Hey guys I’m needing advice. I’ve read a lot here, but still unsure. Jax is 6 months old and we’ve had him since 7 wks. He’s never seen fighting or anything stressful. My issue is every time my dad or father-in-law stops by Jax barks constantly and his hair stands up in a straight line down his back. His tail is wagging while barking. He acts scared as he runs backwards while facing them. He’s seen dad several times now so he should be use to him. He does this to strangers, too. Does it seem like its anger or just a scared reaction. I’ll get a video this week. We’ve tried dad offering him his favorite treat, I’ll sit by dad and put my arm on his leg and dad always hugs me before leaving. I added a few pics of our boy.
