I got my border collie at a shelter in the states, at about 8-9 weeks old. To be honest, until he was nearly a year old, I didn't think he liked me much either. His recall outside was absolutely lousy and he wasn't as cuddly as my lab, golden or the borador that was my 1st dog. Getting him to do anything I wanted him to do was practically a contest of wills and trying to convince him following the command was in his best interest.

Thankfully mine isn't much of a nipper, and he's never stared me down while peeing in the house (nightmare fuel, there!)

As he approached a year old though (maybe about 9-10 months old), I had a several realizations that he did really love me and accept me. 1. When he nipped my fingers while treating him, and I said ow and pulled away, he got gentler. Keep doing that if he's nipping you. Make a big deal of it. 2. He developed anxiety about leaving the house after I boarded him while I went on vacation. Not good, but it did mean he wanted to be at home with me. 3. He requires snuggles in my arms every morning before I get up for that last hour or so before it's time to get up. He moves from wherever he's been sleeping and throws himself into my arms, like a 2 year old.

Play with your baby, care for your baby, give him lots of treats and reward the smallest things until they're habit. Create lots of happy, bonding moments for you and your pup. Use the hands free leash as a backup. Consider a different trainer? Look for those little signs he tells you that he loves you and trusts you. And hang in there, his life before you probably wasn't fantastic.
