Does anyone else’s Cavapoo bark when new people come over?

We have a 6 month old Cavapoo and he’s always been weary of strangers. The problem is he barks like crazy when strangers (people he doesn’t know) come to our house. It takes him a long time to settle and stop barking.

Does anyone else’s Cavapoo do this? I wasn’t really expecting this behaviour with this breed, we are trying to train him but it’s rough because we don’t have a lot of strangers coming over.
