so glad you asked.. Yes.. it is called NU-STOCK you can google it the bottle says Peirce's Nu Stock for use on all animals..and I am so happy to report that is DOES work!! Dukes hair actually grew back!!! there are a lot of testimonials for you to read. NOW to prepare you it smells like Pine Sol and Duke is not a big fan.. so we clean the area, apply a thin layer then give him a treat in his kong to keep him occupied til he forgets about it. you apply once every 3 days until the result you want. its also good to use if they have an itchy spot! Good Luck to you!
