@margiem I think you are right, over the few days I've noticed that it was only directed towards men and not just in the couch 'situation'... My son's friend came over and she growled and snapped at him while all the kids were playing together and he just wanted to pet her. Then just sitting here, working on my computer, Shelby lying next to me and handy man comes to the door. When I open the door she is there with me and alert as if she is ready to protect me but yes I agree and that's what I do is I reinforce her good behaviour and I f'course she is stressed. New family, new rules, new everything. She is really testing her boundaries and finding her place in our clan Also another thing is those house accidents and jumping on tables and kitchen benches makes it more difficult. But definitely something to do with men. Looks like she is a quick learner at lease for now she gets "no", she learned "sit"...slowly getting there.

@eeeefarm We already got a crate and in the processes of booking a behaviourist. No, it was not impulsive but I never dealt with basenjis before, we had a lab prior to her. We read quite a bit about the basenjis and we knew that we wanted to adopt that specific breed. I had numerous communications with the breeder and she told me that she was the most sweetest girl ever and very well behaved. I tries to find out as much as possible about her before we got her. I just did not realise she was not a house dog at all... only when she was a pup. But now we know, breeder also suggested to get a crate and was very surprised of her behaviour. We took the advice and maintaining very firm voice when she is like that and it seems to be working. She just went crazy in the house - jumping on tables and kitchen benches, so we are slowly and patiently putting her down with a no, or if it does not work outside for some time. I can see that she learning the rules. It's just hard for her - all these changes that just happened. She bit my husband today but he managed to take her and get her outside with a strong "no". Thank you for sharing that your 3-year old boy bit her on your first day! It's reassuring that we are going to get there too one day:) I am sure we will. It also turned out that she was house trained when she was a pup and then lived outside, so we get minor accidents from time to time... Thanks for all your help, guys!

Thank you for all your feedback! Yes, it seems like she is very fond of her and was claiming her right... We'll try having a lead on her. We don't have a crate for her as we just got her a day ago. we adopted her from a breeder but from what I know she lived outside and was not a house dog at all.
I agree she might need some training...

Hi, really looking for some advise...we just got a 1-year old basenji female. And she suddenly started growling in the evening when my son stood up from the couch while she was on the opposite couch sleeping with my 8-year old. Then my husband tried to take my daughter to sleep and she started growling again and bit him. We are very sad and not sure how should we go about this! Please help! Then I came along and in a very strict voice said "no", and took my daughter by hand and walked her to her bedroom. Shelby (the basenji) followed her and positioned herself right next to her, on her bed.
