Measuring for a collar

Neck

Measure around your dogs neck, where their collar would normally sit. Leave a little extra space, 2 fingers should fit comfortably under the tape measure

We recommend sizing up if your dog is at the very edge of a size bracket.

Measuring for a harness

Neck & Chest

Neck
Measure around your dogs neck, where their collar would normally sit. Leave a little extra space, 2 fingers should fit comfortably under the tape measure.

Chest
Measure around the widest part of your dogs chest. Again leave a little wiggle room! You may also want to take jumpers/jackets fitting under the harness into consideration.

We recommend sizing up if your dog is at the very edge of a size bracket.

Both their neck and chest measurements need to fit the same harness size. If they fall into different sizes, recheck the measurements and ask us for help.
