Makes rides safe and enjoyable for everyone

Very easy to adjust straps to dog’s body. Very secure harness that adds piece of mind that should an accident happen, our dog will be safe. For a dog that loved walking around the car while his owners were driving, he immediately adapted to the harness and still loves riding around town just as much!

5 stars

Our dog has severe car anxiety. We used to bring a large metal crate for her to travel in but it took up too much space. We bought her a soft sided kennel, she ate through it. Then we just put her bed in the car but she would wander all over the back of the car during our monthly three hour ride. Tried this harness today with her bed in the back. She never made a peep. She was safe, we were safe, it was great! We used it with the dirt bag seat cover. It was not too hard to adjust the harness to fit her comfortable and to buckle her in through the opening in the seat cover. We left her collar on so had no problems with how to walk her if we got her out along the way.

Safe, Secure, and Sound!

If seatbelts are the law for us why not for our beloved Phoebe? After researching what type of harness would be the best for our beloved little one we discovered Ruffwear was the one for us. The "how to" video is a "must watch” for correct fitting and placement. We have not had any issues when buckling in for a trip - her safety is a priority for us. Phoebe seems a lot more calm when the harness is on her which is an added benefit! Thanks for making a high quality product that looks smart for dog and vehicle.

Love this seatbelt harness!

I have always known the importance of buckling up your pup in a moving vehicle, but before using this harness, I just used a normal harness with one of those seatbelt attachments. However, the seatbelt attachment would often come undone and the harness wasn’t protecting my pup in the right places in the event of an accident. So, I decided to get a proper seatbelt harness, and since Ruffwear always makes the best and highest quality items, I went with theirs. Luckily, we haven’t had an accident so far, but I can tell this harness is the real deal. It uses your car’s actual seatbelt to secure your pup, which is much safer than a seat belt buckle attachment. The harness is padded and covers all of the right areas, and it all secures tightly and nicely. Some people freak out that it’s too difficult to put on every time, but that is not the case. The first time, you do need to adjust it properly to your dog’s shape and size, but after that time, all you need to do is slip it over their head, secure the harness on each side, and buckle them in with your car’s existing seatbelt. I feel that my dog is safe and protected while wearing this harness, and we try to use it every single time he goes into our car. Next time you’re wondering whether you should buckle up your dog, just think—you’d buckle up your baby or toddler too right?

Glad for the Safety it Provides

The harness was easy to fit on our Annie and she readily accepted wearing it in the car the first time out. The only reason for 4 stars it because at first I found it awkward to clip into the seat belt. Overall, we are very happy with the harness.
