Sizing
Measure once.
One measurement, the chest, and the chart does the rest.
Step one
Stand your dog up. Wrap a soft tape around the widest part of the chest, just behind the front legs.
Small
40 to 55 cm. Whippets, staffies, kelpie pups, most cavoodles.
Medium
55 to 70 cm. Kelpies, border collies, labradors on the lean side.
Large
70 to 95 cm. Shepherds, retrievers, big labradors, ridgebacks.
Between sizes
Go up. The straps adjust down further than they adjust up.
Wrong anyway?
Thirty days. We send the right one first and you post the other back, on us.
Measured?
Order the kit in that size. If we got it wrong, we swap it.
