Although it is tru that probably many dogs do that. I know BAsenjis definetly do it more often because i had never had a dog do that before. Ayo used to do that a lot and still does it if he is really "into" something and i pick him up. he doesnt mind being woken up though….I did with that the same as with the events of resource guarding at the begining, pay no attention and keep picking him up a lot all the time so he gets used to it. Usually the growl stays ata growl and doesnt escalate. I could tell becuause even when a few times he actually grabbed my arm with his mouth, he never actualy bit, he would leave it soft , like when they are playing. Sooooo, i just would not allow it to intimidate me and "forced " him to experience that a lot till he got used to it... These are the things that, as a new basenji owner ( and I know,.. that other dogs do that too, but like I said, to me my Basenji did it first), tend to freak you out. When he first growled, litteraly a few days after I got him, I was shocked, I thought, what did I get myself into?.. but then, once you deal with it, you realize that , those are the things, that make them so special, they have a very strong personality!!!
