Hi, I can help you with your question today.
Paw pads are notoriously difficult to heal since the dog is consistently bearing weight on the surface, disrupting the healing process.
I recommend washing the area thoroughly with mild soap and water.
After that, apply a thin layer of New Skin (liquid bandage). This may sting for a short time. The liquid bandage will harden and protect the wound from dirt and infection.
If the wound is small enough, the New Skin may even act as skin glue to keep the edges together and promote healing.
Please let me know if I can answer further questions. I am happy to continue until I provide the service that you seek.
