This is the ultimate running leash. I've tried other products because I was looking to save money and they all fell short of what I needed. This is a heavy duty piece of equipment that fits comfortable and allows me to run with my dog hands free.

Wow, what a spectacular leash system. This is the only hands free system I will ever use. The design and feel of this system makes it a breeze to use. I give this product a four paw stamp of approval! Trust me this is the only system you will ever need for WALKS & RUNS!

I am very impressed with the quality of the product; it is exceptional. The belt width is especially nice in that, if my dogs pull, the wide width distributes the force so it's comfortable. I often put both dogs on leash and am also impressed at how they don't get tangled. The design is ingenious!

I have been using the Cardio Canine for almost 4 years now with my two Border Collies. I use the two leash set up and absolutely love it. The quality is superior to any other product out there and the customer service is phenomenal. If you have dogs, and you walk or run with them, this is a must have product.

I have had up to four dogs attached at one time and believe me that it is a great experience for all. The dogs go crazy when they see me grabbing their harnesses and head straight for the door. Highly recommend it and would love others to enjoy it so I won't be the only one that gets the strange looks from people when they pass by.

I won't run with my crazy dog, Addie the Border Collie, without the Cardio Canine. It allows my hands to have their normal range of motion and the leash attached to my waist helps me keep my balance. Even when Addie sees a squirrel, and pulls to one side I can still stay in control.

I LOVE MY CARDIO CANINE!!! Seriously I run with my dog Thunder all the time with it. We run in the Petroglyphs by my house and he loves it too! I've attached a picture of me and thunder on a run and I am pretty sure you can see the smile on his face too. Thank you for a fantastic product.

I like how durable the Cardio Canine is, made with high quality materials, and I appreciate all the thought that went into the design. The Cardio Canine leash has made my life easier and our runs far more enjoyable. I LOVE the Cardio Canine.

I was looking to invest in something I would use long term after my rehab. The Cardio Canine has been the best pet related purchase I've made in a long time. I now run with my big guy, Malone, by my side, and have added the second leash for his sister,  Zoe!

We took the Cardio Canine go for a test run and never looked back! The hands free running is GREAT and there is nothing better than knowing that no matter how obedient Ripley is, I will NEVER have to second guess his occasional need to TRY and chase after a rabbit or squirrel no the other side of the road with on coming traffic! I fully endorse this product and so does my running partner.

I bought it for my husband Matt who LOVES it! It's the only way he can run with our 2 dogs and 2 year old daughter. Before the Cardio Canine he had to choose between the dogs or the baby and when that happened no one was happy. We are very happy with our Cardio Canine.

Using my Cardio Canine lets me and my dogs get a workout at the same time. It's a great time saver and my dogs always enjoy our runs together.

I bought my Cardio Canine early in 2007 and am very happy to give it my strongest endorsement. As an engineer, I'm quite particular about product-design in many things that I buy. And I'm extremely impressed with how this product is both designed and manufactured. I would recommend the cardio canine without reservation!

I've had my Cardio Canine for over a year now and it was a great purchase. This product is comfortable and has useful pockets. It has allowed me to focus on my running rather than Howie and his leash. All in all a great purchase and I highly recommend it.

Cardio Canine is like a dream come true... my run, my dogs, free hands, total control, lots of fun... IT ROCKS!!!

I have been using the Cardio Canine leash for several years now and I love walking the dogs hands free. The leash is built very well-strong and durable and comfortable on my waist. I like the pouch attachment as that comes in handy for bags to pick up after them.

After months of struggling to get my chocolate lab to run with me, I finally found the solution... Cardio Canine. My lab is the best gift that I ever received and your system has not only given us the freedom to enjoy our evening runs, but I use it also to teach him to stay close to me in the yard!

Today I ran him for a full mile for the first time and it was great, especially with the cardio canine belt, it was easy and fun. I strongly suggest that you try this prodcut or buy it for someone you know who loves to run with their pet. Its better to run with 6 legs then it is with 2 ;) Happy running and keep those tails wagging.

I love just love this system. I can now run in comfort with my daschund for as long as we want. We run at least 7 miles every day and often up to 13 miles.

We finally had a chance to try the Cardio Canine... and both loved it! Frankly, I am amazed. What a great find. PS Buddy carries his walkman in the water bottle pouch. Another great feature!

I LOVE the Cardio Canine! Not only is the engineering of the product excellent, the quality of the product is unsurpassed. This is heavy-duty - your dog will not unclip and extremely comfortable. I can only say fantastic things about this product - I will use it every time I walk or run with my dogs.

I LOVE this product. It makes running w/my dogs so much more comfortable and easy. I've had other hands-free leashes, but none were as comfortable on my back as this one.

I am so happy to have Cardio Canine! I was so pleased to see the construction of the system and how the waist belt resembled the durability of a climbing harness

Cassie caught on very quickly that the circumstances had changed and didn't seem to mind at all running right next to me. She is at my side at street corners, the leash is right there if I need to keep her especially close to me. I don't need to use the choke collar anymore.

About 2 yr. ago I developed a problem with my foot, causing extreme pain in my toe, then numbness. The first day I ran hands free with Buddy, was incredible and fun and easy. We both had a tremendous run. I have been using the hands free device for the past few months and my foot is making a turn for the better

I have had the Cardio Canine Belt/Leash system for several months and I never walk the dog without it. I can drink my coffee while on our morning walks and it is no big deal when the cell phone rings since I have both hands free. I highly recommend this great dog walking product and never leave home without it!
