What size?

Here at Fat Paws HQ we're used to having dogs the size of small carthorses and have stopped thinking of them as large hounds. That doesn't mean though that your smaller (but perfectly formed) pooches should miss out and we're trying to cater for all sizes from tiny to huge.


If you need a tiny puppy collar making or one for your outsized canine companion: please ask and we'll do our best.

Fitting and measurements for Fat Paws collars:

Fitting a martingale:


A properly fitted martingale should be comfortably loose when the dog is stationary. When the martingale is pulled the two slides (D rings or tri glide buckles) should pull close together, but should never touch.



Ziggy (left) is modelling a 1.5 inch (38mm) reduced loop martingale to demonstrate.

Update: fitting a martingale can be tricky as it's very easy to get wrong.Believe us, we've done it incorrectly ourselves and we make them!


What we have done is make 2 videos, with Deborah from D.O.B,  and posted them to YouTube.


Apologies: there was only meant to be one clip, but we had to stop filming and fall about laughing when Big Sam came blundering in the room to give me dirty looks for talking so loudly - sorry!

Tag Collars are very simple, but rather than throw numbers at you they have their sizes and measurements detailed on the listings only.


Note: one measurement you do have to bear in mind with regards to all of our collars is the widest part of your dog's head as they all slip over the head and are adjusted to size.

Where and what to measure:


We hope the diagram below is fairly self-explantory and if you don't have a soft tape measure handy you can always use a piece of string/ ribbon and measure that with a ruler after fitting it around each of the three points.
