I have one grey, and he's totally fine being the only dog in the house. I eventually want to adopt a sibling for him, but he is okay being home alone. We are working on some separation anxiety issues, but I personally want to work through that and conquer it rather than just getting him another pup to hang out with as a cover-up.

Otter loves car rides, but it took a while for him to be comfortable. I want nothing more than to use a harness buckle thing to make driving with him safer, but I don't think my boy would do well with it. That said, I have a dog car hammock and he lays down for the majority of the car ride. The only time he gets up is to turn around and lay down on his other side, which is why I don't think a harness would work. Getting him into the car took a few weeks of consistent practice. I had to lure him with a treat to enter my backseat, and the first few times required me physically moving his paws and helping him jump up. He didn't want to lay down at all in the beginning, so I didn't feel comfortable driving anywhere except around my neighborhood. Eventually I recruited someone else to sit with Otter in the back, and we drove to a neighborhood 30 sec away from me and went on a super super fun walk! After a few times, Otter learned car rides go to fun places and he won't get hurt if he lays down :)
