell terrible.
It comes in powder form and only a very small amount is needed.
Simply sprinkle a small amount onto the inside of the ear surface NOT the ear hole, and massage in, it is usually a good idea to apply to the paws at the same time. Simply put some powder into a plastic bag, put the dogs paw in the bag and work the powder into the paw and pads and a little way up the leg.
Once the wax starts to move, stop the application.
There are no antibiotics in Thornit, so it can be used in perfect safety.
Contains: - zinc oxide, talc, lodoform, boric acid. (Caution, lodoform can stain light coloured carpets)

Thornit is also available in 20gms and 200gms sizes
