Your Schnauzer is a biter. They bite during games and nip at your heels when they want their dinner. You mostly ignore the behavior, until one day, your pup nips at the wrong person. Suddenly, your friends are upset and don't want to hang out with your Schnauzer anymore. You need a solution. Training your Schnauzer to not bite is an important part of raising a well-behaved dog.
There are many reasons why a dog would naturally bite. Excitement, anxiety, and unfamiliar situations all bring out a Schnauzer's natural instincts. In addition, your pup may be biting because you have accidentally trained him to bite in certain situations. Dogs quickly learn how to get the results they want, so if biting worked in the past, they will try it again. You can train a Schnauzer not to bite at almost any age, though it is easiest with young puppies. The training process will require firm rules and consistent enforcement. Make sure everyone who interacts with your Schnauzer is on-board for the new 'no biting' rules.
Two helpful tools for training your Schnauzer not to bite are toys and rawhide bones. They can serve as a substitute chew toy when your pup decides to nibble on your figures. If biting becomes severe, you can use a spray bottle filled with water as a deterrent. Keep in mind that your Schnauzer will not learn to stop biting overnight. Patience and consistency are required to help your dog, whatever their age, understand that biting is not an option.
