The first thing most people notice about a dog's teeth is the smell, and by the time the breath has changed the problem is not the breath. Teeth are the part of a dog that gets worse quietly, on a schedule nobody is watching, in a mouth most of us only look inside when something has already gone wrong.

This is a powder rather than a paste or a chew. Supernature describe it as 100% natural, carrying vitamins, minerals and amino acids, working from the inside out to freshen breath and help reduce tartar build-up, and free from fillers or additives. It has a naturally minty flavour and the instruction is simply to sprinkle it onto the food, so no brushing is involved, which is the whole reason a product in this shape exists.

• 60G tub
• Sprinkled onto food, no brushing required
• Described as 100% natural and free from fillers or additives
• Naturally minty flavour
• Carries vitamins, minerals and amino acids
• A daily routine rather than a one-off treatment

What the label does not say. Supernature publish no ingredient list to us at all. 'Vitamins, minerals and amino acids' names a category, not a composition, and no daily amount reaches us either, so you will be working from whatever is printed on the tub in front of you. Their own copy also says it is approved by vets without naming who, which is worth reading as marketing rather than evidence. And no powder takes off tartar that has already set hard on a tooth: that is a scale and polish under anaesthetic, and a dog with red gums or a tooth gone brown needs your vet rather than a supplement.

Who it's for: owners of a dog who will not tolerate a toothbrush and who would rather do something small every day than nothing at all, and anyone looking for a dental habit that adds nothing to the walk and nothing to the treat jar.
