I have a 5 months old puppy and Ilove him but he really likes biting me. I don’t know if it’s just him being playful or being aggressive. How can I teach him not to do that?

Congratulations on your new puppy! It takes some time for puppies to learn to mind their manners. I recommend making sure that Percy has plenty of toys to chew on as his adult teeth are coming in. As you are playing with Percy and he starts biting, you should stop playing and tell Percy "no" and only begin paying attention to him again once he is calm. I hope this helps and am happy to answer any other questions you may have about Percy!
