I would definitely check with your Veternarian BEFORE trying this. When Rusty got neutered he bothered his stiches. I used my finger and dipped it in Bitter Apple. I rubbed it around the perimeter of the stitches NOT on the stitches. When he licked he of course, tasted the bitter apple and that stopped it. I didn't spray because I didn't want to get any on the incision which would be very painful for him, so I just used my finger and rubbed in around the area. It worked. But even after checking with the Vet, be VERY careful not to touch the incisions with the Bitter Apple. Good Luck!
