(Dr. Smith's) Received excellent reviews in Michael Plumb’s Horse Journal. Soft Kraton rubber teeth have a massaging action that flexes the hair and opens the coat so vacuum suction can remove dust, dirt, etc. in 10 minutes! Ergonomically designed. Fits most vacuum cleaner wands with 1 1/4" hose ends. For those with other hose ends, adapters are available at vacuum retailers or repair stores.
