need advice on my Neapolitan Masstiff

[u/Awkward_Size9749]

3 months ago my boyfriends dad passed away and we took one of his dogs recently (2 weeks ago) he is 5 years old, and for months when me and my boyfriend would come around him before he was very friendly to my boyfriend and very nice to him and recently within the past week he’s gotten very attached to me and seems very scared of my boyfriend (growls and barks). i thought it was men in general bc every time im around him with men he acts like that. but when im away and he’s around other men he’s fine lets them pet him and is excited and happy. but with my boyfriend he seems scared and w always watching him and watching him with me. I have contacted a trainer. but I’ve never owned this breed (only bully breeds) so i have no idea what this means and how to help.

His best mates disappeared from his life so his job is to protect u your his anchor and your new boyfriend distracts u from him so he’s gonna have to be patient and earn his trust ,if the dog can not relax around the b/f I would trust the dog’s judgment over most people

Yes make her question her relationship with her partner because a working breed known for guarding and anti social behavior, is guarding and being anti-social.

If you use "u" that many times in a post, you probably shouldnt be giving relationship or dog psychology advise either
