Fabulous for my whippet

Wow 😮 l so pleased with it! It fits my whippet like a glove, l had a few different harnesses before and shouldn’t have waisted my money on them, so glad l decided to save up and buy the more expensive one

Great quality harness

This fits our Swiss shepherd perfectly. She is 7 months old , approximately 34kg and fits a L/XL on small settings so there is plenty of space for her to grow a bit more.
Fits really well, doesn't rub at all. The leash attachment on the front is a god send for when she is particularly overexcited and the handle is great for those times where she just needs a little extra help getting up/down.
Dries quickly after a swimming session, mud also brushes off easily once dry.
Couldn't be happier with this harness, well worth the extra money compared to other harnesses for the massive difference in quality.

LOVE this harness!

Such a great fit for our handsome whippet boy - easy to get on/off and the 3 different attach points are very useful for pulling or car seatbelt

Success at last!

I have a 6 yr old Italian Greyhound who startles at the slightest thing and backs out of her harness and bolts (luckily for home). This harness is truly escape proof, now we can safely enjoy walking together!

Best Harness Ever

Fit my Toller perfectly and has turned him into the best walker on a lead. The front attach and back attach encourage him to walk calmly and close to me, instead of pulling. The handle allows me to help him up over waves and easily grab him if he’s in any trouble. The back attach is also useful for clipping him into the car for safety. Best thing I have ever bought and I wish I’d gotten it sooner!

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!
