Nobody names a supplement this bluntly unless it is aimed at a dog who has started taking the stairs one at a time. Stiffness after a long walk, a slower start on cold mornings, a reluctance to jump into the boot: those are the changes owners tend to notice first, and they are the usual reason somebody reaches for a daily supplement. These are chicken-flavoured tablets from Pets Calm Down, made here in the UK.

Ninety tablets come in a 200 gram tub and are taken as a treat rather than pushed into food, which is the practical difference between a supplement that gets given every day and one that ends up at the back of a cupboard. Supplements of this kind are a long game as well. They support everyday wellbeing over weeks rather than doing anything you would notice by Thursday, so it is worth committing to a full tub before you judge it.

• 90 tablets per tub
• Chicken flavour, given as a treat
• 200g net weight
• Made in the UK by Pets Calm Down
• Natural supplement intended for daily use

Be realistic about this one. Introduce it gradually, follow the pack guidance, and see your vet first if your dog is limping, unwell or already on medication, because stiffness that came on quickly needs examining rather than supplementing.

Who it's for: Older dogs slowing down gradually, and owners who want a daily supplement their dog will actually take without a fight.
