- Nicky M.Verified BuyerDog Weight 1-9 lbs4 minutes agoDog Weight 1-9 lbsReviewingActive Flex Dog Harness (XS/S), Shell XSRated 5 out of 5 starsCute, Comfortable & Great Quality
I love this harness! It’s super cute and looks even better in person. The material feels high quality, and I love how adjustable it is so I can get a really good fit on my pup. It feels secure without being bulky, and the hardware is really pretty too. We’ve been very happy with it and would definitely recommend!

The Active Flex Harness has quickly become part of our daily walk routine! The hands-free design is so convenient, but the standout feature is one I didn't know I needed: the handle. On a recent trail walk, we came across horse poop right in our path — and with Simba fresh from a bath, the handle let me guide him around the mess and keep him close until we were clear. Now I use it anytime I need him near me.
The dual clip options are a great bonus too — front chest clip for extra steering, back clip for relaxed strolls. Comfortable, secure fit, and the Fern color is gorgeous on him. Highly recommend for any pup parent who wants convenience without sacrificing control!

I’ve been really impressed with the new Active Harness. Finding a harness that fits our dachshund, Chef, can be tricky because a lot of styles feel bulky on him, but the streamlined strap design on this one gives him such a comfortable, secure fit without adding extra bulk. It’s also been perfect for everyday walks because it’s super easy to wipe clean and doesn’t hold onto dirt or odors the way some other harnesses do. It feels lightweight, functional, and just really easy to reach for every day.

This harness is a gorgeous bold pink color for our girl dog (who often gets mistaken for a boy), and we absolutely love how versatile it is! Having front and back D-rings, plus the safety handle is so great - for both off-leash adventures and busy city walks. It's super sturdy while also being comfortable and flexible when she runs around, it doesn't get caught in her fur or anything. Definitely one of our new favorites, highly recommend!

Penny usually pulls quite a bit on walks, so I was honestly shocked by the difference with the Active Flex Harness. The first time she wore it, she barely pulled at all. It gives me so much more control without feeling bulky or restrictive on her, and she still seems totally comfortable moving around in it. I also love how secure and adjustable it feels. This has quickly become our go to harness for everyday walks and longer adventures.

We absolutely love this harness! The fit is great on Jax and feels really secure without being restrictive. I especially love how the design gives him plenty of freedom of movement - he can walk, run, and play comfortably without the harness getting in his way. It’s also really easy to put on and adjust, which makes getting out the door for walks so much easier. The harness feels sturdy and well-made while still being lightweight and comfortable for him. We also LOVE the color - it looks so good on him, and we’ve gotten so many compliments on it while we’re out! Overall, it’s the perfect combination of comfort, functionality, and style, and we’ve been so happy with it!
