It took my DH over 3 months for Chloe to go anywhere near him. He would approach her on his knees, literally. She would lie in her crate, door off and he would take his lap top and sit outside of her crate and just hang out. he would give her a small treat or 2 while he sat on the floor, sometimes he would read and after a while she started coming to him.
Fast forward to 4 years later and this crazy BIOTCH is all over him!!!! Give it time. let himn feed her and give her the things she loves most.
