Liver is one of the most powerful natural training rewards available — the smell alone is enough to cut through distraction in even the most challenging environments. At 70% protein and just 2.2% fat, these chunks deliver maximum reward value with minimal calorie load, making them ideal for frequent use in training sessions without disrupting your dog's diet. The firm dried texture means they break cleanly into smaller pieces, giving you full control over reward size. Single ingredient, British provenance, recyclable packaging — this is exactly what a ProTrain treat should be.

Are these suitable for dogs with allergies?

Yes — single ingredient (100% beef liver), no additives, no preservatives, no grain. Suitable for most dogs with food sensitivities. If your dog has a known beef allergy, choose an alternative protein treat.

Can I break them into smaller pieces?

Yes — the firm dried texture breaks cleanly, giving you full control over reward size. For training, we recommend breaking into pea-sized pieces for small dogs and thumbnail-sized pieces for larger breeds.

How much should I give per day?

Treats should not exceed 10% of your dog's daily calorie intake. Adjust main meal portions on heavy training days. These are low fat (2.2%) so they're forgiving, but moderation is still important.

Which size should I buy?

The 250g is ideal for trialling or occasional use. The 600g offers better value and is the practical choice for regular trainers or multi-dog households.

ProTrain Academy Tip: Liver is a high-value reward — use it strategically. Reserve liver chunks for the most challenging training moments: first off-lead recall in a new environment, introduction to gunshot, or breaking a persistent bad habit. Using high-value rewards for routine tasks reduces their power over time. Keep liver for the moments that matter most.

Intensely savoury, rich liver aroma — one of the most powerful natural scents for dogs. The dried texture concentrates the flavour, making these chunks significantly more aromatic than fresh liver. Deep, meaty, and irresistible — even the most distracted dog will notice these in your pocket.

One ingredient. Maximum reward. Train smarter, not harder.
