Nipping or Biting
Most puppies do lots of nipping, biting and mouthing because they are “teething”. It feels good to sink their tiny little teeth into almost everything in sight, including the hands and arms of their beloved human family.
The most frequent solution is to train the puppy in “bite inhibition” or how to use a “soft mouth” with people.
In the “natural world” this is actually done within litters of puppies who let out a serious “yip” or “yelp” when another puppy happens to bite too hard.
You too can do the exact same thing to stop biting from occurring.
What you need to do is wait for a time when the puppy applies too much pressure with their teeth and then startle them with a vocalization similar to a yelp. Then withdraw your hands and don’t play for a while.
This is exactly what other puppies would do and your puppy will be left to assess the information and learn the lesson that biting hard equals no friends.
If the puppy refuses to train where mouthing and biting are concerned you may need to consider some shock techniques. Many experts recommend the purchase of a safe anti-chewing spray that you apply to your hands and this makes the puppy associate human skin with horrible tastes. This is often a last resort, but can really work wonders on a particularly tough puppy.
