Wouldn't it be great if your dog could have one harness that he/she can wear for everything? What if the same harness was almost impossible to back out of for escape artists? And what if it crash-tested to keep you and your dog safe in the car? And what if this harness was almost modular so you could remove some parts when they aren't needed? Well, this is the Ascension Extended harness and it does all of the above.

Paired with the Rescue Sling, this harness will even allow you to carry your dog if he/she was injured out in the wild.

People are asking

It's very simple. You simply need to pass the car seat belt through the harness and buckle it in the seat belt socket. Check out this short video.

Most likely yes. After testing the harness on more than 25 different breeds and shapes, we can say that the Ascension harness fits very well. But just to confirm, go to our sizing corner.

Definitely the side buckles. There's something so satisfying when you clip'em. Plus, each buckle can resist over 550kgf while weighting only 42 grams.

Good question! We investigated this topic as it was a concern for us. We are proud to say that the harness is better than its competitors at dissipating heat. Read the full blog here.

Not directly. It's hard to see on the pictures, but there is a webbing flap between the side buckles and your dog's skin. For the carabiners between the Extension and the Core Harness, they are elevated by the pad thickness so that they don't touch your dog's skin either.

Yes. Because the pads are airtight, you don't have to worry about water getting in there. Simply handwash the webbing with mild detergent and let it air dry.

Not on the harness. Velcro doesn't meet our standard for durability... But we get it, you need to attach your patches somewhere! That's why we came up with Velcro Sleeves that you can add or remove as you please. Check them out here.

Well, this Seat Belt Lock is designed to prevent the car seat belt from retracting back into the mechanism when your dog is secured in the car. Find how to use the seat belt lock here.

Dog attack

It’s been exactly a week since it happed. My dog and I had a dog run up on us and attack him. This harness is the only reason he didn’t run away and have the two Danes chase him down. As he isn’t a fighter this harness was the only reason I was able to pull him away. If this was one of his other harnesses he would have more then likely slipped out as he has a weird shaped chest and is so adjustable. But other then that makes me so happy and pleased to know while in the car he is safe buckled up and secured. He’s my weird little pretty boy who means the world to me. Always wanting to keep him safe but also comfortable. Thank you so much for creating this product.

Awesome harness

I rescued a Walker coonhound mix, she was abused for the first year of her life and spent the next year in the shelter. I started with generic harness’s and she would slip and attempt to slip then constantly out of fear of her surroundings when we would go on walks. I was scared to take her into the woods on hikes in case something would spook her and she would take off to places I couldn’t find her. I saw the accession harness online, and figured I’d try it. The harness was easy to adjust and fit her great and she couldn’t slip it because of the extra strap. We started hiking a lot more and she now does amazing anywhere we walk. We took the extra strap off and she still doesn’t attempt to slip the harness now. I walk her with it at least three times a day and she loves the harness. It doesn’t cause her to itch or have to scratch her back like generic harness’s do. The accession harness was truly the biggest game changer in training my rescue dog and would recommend it to anyone who needs a harness for their dog.
