Almost no pet hat tells you the one number you actually need, which is why this one is worth a look: the strap adjusts across a neck of 24 to 27cm, and nothing else. Measure under the chin where a collar sits before you order, because outside that band there is no more adjustment to be had and no second size to fall back on.

The antlers hold their shape because they are filled with PP cotton rather than left as flat fabric, so they stand up in a photograph instead of flopping sideways within a minute. The outer is polyurethane with a slight sheen, wiped clean rather than washed, and the strap closes on Velcro - quick to fit, and quicker still to pull off when the dog decides it has had enough.

• One size, Velcro-adjustable across a 24-27cm neck
• Polyurethane outer with a soft sheen
• PP cotton filling in the antlers so they stand upright
• Brown, single colourway
• Weighs 23g
• Recommended for small dogs and cats

On sizing: one size and one narrow neck range means this genuinely does not fit most medium and large dogs, and we would rather say so than take the order twice. Measure first. As with any headwear it is for short supervised spells and photographs, never left on an unattended pet, and off immediately if they start pawing at it.

Who it's for: owners of Chihuahuas, Pugs, Yorkshire Terriers and cats who want antlers that stay put for the length of a Christmas photograph.
