Your dog’s girth measurement, breed, and age should be all you need to correctly size your dog.
For sizing advice for the Perfect Fit Harness a good place to start is the perfect fit’s searchable Breed Chart.






Designed with the escapologist in mind.

If a harness is placed over a dog’s head, then the ‘head hole’ must be bigger than the dog’s skull and so the dog could back out of the harness.
When using the Perfect Fit, the top and front pieces are clipped around the dog’s neck. A correct fitting (being able to insert a couple of fingers between the webbing and the dog’s body) ensures that these cannot be drawn over the dog’s skull. This was how the Perfect Fit was designed to be used.

It is fleece lined to protect a dog’s skin from plastic clips; also the width of the fleece helps to spread pressure over a larger area rather than just the width of webbing as with many other designs

Fully machine washable, but don’t tumble dry

Changed to stainless steel rings to prevent rusting particularly from seawater

Break a clip and only replace one piece of the harness and not the whole harness

As the dog grows, there are 5 areas of adjustment to accommodate this growth. As these adjusters reach the end of their extension, new individual larger pieces can be purchased

For top pieces, there is a range of coloured fleece and coloured webbing (see website); the front and girth pieces are only available in black

UK design and manufacture with all labour and materials sourced from within the UK and sold only by independent outlets trained on fitting harnesses to dogs

The 15mm range now includes Bases (sizes 8,10,12), thus making this range either a 2 piece (similar to the 10mm range) or a 3 piece harness. The inclusion of Bases into the 15mm range is to remove the need for the clip and ring to attach the front and girth pieces like these can make lying down uncomfortable for the dog.
