Has anyone ever experienced dog legs "popping out" of some of these no-pull harnesses? I have a client with a French bulldog who popped out of hers all the time until we decided it wasn't worth risking anymore. We just couldn't seem to get it to fit well. To make it tight enough so her leg couldn't pop out, it just seemed too tight and uncomfortable for her.
Another client I have with a Dachshund puller uses this harness, and I think it's great:

The Sherpa sleeves are really comfortable. She tried this one after the others didn't work for her, and it's really stopped the dog pulling - which was essential since she's just had surgery for carpal tunnel (I also suggested a shock absorbing leash which is working out great too).
