Big dogs are not automatically warm dogs. A greyhound, a boxer or an ageing labrador can be shivering on a walk while a small terrier trots along perfectly content, and most winter coats stop at a size that assumes otherwise. This one starts at XL and runs all the way to 6XL, which is the first reason to look at it: it is cut for the dogs the rest of the market quietly forgets about.

The construction is a waterproof polyester outer over thick PP cotton wadding, with a soft lining against the dog. The outer turns wind and light rain while the wadding is what actually holds the heat in. A D-ring on the back takes a lead directly, so you are not threading a clip under a coat to reach a harness in the rain. It pulls on over the back and fastens quickly, and a separate liner is offered for milder days.

• Waterproof polyester outer with thick PP cotton filling
• Soft lining against the coat
• D-ring on the back for lead attachment
• Sizes XL, 2XL, 3XL, 4XL, 5XL and 6XL
• Separate liner available as an option
• Weighs between 400g and 730g depending on size

Two things worth knowing. Despite the polar fleece name, the specification lists a waterproof polyester shell with PP cotton wadding, so this is a padded winter coat rather than a plain fleece jumper: warmer, but bulkier than the name suggests. And there is nothing below XL here, so small and medium dogs are not catered for.

Who it's for: Large and giant breeds, and thin-coated or older dogs who feel autumn and winter properly.
