Amazing harness!

After much research, I decided to order the Load Up restraint harnesses for my girls. I was worried about safety first, as well fit and durability. The Load Up fit the bill. It’s perfect and comfortable. My girls get so excited when I get them out. My girls are so comfortable when riding in the truck now and they’re perfectly safe. I’m so glad I got these harnesses for them!

Don't Get In the Car Without the Load Up Harness

Easily adjustable. Quick to put and comfortable. Provides stability from fast stops and sharp turns. Allie enjoys wearing a safety harness. It provides her a real sense of security. Not to mention that it also makes me feel better knowing she is protected from an ejection or violent crash. It is instantly usable in any vehicle that has safety belts. We don't leave home without it... never.

complicated but good

I found it hard to adjust the straps and actually figure out how to adjust the harness and put it on my dog. I had to use the videos on Ruffwear's website, thank you for those. Once it was all figured out it fit my dog really good and she seems to be comfortable in it.

Would Recommend

This is a great harness for us, but likely wouldn’t work for dogs who move in the car. We have the Ruffwear car hammock and love it, but in advance of a recent long road trip, started thinking more about safety. We never thought much about a dog being ejected from the vehicle or being tossed in the vehicle during an accident. On our second day of acclimating/desensitizing our pup to the harness in advance of our road trip, someone turned in front of us and we slammed on the breaks and she absolutely would have hit the seat in front if she wasn’t restrained in this harness. We use it for every car ride now. We still use the hammock for when we do leave her in the car (in cool temps only). I did not give this five stars for two reasons, one is that our dog is longer in body length (think daschund or corgi but she’s 36 lbs), so the attachment loop does not sit low on her. Because of this, she gets easily tangled. Fortunately that is only when we park and she pops up. She lays sideways the rest of the time in the car. Secondly, it is difficult to get the harness adjusted correctly, the head opening is super snug, and there isn’t anyway to use this with a lead (which I assume is intentional so it doesn’t get worn out) so it is an extra piece of pup gear and a bit of a pain to transition from car to the world. However, we are so glad to be able to afford this for our pups safety and that of our passengers. Ruffwear seems to be a great company,too!

Load Up Dog Car Harness

I purchased 2 of these, a small for my malinois puppy(50 lbs) and a large for my senior rottweiler (95 lbs). They were already behaved in the car with staying in the back, but I wanted them to stay in one seat and not fall out the seat if I have to stop suddenly. This harness is great at keeping them both seated and secured for the whole ride. They can comfortably sit, stand and lay in their seat. I have not had any problems with them becoming tangled in the seatbelt as I lock the belt in place like I would for a carseat. They can even wear the harness all day without damage to their skin and fur. The harness is easy to adjust and put on and off. I was able to teach everyone in the house how to use the harness properly. I do not have anything negative to say about the harnesses at this time. Overall I am very pleased with this harness!
