I use chlorehexidine for wound care in my animals. Call the vet and ask if they like it, but I have had good results with it
Use in animals
For use in animals, it is used as a topical disinfectant of wounds. It is more effective in killing bacteria (bactericidal) than both povidone-iodine and saline, and has residual effects up to 6 hours. Some common brand names are ChlorhexiDerm, ResiChlor, Germi-STAT Antimicrobial Skin Cleanser, Nolvasan Skin and Wound Cleaner, and Nolvasan Ointment. It is also more beneficial to wound healing than using saline solutions alone.[12]
