How to measure your dog
Snugly wrap your soft measuring tape around the circumference of your dog's rib cage, just behind the front legs. To see this in action, check our girth measurement guide video.
How to Find Your Size
Use our Harness Finder to find a recommended size of PerfectFit Harness. This option is ideal for fully grown & non-mixed breed dogs.
If your dog is a mixed breed, still growing, between sizes, or has a unique shape, contact our team of sizing experts. Send us:
- Your dog's girth measurement
- Clear photos of your dog (side view & from above)
- Your dog's breed or mix of breeds
- Whether your dog pulls on the lead
- Your dog's age and weight (if known)
Pulling
For strong pullers, we choose a wider harness to distribute force more evenly, maximizing comfort. While not an anti-pull device, the PerfectFit can significantly improve pulling behaviours.

What comes in the selected harness set?
Top piece
Sits across the top of the shoulders on your dog's back to allow full freedom of movement and a comfortable, secure fit.
Front piece
Sits on your dog's breast plate, down the chest to help prevent twisting and keep the harness balanced and stable.
Girth piece
Wraps around the ribcage to provide security, adjustability, and a snug, escape-resistant fit.
Base piece
A front and girth combined into one piece, which sits on the breast plate & runs around the rib cage of your dog.
Jasper and I both love his Perfect Fit harness. It does fit perfectly because of the 3 sections. He’s narrow on the chest so other harnesses just don’t fit him. They are very well made and Jasper is completely comfortable. The staff at this Company really understand dogs and are very keen to help you get the best solution. The before and after service are excellent. I won’t be buying any other brand.
We love that you and Jasper are with us for the long haul, Sue!
Thank you for taking the time to leave us a review and for sharing the pictures of the beautiful Jasper in his harness with us ☺️
Ordered a 3 piece harness when Bonnie was younger and hoped that she would grow into it. She is a small working Cocker Spaniel and hasn’t grown much bigger. We have now bought 2 extra small pieces and the harness now fits much better and she seems happier wearing it.
Mira has been wearing this harness for many years. It's the only one she hasn't been able to escape from and she's a husky that like to pull so this keeps her in check.
I had to get a replacement piece as I left it on the front door one morning and the foxes took it.
Those pesky foxes! Thank you for coming back to us once again, Fred and for sharing the pictures of Mira in her harness with us. Just beautiful ☺️
We have used perfect fit forany years and find them absolutley perfect for our dogs.
Aw, what a lovely picture of your beautiful pair, Mags! Thank you for the lovely review and for being such a loyal customer 😊
A Perfect Fit of course.
Very helpful advice given online Pre-purchase from a real person (not a chatbot)
Dog is very comfortable in the harness.
Great for my border terrier who don’t like over head harnesses So this is perfect
The usual impeccable service.
We love this, Nick! Thank you so much! 😊
Very happy with the harness. After spending lots of money on various off the shelf harnesses which my dog can reverse out of, finally found one that fits and works perfectly.
Well, we are very pleased that you have now found us, Jim ☺️
We love that your pup is safe and secure in their harness.
Superb customer service as always - helped me choose the right size for my growing puppy. Prompt delivery and a great product. I can't recommend PerfectFit highly enough to every dog owner
Thank you for recommending us, Dani ☺️
It is so nice to hear that the team looked after you well and that your order arrived in good time.
Obsessed!!!
And we are obsessed with your beautiful pup in the leopard print! ☺️
Amazing gentle harness
Aw, just look at your little one in their new harness, Julie. Thank you for sharing the pictures with s and for the 5 stars! ☺️
Service superb as ever- very quick delivery- well packaged would recommend to anyone
It is great to hear that the team looked after you so well, Kierstin. Thank you for the lovely feedback ☺️
I love these harnesses for my mini Dachshunds. They are the only ones I've tried that do actually fit properly. Being able to choose different sizes in the individual pieces is great and allows you to customise the fit to suit your dog. They are extremely well made too, I've had mine some time and they show no signs of wear unlike some more expensive ones I previously bought. Washable and quick drying too is a bonus as they get very muddy when out in the fields.
We are so pleased that we are able to help your Dachshunds, Margaret. Happy walkies to you all! :)
Loving Oakley’s new Avocado top piece, we also have Blue, Red and Orange so I think it’s clear we love PerfectFit harnesses. Customer service is brilliant and as we found out lately they really do care about their customers.
Oakley is looking just fab in the Avocado Heidi, love it! Thank you for being such a loyal customer :)
I am really pleased with this harness, I have a long haired rough collie Bonnie and I feel this one is more comfortable for her than the firmer types. Love the fact that you can buy the pieces individually so you can get your best fit. I went to my local pet shop so Bonnie could be fitted properly and different sizes tried on to be sure. I bought the last top piece simply to get the colour I wanted and I knew exactly what size I needed so that made it easier.
It is great to hear that Bonnie is so happy in her new harness, Nicola! Thank you for the review and for sharing the picture of the beautiful Bonnie with us. We are loving the jade on her!☺️
Absolutely brilliant would recommend these harnesses to everyone, the staff are so helpful with everything, any part that is outgrown or worn(highly unlikely)you just have to replace the part.
My dog loves wearing her harness and cries when you take it off.
Aw, this is a beautiful picture, Kim. Thank you for sharing your lovely girl with us and for taking the time to leave us a review! ☺️
The 20mm medium front piece fits atlas perfectly!!
Customer service was fantastic when atlas ate the 20mm small front piece that originally came with his harness.
Thank you for the review, Tori and for sharing the picture of Atlas in his (uneaten) harness with us. Just adorable! ☺️
I had the wine in small but we have now sized up so needed it in medium in my life and I love it
Thank you for the lovely review Tanya and for sharing the picture of the beautiful Herbie with us
These harness pieces are excellent and well made and the company service is excellent and well informed
Thank you for sharing the picture of your beautiful pup in their new harness with us, Kierstin 😊
It is great to hear that you are happy with the quality and that the team looked after you so well.
Excellent harness it looks so comfortable on and my dog likes wearing it
We love that your dog seems happy and comfortable in their harness, Jayne!
They are certainly looking very smart in it! 😊
