Rëndslong

A high-reward treat that’s clean, lean, and actually delicious.

Beef lung has earned its place as a favourite among raw feeders — and it’s easy to see why. It’s incredibly light, gently airy, and naturally crisp once freeze-dried, which makes it irresistible for dogs and perfect for training. Despite its fluffy texture, it’s packed with high-quality protein and remains naturally low in fat, giving you an organ-based reward that feels indulgent for your dog but guilt-free for you.

Because it’s so easy to chew and digest, even sensitive dogs tend to do well with it. It’s the kind of treat that keeps tails wagging without adding unnecessary calories — a simple, honest ingredient that delivers both flavour and function.

Because lung is low-fat and not as nutrient-dense as liver or kidney, it’s generally safer as a more frequent treat. Many people use it for training because it’s light, crunchy, and doesn’t overload the diet.

Useful rule of thumb:

Treats (including lung) should stay under 10% of your dog’s daily calories.

Beef lung fits beautifully into this because it’s lean, satisfying, and doesn’t spike calories the way fattier treats do.
