Happy dogs, happy owner

Well fitting harnesses that have the 'Houdini' Whippets firmly secured while on their daily walks.

Best harness for our whippet

This harness has good underside support and is doesn't cover too much of our whippet so good for summer as well. We can lift our whippet briefly in this harness using the handle.

The only style of harness I would use for a whippet

Fantastic fit, no rubbing under the elbows, third strap so there is no way a whippet can back out of it when correctly adjusted which they can easily do with a two point harness. I purchased this as my girl has a neck injury & I wanted to prevent and sudden jolts to her neck if she tried to take off after a kangaroo/rabbit. Love it!

Flagline dog harness

Great product and service thank you


Love this harness for my whippet. Lots of adjustment so I can get just the right fit on the little guy. Seems comfy for him. Easy on and off. Makes me feel better knowing he’ll have a very hard time getting out of it whilst walking.
Great service, delivery was quick. Thanks.

Best harness!

I bought my 33kg greyhound this harness in medium. I absolutely love it! He looks so comfy and happy in it. I love that it doesn’t move around when the lead pulls a little tighter when he’s stretching to sniff something. The handle helps keep him close in tricky situations too ☺️ Highly recommend this harness!

Perfect for large greyhounds - I Have A New Boy!!

Jack my large 38kg greyhound, would plod along his walks but not now… he trots, with his ears pricked up and a big smile on his face 😆

The other (expensive and researched) harness just wasn’t comfortable for him and it showed. I now feel bad bc I realise how happy he is now he is in a properly fitting, quality harness that is the correct length for a greyhound’s body. The six adjustments on the harness let’s you find the perfect fit for our skinny, long bodied, deep barrelled, and yet oh so delicate skinned bubba’s …. Honestly, it could have been designed for them.

Definitely worth the money, best thing I have ever bought him.

The best I’ve ever found!

Love this harness and cannot recommend highly enough. My 10 month old English springer spaniel has been an escape artist since day 1, and once she realised she could back out of a harness there was no stopping her trying it. The Ruffwear harness gave me confidence that she couldn’t get away on me, and she will stay safe which is so important. I don’t know what I would have done without it! This is my upgrade to the larger size in the Flagline from the Webmaster (that I still use because it’s great!) however the Flagline offers me the front attachment for when she pulls on the way to the park. Very hard wearing, she goes swimming in them and I can just hose them off and hang out to dry when they are dirty. Will never buy another brand, these are it! Thank you Ruffwear!

Best harness

I bought a flag line harness for my collie male who can escape from his car harness. This harness fits him beautifully in medium, he has not escaped and he seems happy and comfortable in it. So much so I have ordered another one for my new puppy.
