Best Jackets for Big Dogs: Sizing, Warmth and Everyday Styles

Choosing jackets for big dogs starts with fit, movement and the weather your dog will actually face. A jacket can look right in a photo but still feel uncomfortable if it pulls across the chest, restricts the shoulders or finishes too far up the back.

How should a big dog jacket fit?

Measure from the base of the neck to the base of the tail while your dog is standing naturally. Then check the chest at its widest point. The jacket should sit close enough to stay in place, with enough room for your dog to walk, sit and turn comfortably.

• Check shoulder movement: the front legs should move freely without fabric pulling behind them.
• Allow chest room: broad chested and fluffy dogs may need the roomier option.
• Watch the back length: a jacket that is too short gives less coverage, while one that is too long can shift or bunch.
• Measure each product: do not rely on breed name alone, because dogs of the same breed can have very different proportions.

Use the Lucky Pup dog clothes size guide before ordering. Lucky Pup jackets currently run up to 2XL with a 50cm back length, so check the chart carefully if your dog is near the top of the range.

Choose the jacket for the walk

Puffer jackets for colder days

The Dog Puffer Jacket is the warmer choice for chilly mornings and colder everyday walks. Check chest room carefully if your dog has a powerful build or thick coat.

Parka jackets for changeable weather

The Dog Parka Jacket is a practical outer layer for cooler, changeable routes. It is the place to start when coverage matters more than a dressed up look.

Denim dog coats for dry walks

A denim dog coat is a lighter style layer for dry town walks, pub garden stops, birthdays and photos. If you searched for a denim coat dog style, this is the casual option rather than a rain or winter coat.

Varsity jackets for weekend style

The Dog Varsity Jacket is another dry day option for weekend outings, birthdays and photos. Choose it for style, then use the same back length and chest checks before buying.

What if your dog needs more than 50cm back length?

Do not squeeze a larger dog into a jacket simply because 2XL is the biggest label. If your dog needs more than a 50cm back length, compare the Dog Football T shirt, which offers the longest size route in the current Lucky Pup range, or wait for a jacket whose measurements genuinely suit your dog.
