Fireworks night, a house move, a long drive to the vet: the moments a dog needs help settling tend to arrive in clusters, and a calming collar that has been sitting in a drawer since last November is usually past its best by the time you reach for it. Buying four at once means there is a fresh one to hand each time rather than one you opened and half forgot about.

Each collar is adjustable, so a single size covers a wide range of dogs, and the material is waterproof. That is worth having, because a calming collar that has to come off for every wet walk stops working the moment you forget to put it back on. The manufacturer quotes up to 60 days of wear from each collar, and that clock starts when the pouch is opened rather than when you first buckle it on.

• Pack of four collars

• Natural ingredients intended to help dogs settle
• Package measures 15 x 10 x 3cm and weighs 80g

Honest about what these do. Pheromone collars take the edge off mild stress for some dogs and do nothing at all for others, and no collar will carry a genuinely phobic dog through a firework display on its own. Use one alongside a quiet room, background noise and a plan agreed with your vet. Note also that this range includes cat versions as well as dog, so check the option selected at checkout.

Who it's for: Owners of a mildly anxious dog who want a supply ready for fireworks season, travel and vet trips rather than one collar bought in a panic.
