Jackson has slipped out of a Puppia harness as well as a nylon step-in harness and an Easy Walk harness. It's not even like he tries but he has gotten out of all of these on 3 separate occasions lol. It's definitely possible and I couldn't have made these any tighter or he would have been suffocated lol. Step-ins seem to cause the most problems for us. But luckily, I'm not too worried about it as he has a great recall and I just don't pull on it a certain way now (like if he's behind me and I pull for him to come forward, that's when it's slipped over his head). I still use Puppia basically every day. I have the leather Choke-Free and he has been unable to escape out of that yet. I'd still like to re-try the Buddy Belt one day... I may have to make some altercations as it seemed one size was too big and one was too small so I couldn't find a good size for him.

I use a tie out at my moms house because there's no fence and 3 acres. But I never leave him out there alone. It's a 50 foot line so he has lots of space. But usually, I wouldn't call it a "tie out" because I'll either be holding the other end of the leash or letting it drag while we play fetch.

I think Jackson, at 16lbs, MAY be able to pull off walking on a collar. He doesn't pull and he's a bigger dog. However, I still don't take chances. And I'd never use one on a tieout, because if he were to see something and take off after it, SNAP, that's his neck. I'd rather is be a harness for a big OR small dog on any sort of tie out.

I think the OP is trying to do the best she can with what she has! I know I had never heard of putting harnesses on dogs before until joining YT. I walked Jackson on a collar for the first week I had him. It just didn't seem all that common or normal to me until I started going to dog events and dog parks and online forums, etc.
