Cairn Terrier feeding guide: how much and how often

Daily calories, portions by age and practical feeding tips for the Cairn Terrier.

A 7 kg (15 lb) Cairn typically needs 90 to 120 g of dry food a day, about 1 to 1.3 cups, split into two meals. That amount is small, which means treats can quickly tip the balance: three small biscuits can add ten percent to the daily intake. Cairns are persuasive beggars and gain weight easily after neutering, so weigh your dog monthly on a kitchen scale by weighing yourself holding it.

A shallow to medium-depth stainless steel or ceramic bowl suits the breed's short muzzle and is easy to clean. Some Cairns develop itchy skin or ears, and diet is occasionally a factor; if your dog scratches, chews its feet or has recurring ear trouble, ask your vet before switching foods repeatedly.

Puppy portions need measured weight, growth stage and the food’s energy content. A breed-average curve is not a feeding plan. Calculate with measured inputs and review the result with your vet.
