How is the dog's paw rough?

It's normal for dogs to have rough soles. Just as walking without shoes hurts, dogs hate wearing shoes (most of them). So it's equivalent to their shoes, which can resist friction. At the same time, you may think there are many, but this only changes with age and walking distance. Don't worry! However, it should also be noted that when the ground is too hot, it will cause harm to the soles of dogs. Try to take him out as little as possible!
