French paw licking may be caused by skin disease, interdigital inflammation, injury, or boredom. First, check whether there are any abnormalities in the dog's paws. If there are symptoms such as redness, swelling, scabs, dandruff, thickening of the cuticle, etc., you need to apply ointment to the dog's paws to avoid aggravation of the condition. If there is nothing abnormal, it may be that the dog is bored or washing his own feet, so don’t worry too much.
