I have previously looked after my sister's Border Collie. He had major issues with other dogs so I was used to walking him with a halti & lead in connection with also training him by squirting water at him as these were the few things my sister had tried that actually worked with him. I also had to make sure that he was lying down if he wanted a fuss made of him as he tried to jump up a lot and I also had to make sure he didn't get too giddy by making sure he got 2 hour long walks a day.
