Our Experience With the Julius K9 Speed Harness

We have been saying for quite a while that our pack of pitties could use some extra exercise time to get out their energy and in the case of our sweet girl, Bella, lose a few pounds. Bella is a couch potato when she is inside, but as soon as she goes out, she is ready to find the nearest escape. Needless to say, when we take her out, her being secure and unable to escape is of paramount importance.

As soon as we unboxed the harness (and human speed belt), we knew that we finally had a harness system that would give Bella that free-running feeling and give us peace of mind knowing that we could keep her secure and escape-free. The material was sturdy and getting it adjusted was a breeze. Bella did not fight to have this harness put on and now stands waiting in excitement to be harnessed for her daily jog.

We have been using the Julius K9 Speed Harness for several weeks now and can say it has not shown wear and tear and is easy to clean. The buckles are sturdy and I do not worry about them snapping off like several past harnesses our pack has used. Although we only go out during the day, I still appreciate the reflective material for added visibility. We did add the speed belt accessory and it is perfect for holding phones, dog treats, and human snacks.

We cannot recommend the Julius K9 Speed Harness enough. We do not foresee it wearing out anytime soon. We also love how comfy Bella is when using it. We are planning on getting a second one for our other pittie packmates so they can adventure together.


In conclusion, the Julius K9 Speed Harness is an extremely well-designed and crafted harness for dogs and humans who are looking for that extra sense of adventure. It is highly adjustable and made of durable materials that will last for mile after mile. It is available in sizes to suit all pups and comes with a one-year warranty. While it is at a higher price point than similar harnesses, we believe it is still a great value. With two thumbs and four paws up, we can say to run, not walk to get your Julius K9 Speed Harness today.
