How to care for a dog's torn paw pad
Look for signs of limping, licking, or bleeding.
If your dog suddenly is unwilling to put any weight on a particular foot or is excessively licking it, odds are he has a paw pad injury.
Examine the paw immediately when you see signs of discomfort.
Look all over the paw: between the toes, on top of the foot, and between the pads. Check for bleeding, cuts or abrasions, debris stuck in the pad, or a dangling dew claw.
