Your dog can get pad burns easily--anything from walking on a hot pavement or freshly poured asphalt or by coming in contact with chemicals. Pad burns should be treated immediately to prevent further damage to the tissue. Here's how to treat pad burns until you can get to the vet for further care.
If your dog's paws get burned, immediately put his feet in cold water for at least 10 minutes. You can use a bathtub or a simple pan as long as the whole paw is submerged. If your dog refuses to keep his paw submerged, wet a washcloth and keep it pressed firmly against his paw for 10 minutes.
After the pad has soaked, gently wash the pad with soap and water or betadine. Your dog's paw will be extra sensitive so be careful while doing this.
After you have thoroughly washed the pad, pat it dry with a towel. Do not rub the pad dry as this will only further irritate the skin.
Apply an antibiotic ointment such as neosporin to the pad. This will help it heal.
Cover the paw with a sock or gauze pads to prevent him from licking the burn.
Evaluate the pad burn. If it doesn't look like it's healing, take your dog to the vet.
