Many puppies are fond of playfully nipping at their owners' feet. This is especially common in herding breeds like Border Collies and Australian Cattle Dogs. When your puppy tries to nip at your feet, divert their attention to a favorite toy instead. You may keep this toy in your pocket for easy access. Just make sure that it is small enough to hide so that your pup does not jump up at you for the toy. Over time, your puppy should learn to divert their nipping needs to a chew toy rather than to your feet. Lastly, be fair and never punish your pup for biting your feet. Simply correct and redirect their behavior.
