Thirty styles is an unusual amount of choice for a novelty item, and it is the reason this one turns up in so many photographs. There is a curly wig in the list for most jokes you might be trying to make. The wig is held on by a strap that fastens under the chin, which keeps it in place rather better than a wig that simply rests on the head.

That chin strap is worth thinking about properly. It works because it is under tension, and anything under tension around an animal's head and jaw needs a person watching it. Fasten it loosely enough to slide a finger underneath, check your pet can open her mouth and pant normally, and take it off the moment the photograph is done. Comic effect is the whole purpose here; comfort for a whole evening is not on offer.

• Comic curly wig with a strap that fastens under the chin
• Thirty styles listed
• Suitable for cats and dogs
• Made for photographs rather than extended wear
• Quick to fit and quick to remove

A chin strap raises the stakes. Never leave this on an unattended pet, never overnight, and never during play with another animal, where a strap can be caught by teeth or a claw. Panting is how a dog cools herself, so anything crossing the jaw comes off before a walk or a warm room. Styles are listed by number rather than description, so tell us the look you are after and we will match it.

Who it's for: Owners after a genuinely funny photograph, with a tolerant pet, a short session and somebody else holding the camera.
