Dr John Titanium

A working or sporting dog doing serious mileage needs both the fuel to keep going and something looking after the joints doing the work, which is why this recipe combines a genuinely high protein figure with a named joint-support extract rather than relying on protein alone.

Dr John Titanium is built from wheat and rice as the cereal base, poultry (14% chicken) as the named protein, poultry oil and linseed as the fat sources, plus yeast, whey, chelated zinc and selenium, dicalcium phosphate, yucca extract and green-lipped mussel with ayurvedic herbs for joint health. Analysis gives 25% protein, 15% fat, 2.5% fibre, 6.5% ash, 1.2% calcium and 1.1% phosphorus, and it's sold here as a complete food.

• Protein 25%, fat 15%, fibre 2.5%, ash 6.5%
• Calcium 1.2%, phosphorus 1.1%
• Poultry, 14% chicken
• Cereals: wheat and rice
• Green-lipped mussel and ayurvedic herbs included for joint support
• 4KG bag

On the numbers. Dr John's own composition text states 14% chicken, while their separate marketing description quotes a different figure for the same chicken content — the two don't match, so treat the 14% analytical figure on this card as the one to rely on rather than the marketing copy.

Who it's for: owners of sporting or working dogs needing genuinely high protein and fat levels alongside a joint-support ingredient, in a smaller bag size suited to trying the formula or feeding a single dog.
