Yes, Neosporin can be used on dogs, but only for minor cuts, scrapes, or small wounds. It is considered safe when used sparingly and correctly as an antibiotic ointment to help prevent infection and promote healing. However, it is important to be cautious: dogs should not lick the Neosporin as ingestion can cause stomach upset, vomiting, or diarrhea. Also, allergic reactions such as redness, swelling, or itching may occur, so monitoring the affected area is important. For deep, large, or heavily bleeding wounds, or wounds that require stitches, veterinary care is necessary instead of using Neosporin. Consulting a veterinarian before use is advised to ensure it is appropriate for the dog's specific wound and health.
