Great product. We have one for all three of our dogs and it’s the only one we have used that they cannot escape from. Looks great and easy to use.

Great harness for my GSD

My 6 year old GSD enjoys his new harness for routine daily walks.

Fast Delivery and Good Quality Gear

This harness fits amazingly and in super lightweight. Easy to wash down all that dirt and sand off from those little adventures and feels good quality. Rav, our Kelpie x Border Collie loves it!! In fact she wore it camping all weekend. Super handy carry handle on top, and multiple tie off points for leashes.

These harnesses are well worth the money

We have had several previous harnesses for our whippets, but because of their large chests they can easily slip out the back of them. Having the waist band is safer. The harnesses are also more comfortable because they don't cut under their front legs. Frankie in the photo is wearing a small size as she is a puppy. She looks like she is about to parachute over enemy lines.

Really great product, helps our dog not pull on the lead when connecting to the front, and easy to pack into a small bag when going on trips. would definitely recommend!

So good Sadie hasnt been able to escape from this harness. 10 out 10 thank you

Best Harness on the Market by far!

Kona our 5month old Whippet prefers harnesses over collars, and yes we did try numerous collar types - martingale etc. When we switched to a harness we found Kona stopped pulling, and much happier on walks - but after a while we found the straps rubbed on long walks, we tried others in pet stores without luck and then found ‘Canine Spirit’ and Ruffwear harnesses. We went with the Flagline as it’s lightweight, x6 points of adjustment so it fits really well around Whippets chests! The handle is really helpful for getting in/out of the car, over obstacles etc.

The standout feature must be the adjustability. We sized Kona for a size that just fits (Small), little loose around the edges but after two weeks he’s filled it out and it fits perfectly. Ruffwear harnesses are absolute top quality, and I know that Kona will get years of use out of this one, because as he grows up/out/chest down we can tailor each area to fit perfectly via the x6 points of adjustment.

Compared to harnesses in general pet stores, yes Ruffwear are pricey, but... buy cheap buy twice! I’ve always been told.
