The Original Sense-ation No-Pull Dog Training Harness (Blue, Medium-Large Narrow)

Hard to imagine, as he turns 7 months old, we started out with the X-S when he was 19 lbs, now he's officially 7 months and half grown and 62 lbs and we're wearing a medium-large. As usual, the design is made for normal shaped dogs, not deep chested narrow sighthounds, but it works. When we're at home I take it off when we're inside and overnight, but when he comes to work it's on probably 14 hours a day and with the last size as he was approaching growing out of it he did get some erythema of his arm pits from it (it's not supposed to be on all day). It's durable, it will fuzz/fray with a few minutes of puppy chewing so they have to be monitored or have it off. We'll see how long this size lasts and if we eventually completely grow out of this product at some point. Hardware is good, clip is always a little finicky and plastic but I haven't had one break, even when getting stepped on, thrown, and abused.

Had a horrible time trying to find a harness that would fit my dog correctly. We even had assistance in pet stores and never found one that worked well.My dog is part poodle and has a very narrow chest. The other harnesses did not adjust and keep the front strap where it should be.A friend told me about the SENSE-able harness. When I checked it out, I decided to try the SENSE-ation model.It adjusted quickly and easily. It fits correctly and the front strap stays in place without pulling the belly strap into his armpits.It has worked well for us. So easy to put on and keeps him from pulling on his lead.
