Hard figure out

I am getting used to this harness but it is not intuitive. And getting on and adjusting with wiggly puppy in beginning it’s easy. I clicker trained her to put head through opening. The side buckles take some patience.

Dependable Safety

To start off, my dog hates car rides. She shakes, whines, tries to climb in the front seat and is only slightly calmed by pop music (don't ask). My wife and I got this harness to protect ourselves and the dog after a few hairy incidents where she tried to climb in the front seat while driving at highway speeds. The harness arrived and the fit instructions were simple to follow. We got her harnessed up and then took her for a ride. We found the center rear seat works best and she can move some but also be secure. The harness allows the seat belt through the attachment strap and it works great. We unfortunately had an almost immediate test when I had to stop short for another car not paying attention in a supermarket parking lot...The harness worked great, kept the dog from falling into the foot well and kept her secured. The dog also seems to be more confident in the car when strapped in. The only downsides to this product are that it is not meant for walking. There are no leash hookups so there is a bit of juggling her regular harness and her car harness when we get to a rest area or our destination. This can be a hassle, especially on short trips but we found a work around with her old harness that can fit over the Load up harness for short pit stops. Good solid product, thank you!

Fantastic Harness!

We’ve been using the Load Up Harness for a few months now and want to let everyone know what we think of it~ This item was purchased to keep my Queensland Heeler safe while riding in the backseat of my truck. We have travelled full time since I picked her up as a puppy and as she grew I experimented with a variety of harness styles. By far, the Load Up is superior... my dog is comfortable in it for short or long periods of time. I especially appreciate that it is extremely adjustible while still providing excellent coverage for her safety. Of note; Do follow the sizing guideline!!! Purchase the smaller size if your dog is an in between measurement!!! I did and it is perfect, and it does have a reasonable amount of adjustment options. The Ruffwear products are now my only consideration when shopping for such items for my road companion.

Bomber Harness

After watching your crash test demo I decided to be a responsible dog mom and buy my fur baby a seatbelt. Once you get it adjusted properly, is easy to put on and attach into the car. Though this harness is a little on the heavy side for a 7lbs dog, it looks to be more durable than my climbing harness and I can drive feeling that my dog will be safe in the case of an accident.

Excellent quality harness

The quality of the harness is great and it fits my dog perfectly. Sawyer comes on a lot of car trips with me and I have been looking for a good quality harness for her to strap her into her seat so she stays safe. I use it on a daily basis when she rides to and from work with me. We also use it on longer car rides for vacation. It is comfortable enough that she can sit or lie down in the seat but she cannot move out of the seat so she is safe. I highly recommend this harness.
