Perfect Fit Harness

Perfect Fit Harness


The Perfect Fit Harness is an evolutionary harness which comes in 2-3 separate pieces in 4 different size ranges (Tiny, 15mm, 20mm and 40mm) and 13 different colour options. Within each size range there are between 5 and 11 different sized pieces, enabling us to get a snug custom fit for almost any size/shape of dog (cats, rabbits, pigs too!)

They are great for uniquely shaped dogs light sight hounds, Dachshunds, Basset Hounds, Bull Dogs, tiny breeds and giant breeds. *Please note - you cannot interchange pieces from different size ranges*.

With up to 5 points of adjustment we can alter the harness accordingly to each dog, ideal for growing puppies as the harness can grow with the puppy with the option of buying individual pieces when necessary.

It has a D-ring which sits on the dogs back and a D-ring which sits on the front of the dogs' chest, which means you can use the 2 points of contact with a double ended lead for more control over strong dogs. The D-rings are made of stainless steel to prevent rusting, and the harness is fully machine washable, do not tumble dry.

The Perfect Fit was designed not to go on over the head, we clip the harness around the dog rather than having to manoeuvre the dog into the harness, much less invasive. Furthermore, if a harness goes on over the dogs head then there's a chance they could back out of it.

The Perfect Fit Harness sits on the skeleton, avoiding pressure points, soft tissues and the throat/neck area, giving the dog full range of movement to run, swim and jump. Covered in thick padded fleece, the Perfect Fit offers the utmost comfort for the dog and also helps the harness to adhere to the dog's coat, preventing chaffing and slipping. Due to its comfort, we have found that it often has a calming/rebalancing effect on dogs. This is a more complex harness to fit than most, but by far the pioneer of harness design.

The Fitting Process

Once you have picked your appropriate size range and 3 pieces, with the help of the breed chart, you can now try it on your dog.

Before putting the Perfect Fit Harness on your dog, it should be connected by 1 clip at the front only. Put the top piece on the dogs back and clip the Y shaped front piece around the throat area like you are putting on a collar. The rest of the harness goes between the dogs front legs and then clips up either side of the chest behind the front legs.

If you're struggling to clip the harness around the dog, then make appropriate adjustments to the harness, equally both sides. Remember, there are up to 5 areas of adjustment: 2 either side of the shoulders, 2 either side of the chest and 1 at the bottom of the front Y shaped piece, which sits between the dogs front legs. You should be able to get 2 flat fingers under the harness on all areas. Any more or less than this then you should consider swapping the relevant piece for a better fitting one. For example, if you find that the front piece is too baggy, then you can try a smaller one. If the front piece is the smallest one we do in this range then you can, alternatively, downsize the top piece instead, this will bring the front piece in more snuggly.

The front piece should not come into contact with the soft tissues of the neck area. The girth straps should be sitting behind the front legs coming up as vertically as possible, the adjustment at the bottom of the front piece helps to move this girth piece back if it is too close to the armpits. Furthermore, any puckering in the top piece suggests that this piece is a little too big.


We always aim to fit puppies into the bigger of the 2 ranges if they happen to sit on the cusp, the same applies for adult dogs too. The wider harness provides more padding and evenly distributes the weight better for pulling dogs. This, however, does not mean that we should compromise the fit of the harness just because the dog is growing, instead we need to be more mindful of the customer and how much they are willing to spend on their dog. Despite the fact that comfort and safety is even more paramount for growing dogs, some customers would rather hold off buying a harness if their dog is 2 inches away from fitting into the bigger range for example.

Generally, from the age of 20 weeks the top piece tends to stay the same, but the front and girth will need replacing over the coming months. This is only a guide as every dog is an individual, for example a 20 week old Dogue De Bordeaux will likely need all 3 pieces replacing before the age of 1 year, and if he was presented to us at 8 weeks old, then he is likely going to outgrow 3 harnesses!

Front D-ring

The front D-ring is only to be used in conjunction with the back D-ring by using a double-ended lead or 2 leads. Here's why - if the lead is only attached to the front D-ring then it is always going to be pulling either to the left or right side of the dog, which will be very unbalancing for him. For the reason, the front D-ring is NOT designed to take the pressure that the back D-ring can. If you connect one end of the lead to the back D-ring where the majority of the dogs  weight will be taken, you can then use the front connection as a steering aid or brake as and when needed.

Escapologists & Tripaws

These harnesses can be very difficult for Houdini dogs to escape from! This is because we can make the neck hole smaller than the skull by clipping the harness around the neck rather than going on over the head. Harnesses which go on over the head can be easily backed out from. Using a double ended lead can also help to prevent the dog escaping. *Please note - it is never impossible for the dog to escape* A link can be used from the D-ring to the collar if necessary.

Due to the modular design, we are able to snugly fit front leg amputees - whether they have a small stump remaining or not.
