If your puppy bites your hand or chews on things, you should stop it in good time so that it knows that it must not overstep certain limits.
Experiences with biting in the first stage of life
From the age of 4 weeks, puppies start to become increasingly active and explore their environment. This also means that they show more and more interest in their siblings. They soon realise that it is great to pass the time with them. If they are not sleeping or eating, then playing with their brothers and sisters to the point of exhaustion is the order of the day. Chasing each other and playful fighting is particularly popular. And this does, of course, include the occasional bite. At first, puppies are not very strong and their teeth are just beginning to emerge. Soon, however, these teeth will be extremely sharp. Puppies experience this on their own body, but also get to know the reaction when they bite a sibling too hard. It will yelp and will most likely end the game for the time being. This can be extremely frustrating when you are in the mood to play. With time, puppies therefore learn to hold back and avoid the game being called off.
