Dog Collar Sizing

It can be confusing deciding what collar size your dog needs, not helped by the fact that every manufacturer measures collars differently. You can guestimate the collar size, however, if you want to get the really right fit than there’s no way round it – its dog measuring time!

So, arm yourself with some dog treats and a soft tape measure (or piece of string and a ruler if no measure available) and off you go.

  1. Try and get your dog to stand still.
  2. Measure the length around your dog’s neck – at the baseline – which will be where the collar usually sits.
  3. Do not throttle the dog or equally hang the tape measure so loosely that it hangs down. Make a measure that is a sensible fit – secure but with a cm or two for flex.
  4. Refer to our size guide below.
