Before diving into treatment options, it's crucial to identify when your dog has a sore paw. Common signs include limping, favoring one paw over the others, reluctance to walk, licking or biting at the paw area, and swelling or redness. If you notice these symptoms, it’s important to examine your dog's paws closely. Look for any visible injuries, such as cuts, blisters, or foreign objects lodged between the pads.
