FIND THE RIGHT FIT
Mountain Valley Pet Costumes Size Guide
A comfortable fit starts with three simple measurements. Use a soft tape, keep it level and measure while your pet is standing naturally.
How to measure
1 · Neck
Measure around the base of the neck where a collar naturally sits. Allow room for two fingers.
2 · Chest
Measure the widest part of the ribcage, usually just behind the front legs. Keep the tape snug, not tight.
3 · Back
Measure from the base of the neck to the base of the tail along the spine. Do not include the tail.
Between sizes?
Choose the larger size for comfort, especially for broad-chested pets or garments designed for layering. Product-specific notes should always take priority.
