Comfort-led dog anxiety support inspired by the original Rein Coat brand.Questions? Contact us

Measure twice, comfort once.

A good fit should feel secure while still allowing the dog to stand, sit, lie down, and move naturally.

How to measure

Use a soft tape and keep the dog relaxed.

  • Chest girth: measure around the widest part behind the front legs.
  • Back length: measure from lower neck to the base of the tail.
  • Lower neck: measure where the front of the coat will rest.
  • Behavior check: remove the coat if your dog resists, pants heavily, freezes, or tries to chew it off.
