Do this to calm the puppy down
Puppies being mischievous is nothing new and it's part of their development. It is important that you give your puppy plenty of freedom to run off their energy and have the opportunity to chew, tear, dig and do other things that your puppy needs. Sometimes, however, the puppy can get "puppy night" which is often a case of the puppy being overtired and needing help to settle down. Puppy fever is very common and in most cases grows out of it with age.
Why does the puppy bite me?
One reason why a puppy bites is because its teeth are itchy or painful. To help your puppy, you can give it something to bite on, such as a chew bone. In many cases, leaving the puppy alone or even ignoring the puppy will help it to settle down.
How to calm your puppy
You can also try putting the puppy down between your legs and gently rubbing the chest and muzzle. This exercise takes time and it's not easy for all puppies to sit still. To help the puppy, while you are massaging the puppy, you can calmly hold it and then when the puppy stops struggling, you can reward by releasing the puppy. Once you have been doing this exercise for a while, the puppy will learn that it can get loose when it is not straining.
It is common for puppies to come up for air in the evening, when they are tired. The puppy may then need to get rid of some excess energy and it can often help to let weapons play off a little. It's good for the puppy to have a designated place in the home where it can relax. Take the puppy to the spot and talk quietly, while petting the puppy slowly and gently. You can also use a chewing bone for occupation, if the puppy is having difficulty settling down.
