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!

Load up Harness

I have been quite happy with the load-up Harness. It is easy to get on. My only issue with it, is that the harness clips are hard to unbuckle (buckling is actually easier) even when the dog is not moving. But for putting the seat belt on/off it is great, much better than the one I had before and although I can’t ask her, I think my dog finds the harness itself is more comfortable.

Great quality, easy to use, seemingly comfortable for my dog, and seems that it will last for a long time! Have been recommending it

I feel so much better knowing my dog is safe.

Using the video to help, it took a little to adjust the harness to my dog but once I figured it out, it was easier. I feel so much happier now using the actual seatbelt. The one I had previously was never going to help in a crash. Ruffwear is so good. With this harness, I know my dog is safe and I highly reccomend it to everyone.
