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.

Excellent Harness

I now have two of these harnesses! They are great for safety while traveling. Once my puppy is old enough, I’ll get a third one for him. They are perfect as an all-purpose harness when traveling as well. Great product, well-made and durable.

Great Product - A MUST Buy

It took a while to get it properly fitted to my dog and for my dog to adjust to it but once we got it all set its been great ever since. The harness is easy to put on and quick to attach. It looks good on so when we run errands and have to get in and out of the car I don't mind leaving it on him. Most of all I love the peace of mind it gives! I know he's safer being tied down and I know I'm safer without the risk of him hitting me in case of an accident!
