The sound of a dog scratching at three in the morning is one plenty of owners know too well, and by the time the skin is broken it has usually been going on for weeks. These chicken-flavoured tablets come from Pets Calm Down and are made in the UK, intended as everyday support for a dog whose skin and coat need help from the inside rather than something reached for only when the itching flares.

Ninety tablets to a pack, given as a treat, which suits dogs who regard anything on a spoon as suspicious. Anything working on skin and coat works over weeks rather than days, simply because a coat takes that long to turn over, so the honest expectation is that you keep giving them consistently and judge after a month or two rather than after a week. Follow the pack guidance for your dog's size and build up gradually alongside food.

• 90 tablets per pack
• Chicken flavoured, taken as a treat
• Made in the UK by Pets Calm Down
• 200 g pack weight
• Intended as ongoing daily support rather than a one-off dose
• Shipped tracked to the UK with our 14-day returns promise

Worth saying plainly. Persistent scratching almost always has a cause, whether that is fleas, a food ingredient, a pollen allergy or a skin infection, and no supplement will fix any of those. Get the cause looked at by a vet first and treat this as support for a dog whose skin is otherwise being managed. Check with your vet before starting if your dog is on medication.

Who it's for: Owners of itchy dogs who already have the underlying cause in hand and want a simple daily supplement to back up skin and coat condition.
