What size winter vest should I order for my dog?

This vest runs small — a 21 lb dog fits a 2XL. Measure the chest at the widest part of the rib cage, pick the size whose chest number clears your dog's measurement, and when in doubt, go bigger. If the weight lands at the top of a range, go up one size; deep-chested dogs add one more.

How do I measure my dog for a vest?

Chest girth: wrap a soft tape around the widest part of the rib cage, just behind the front legs. Back length: base of the neck to the base of the tail, standing square. Neck: where the collar normally sits. Chest is the measurement that matters most for a back-zip vest.

What size dog booties should I order?

Booties size on paw width, not weight. Measure the widest part of a front paw with the dog standing on it. They run small — between sizes, go up; the drawstring cinches a slightly roomy boot snug, while a tight one compresses the paw and gets kicked off.

Chest is the measurement that matters most for a back-zip vest.

How to measure

Chest girth: wrap a soft tape around the widest part of the rib cage, just behind the front legs.
Back length: base of the neck to the base of the tail, standing square.
Neck: where the collar normally sits.

How to choose

Pick the size whose chest number clears your dog's measurement.
If the weight lands at the top of a range, go up one size.
Deep-chested dog? Add one more. A roomy vest layers over a sweater; a tight one restricts the shoulders.
Buyer reference points: a 21 lb dog fits a 2XL; a 4XL on a larger dog was "a bit loose in the back but otherwise perfect."

Booties sizing — paw width, not weight

Booties size on paw width, which weight can't predict. Measure the widest part of a front paw with the dog standing on it (paws spread under load).

Seven sizes, XXS–XXL, for small and medium dogs and cats. They run small — "too small" is the most common sizing complaint on the source listing, and "correct size" reviews cluster where buyers sized up. Between sizes, go up — the drawstring cinches a slightly roomy boot snug, while a tight one compresses the paw and gets kicked off.
