I'm just wondering! My guys don't wear a collar but if they are wearing a buckle, I have it fairly snug - two fingers can still fit but they can't pull out of them and I have control. The house I nanny at has a boxer and her collar is very loose - as in why bother putting the collar on the dog in the first place. She'll scratch and it'll come off, she'll get into something and I'll try to walk her away with her collar and she puts the brakes on and pops it off. Drives me crazy. And what's worse if she gets loose outside, she doesn't listen well at all and has started to check out the road (which is why I keep her on leash... oh that and she attacks the kids because it was cute when she wasn't full grown). So, loose or snug?
