Find their size 📏
The Shark Vest runs 1–2 sizes small (Asian sizing). Two minutes with a soft tape measure now saves a re-order later.
How to measure
- Back length — base of the collar to the base of the tail, standing straight.
- Chest girth — around the widest part of the ribcage, just behind the front legs. Snug, not tight.
- Weight — use it as a tie-breaker, not the main measurement. Chest wins every time.
🐾 Wiggly dog? Measure while they're eating — works every time.

Manual measurements — allow ±1". Breed examples are typical adults; your dog's tape measure outranks their breed.
⚠️ The honest sizing rules
- Between sizes? Always size up. A slightly roomy vest floats fine; a tight one stays in the closet.
- Chest girth beats weight. A stocky 20 lb Frenchie and a lean 20 lb Whippet wear different sizes.
- Short-snouted breeds (Frenchies, Pugs, Bulldogs) — size up if the chest is near the top of a range; they carry it broad.
- Wrong size anyway? 30-day returns, no restocking fee. We'd rather swap it than have it not fit.
