    LOVE

    My 3 yr old, 60 lb with some issues, loves this harness. He used to bite when putting on his old harness. He stands calmly when this harness is being put on. 😊 the harness is like a little hug to him.

    The best harness for our hyper Maltese

    We have used the Flagline harness for Murphy for 4 yrs (he's 6). It's secure & the handle allows me to lift him quickly when a large dog approaches (he doesn't like most large dogs). He also likes to shimmy out of his harness but the Flagline makes it challenging to do so. I can't say enough good things about this wonderful harness 🐾👍❤️.

    Lightweight, secure, and durable!

    For size reference, I got an extra small for my 19lb Smooth Fox Terrier. I just received this harness about a week ago and it's already one of my favorite pieces of gear I own for my dogs! I've been searching for a harness for my Smooth Fox Terrier that was lightweight and not bulky due to his gear sensitivity, secure and escape-proof to ease my anxieties, and durable enough to handle his daily shenanigans. This harness hits all of those marks! It's very secure yet light and comfortable for him unlike a lot of harnesses I've tried. It also doesn't choke him if he pulls in it, which is a plus! I love the three leash attachment points, the two closer to the neck are great for when I need a little more control, and the one at the tail-end is perfect for giving him more freedom when I don't need to micro-manage him. 10/10 would recommend above all other harnesses, it's worth the price!

    Escape proof!

    I have owned this harness since 2024 and highly recommend it! My dog can get spooked and has escaped from other harnesses we had tried in the past. I love the handle if I need to grab her before crossing an intersection and it's very easy to rinse off.

    Comfort without Escaping

    Our dog can back out of two-strap harnesses in seconds, so I wanted to try a three-strap harness. It's been great! The third strap is kept relatively loose on his body for comfort, but it's still quite a bit smaller than the second strap, so it keeps him in the harness when he tries his back-out moves. The neck strap is still easy to slip over his head. I also like that there is ample space between the two front straps for leg movement. The harness is lightweight and pretty thin, but the fabric is strong and holding up just fine. It's similar to the ripstop which my old backpack is made from, so I'm pretty sure it'll be durable too (I wash it in cold water and don't hang it up in direct sunlight), but only time can tell. The front panel distributes the force of occasional pulls far better than any collar and I appreciate that there's a handle.
