There could be any number of reasons your dog may be experiencing swollen paws, also known as pododermatitis. Dog paws are more sensitive than you might expect and can be irritated by something as simple as a pebble getting stuck between their toe pads. It’s a good idea to check your pup’s paws after going for a walk to make sure there’s no debris causing them problems.
Other causes of dog pododermatitis can range from simple overuse (like when your feet get sore from a long walk) or from spending too much time on irritating surfaces, such as hot asphalt in summer.
