What matters most for dogs for allergies

For an allergy-prone small dog, the supplement’s carrier and flavourings matter as much as the joint actives. Look for a limited-ingredient chew with a single, novel protein base or a flavour-free powder you can mix into a food your dog already tolerates, so you are not introducing a new allergen alongside the glucosamine and omega-3.

Introduce it alone, not at the same time as other diet changes, so any reaction is easy to trace. Watch skin, ears and stools over the first couple of weeks, keep the dose matched to your small dog’s weight, and if your dog has diagnosed allergies, clear the specific product with your vet before starting.
