Barc London Size Guides

Getting the right fit is everything. Use the guides below to find the perfect size for your dog and measure up before you order, even if you've shopped with us before.

All guides for items now in our 'Special Prices' collection can be found further down the page.

How to measure your dog

For collars:

Wrap a soft tape measure around the base of your dog's neck, where the collar would naturally sit.
Keep the tape snug but comfortable – you should be able to slide two fingers underneath.
Note the measurement in centimetres and match it to the size guide below.

For harnesses:

Wrap a soft tape measure around the widest part of your dog's chest, just behind the front legs.
Keep the tape flat against the coat – not too tight, not too loose.
Note the measurement in centimetres and match it to the size guide below.

For coats and jackets:

Chest: Wrap the tape around the widest part of your dog's torso, just behind the front legs.
Back: Run the tape along your dog's topline from the lower neck to the base of the tail. We recommend the jacket back length be slightly shorter than this measurement.
Neck: Measure at the widest point, leaving room for two fingers to fit comfortably underneath.

For leads: Use your dog's collar or harness size as a guide. As a general rule, smaller and lighter dogs tend to suit the S lead, while larger or stronger dogs are better suited to the L.

If your dog is between sizes, we recommend sizing up. Not sure? We're always happy to help, just get in touch.
