Real Stories, Real Impact

"When I found Optimus Gear, I decided to try their harness. One day, someone almost merged into me on the highway, and I had to slam on my brakes. Thanks to the Optimus Gear harness, my dog stayed secure, avoiding injury, and I was able to regain control. This harness saved my dog and me. It’s a small price to pay compared to vet bills, the life of my dog, or a lifetime disability." - Amanda

Great fit

It’s a great fit on my 110 lb Rottie. She wears it readily - knowing a car ride is in the works .,.

We bought this in the summer, but recently started using it exclusively both as a seatbelt and harness to walk. The quality is excellent and I feel like my puppy is much safer in the car when securely in place with this harness. We will definitely look to purchase again when we add to our pack.

Thank you so much for your kind review! We are so happy that you're able to use it for all of your daily activities!

Highest quality

Every now and then you buy something that impresses you. This system is so well thought out and is such good quality. The hardware is all very similar to what we used in the aviation industry .

Optimus Gear Dog Harness

We purchased a blue, medium harness with seatbelt attachments and we couldn’t be happier with our choice of this product. We attended a pet expo near our home and found this product being displayed. We had hoped such a product would be promoted at this event and we were delighted to find it there. Thank you Optimus Gear for making car trips safer for our dog and worry free for us.

Thank you so much for your kind review tim! It was a pleasure to meet you guys at the expo and we are so happy to be a part of your safety journey! Keep us posted on all of your fun adventures! Safe travels!
