First: any time he bite you scream loud, bite for dogs at young age is normal, but as owners we need to help them to calibrate the power of their bites, cause they play like that with their pack, but when you make them understand that they are hurting you, they will start to do it less strong, and the same time you scream show them a toy in exchange, so they understand that is with toys that he can play with you. Basenjis needs a lot of toys, especially as puppies, and a I mean “a lot of toys” and put them in a special place for them, like a toy chest, so they know where to find thinks to play with you, instead of your arm. But remenber make a big deal when he bite you, and is not yelled at them, no, cause basenjis you can’t talk to them in a bad way, is just scream like he hurt you so much, he will get it and I bet you that in no time if he continue to do it, he will doi it more softly.
