The burrs on the dog's foot pads are caused by the keratinization of the pads. If the dog has no abnormalities, there is no need to worry. You only need to clean the dog's pads regularly and apply hand cream or Vaseline. Parasites can also cause the dog's footpads to become keratinized and thickened, so it is best for owners to deworm their dogs regularly to avoid the breeding of bacteria or parasites, and try not to take their dogs to walk on uneven roads.
