Short-coated dogs lose heat from the head and ears faster than most owners expect, and on a raw January morning that is the difference between a walk they enjoy and one they endure. A knitted hat is a small fix for it. This one is worked in a windproof knit with a row of soft spines running along the crown, so it does something as well as looking like something.

It pulls on over the head and sits behind the ears, and the knit has enough give to stay put without gripping. There is no hard structure anywhere in it, so nothing digs in when your dog shakes. The same style comes as a fox, a white rabbit, a black cow and a Master Yoda version, in small, medium and large, which is worth knowing if the dinosaur is not the one that suits your dog's face.

• Windproof knitted construction for cold-weather walks
• Dinosaur spines along the crown
• Also made as fox, white rabbit, black cow and Master Yoda
• Sizes S, M and L
• Soft, unstructured knit with no rigid parts
• Pulls on over the head and sits behind the ears

Two things worth knowing. A hat is a costume piece rather than kit: put it on for a supervised walk or a photograph and take it off afterwards, never leaving it on an unattended or sleeping dog. And measure the head and neck, not the chest. The generic size guide attached to this style quotes a chest measurement, which tells you nothing about whether a hat will fit.

Who it's for: Short-coated small and medium dogs who feel the cold, and owners who do not mind a bit of daftness on the winter walk.
