The harness with
the PerfectFit

The unique ethical dog harness that will make your dog happier and your life easier.

Traditional Leads & Collars


The area around a dog’s throat is one of the most vulnerable yet is often an overlooked part of a dog’s anatomy. Pressure from a collar and lead can restrict blood flow and neural pathways and cause or exacerbate many physical conditions including:

  • Eye problems caused by Intraocular eye pressure
  • Collapsed Trachea
  • Syringomyelia
  • Brachycephalic obstructive airway syndrome
  • Sensitive throats (e.g. after Kennel cough)
  • Thyroid disorder

A collar or lead can also inhibit recovery following surgery.

Pain or discomfort in any form increases arousal levels and can have a direct impact on your dog’s emotional state and therefore, their behaviour.

PerfectFit Harness


Our modular design of interchangeable pieces means we can cater for all shapes, ages and sizes of dogs ensuring a snug, safe and comfortable fit.

Made with your dog’s health, comfort and safety in mind, the PerfectFit Harness has been designed with a ‘Y’ shaped front meaning pulling force is evenly distributed through the chest rather than the soft tissues of the neck and throat. With no straps cutting across the front legs, your dog will have full freedom of movement to enjoy the walk.

What Clients Say

The perfect fit, and the fact that it comes completely adjustable, in three parts, meant that I could finally find a harness that fitted them perfectly in every aspect. Without rubbing them raw in some places and without making them uncomfortable. The fleece lined parts are the ONLY harness that doesn’t rub my boy's fur right off! Love it. Love everything about it!

Dash has been wearing perfect fit for 2 years now, she is a very nervous dog when walking in the streets and she is noticeably more confident since wearing the Perfect Fit.

You really do get what you pay for! This is hands down the best harness we’ve ever had and we’ve tried most of them out there. The added bonus that it is fully machine washable which is perfect for water loving mud monsters like Willow.

Perfect Fit was recommended by our breeder and we've passed on that recommendation many, many times. The harness really is a 'perfect fit' that doesn't restrict movement in any way, it hasn't caused any matting of our girl's super curly coat and it's very cost effective to be able to replace individual parts. When I've called for sizing advice customer service was amazing. We wouldn't change to anything else.

Since switching to Perfect Fit 5 years ago he's had no more skin problems, and he immediately started walking better. We've since switched our other dogs to Perfect fit, they are durable and comfortable for the dogs, well worth the money. Perfect fit by name, Perfect in every other way ... The best thing about perfect fit harnesses, they don't rub, no red mark's anywhere!! The design also gives me great comfort that Roo's joints aren't restricted in anyway, it allows her perfect shoulder movement & the feeling of freedom, they wash well, dry fast ... & great Value for money, fast delivery & great customer support.

The difference in Rigby’s demeanour when putting the Perfect Fit harness on is huge, there’s no shying away, he’s actually excited to put it on! It’s also had a positive impact on his stress levels while out walking because he’s now not stressed before leaving the house. The harness coupled with his reactive training has made such an improvement to his quality of life and it’s only been a matter of weeks. I honestly wish I’d found this harness sooner.
