Dog Product Size & Care Guide

Size & care guide

Measure once. Choose with confidence.

Dog clothing fits best when you start with back length, then check chest room for comfort and movement. Use this guide before choosing a Lucky Pup tee, hoodie or jacket.

How to measure

Back length: measure from the base of the collar to the base of the tail while your dog is standing.
Chest: measure around the widest part of the rib cage.
Comfort room: allow space for walking, sitting and curling up.
Shape check: broad chested, long backed or very fluffy dogs may need extra room.

If your dog is between sizes

Choose the size that gives the most comfortable chest room without swamping the back length. For thicker layers such as hoodies, puffers and parkas, a little extra room is better than a tight fit.

If you are unsure, email the back length, chest measurement, breed/build and the style you are considering.

Quick route for bigger dogs: If your dog measures 55cm or 60cm along the back, start with the dog football T shirt, then read the large dog clothes fit guide before comparing the wider dog clothing collection. For 45cm or 50cm dogs, compare tees, hoodies and jackets by chest room as well as back length.

Choosing a coat for wet walks? Start with back length and chest room, then read the dog coat size guide for wet UK walks and the big dog coats fit checks before comparing the puffer jacket, parka jacket, denim jacket and varsity jacket.

Style fit notes

Raglan tee: light everyday layer. Keep the fit comfortable rather than tight.
Football tee: sporty, lightweight layer with the widest size availability.
Hoodie: allow a touch more room for movement and warmth. For extra fit help, read the dog hoodie size guide or the big dog sweaters guide.
Denim jacket or varsity jacket: check chest room before choosing the neatest back length.
Puffer or parka: warm outerwear. Avoid sizing down.

Care basics

Always check the care label on the garment first. As a simple rule, wash gently, avoid harsh heat, fasten closures where relevant, and let jackets dry fully before storing.

Keep clothing clean and dry between walks so it stays comfortable for your dog.

Find a fit route by dog shape

Different breeds can need different checks even when the back length looks similar. Use these fit guides before choosing a Lucky Pup layer, then come back to the main size table before checkout.

Broad chested dogs: read the French Bulldog fit guide, Pug fit guide or Staffie fit guide.
Curly coated dogs: compare the Cockapoo fit guide, Maltipoo fit guide and Cavapoo fit guide.
Larger dogs: start with the large dog clothes guide, then compare the big dog coats guide and big dog sweaters guide.
