I've had several harnesses for my year old Lab mix. She could get out of them by backing up. This harness is wonderful. She can't get out of it, and it fits her well. I originally was going to cancel my order, thinking it was just like other harnesses. I'm so glad I didn't. Well worth the cost.
I love this harness for our very active dog! She was always tugging at the "choke collar" lead that my husband prefers (I do not), so this is a phenomenal improvement over that! She's happy to put it on, happy to go outside, even sleeps with it on when I forget to remove it at night (she's such a good dog!). Would definitely recommend/purchase again.
