Brit Functional Snack Endurance, 150 g is a functional semi-moist dog treat with lamb and banana. It's designed for active dogs and enriched with L-carnitine and taurine to help keep them in good shape. It contains no grain or potato, and fulvic acids, according to the manufacturer, improve nutrient absorption. Cantaloupe melon extract is added as a source of antioxidants. It's part of the Brit Functional Snack series, where each treat has its own purpose.
Why L-carnitine and taurine
L-carnitine helps carry fatty acids into cells, where they're turned into energy — which is why it's often added to diets for active and sporting dogs. Taurine supports the heart muscle. Brit Endurance contains 1,000 mg of L-carnitine and 1,500 mg of taurine per kilogram. Banana adds potassium, magnesium, vitamins C and B6 and fibre, while lamb provides essential amino acids. For an active dog's main diet, see our review of Brit Premium Sport.

How to give it
The manufacturer suggests giving the treat daily — as a training reward or simply during the day. There's no exact amount, so follow the general rule: treats should be no more than 10% of daily calories, and cut back the main food if there were a lot of treats. For training, break the pieces smaller — more in treats for dog training. Your dog should always have plenty of fresh water, especially after exercise.
An active dog: what else matters
A treat is just a nice extra. An active dog needs a quality main food, a sensible exercise routine and rest. In hot weather, move training to the morning and evening — tips in dogs in hot weather: how to prevent overheating.
