Jackson is 16lbs and pretty muscular, but I'd personally never walk him with a collar. I have tried it in the past for quick potty breaks but even if he slightly tugs, it irritates his throat. He's not a puller and well-trained on the leash... but I don't know, I still just prefer a harness. So I very rarely will attach a leash to his collar, because he also got out of a collar once! Yikes! Sometimes for pictures, I will put it on his collar so I don't have the harness in the pic (LOL) ...But anyways, yep, I like to keep Jackson's a bit looser just for comfort since I'm not using it to walk him with.
