Treatment varies with the injury to the pad in question. In mild cases, the paw is cleaned, wrapped in a comfort bandage and the animal is placed on antibiotics for 14 days. To alleviate pain anti-inflammatory drugs may be prescribed. Rimadyl® for dogs and Torbutrol® drops for cats.
If the pad has been lacerated, the pad can be sutured back together or surgical glue applied to bring the wound edges together. This often has to be done with a light sedative since the animal is in pain.
Animals may have the entire pad sheared off or burned such as with car accidents or cats jumping up on hot stoves. All you can do is debribe (clean out) dead tissue and try to create a healthy wound so that granulation can take hold. The animal's limb is bandaged plus antibiotics are prescribed for several weeks.
Wounds that are produced by irritating chemicals are treated to preserve as much pad tissue as possible. If the pad is completely destroyed or sheared off, it will not regrow since the cell type is totally different from surrounding skin.
