A dull coat is one of the more visible signs that something in a dog's diet isn't quite covering everything it needs, which is the gap a mineral-rich seaweed supplement is aimed at filling.

This is Ascophyllum nodosum seaweed meal, analysed at 19.47% crude ash, 8% crude fibre, 4% sodium, 1.2% calcium, 0.8% magnesium and 760mg/kg iodine — all naturally occurring in the seaweed rather than added separately. AniForte's guidance is 0.5g daily for every 10kg of the dog's body weight, using a quarter scoop, mixed into food, and they note individual needs can vary depending on diet and overall constitution.

One thing worth knowing. AniForte specifically say to consult a vet before use if your dog has thyroid disease, because of the naturally high iodine content in seaweed — this is the one product on our shelf where that particular caution is on the label itself, not just general advice.

Who it's for: owners of dogs without a known thyroid condition who want a natural mineral top-up, particularly for coat condition, mixed into daily food.
