Calibra Expert Nutrition Mobility review

Our verdict lands in the Good band, and the typical adult dry food finishes there as well. The named 45% chicken protein and the printed supplement doses do the earning, while the nutrition reads a shade more conventional, with estimated carbohydrate at 43.0% of dry matter running near the typical 46.2%. As a well made everyday food that happens to carry a serious joint payload, it does exactly what its name says.

Ingredients, as declared: chicken protein (45 %), rice (20 %), brewer's rice (10 %), poultry fat (8 %, preserved with tocopherols), apple pulp dried (5 %), hydrolysed poultry protein (4 %), yeasts, hydrolysed chicken liver, (2 %), salmon oil (2 %), fulvic acid (0.2 %), glucosamine (1,000 mg/kg), chondroitine sulphate (650 mg/kg), prebiotics (mannan-oligosaccharides 120 mg/kg, β-glucans 100 mg/kg, fructo oligosaccharides 70 mg/kg), dried rosemary & thyme (200 mg/kg), methyl sulphonyl methane (150 mg/kg), Boswellia serrata (90 mg/kg), Mojave yucca (80 mg/kg), Lactobacillus acidophilus HA - 122 inactivated (15 × 109 cells/kg).

Chicken protein at 45% leads. Behind it come hydrolysed poultry protein at 4%, hydrolysed chicken liver at 2% and poultry fat at 8% supplying energy. As across this range, the poultry entries name the category rather than the bird, the only loose thread on an otherwise specific label.

The starch comes from rice at 20% and brewer's rice at 10%, with dried apple pulp at 5% for gentle fruit fibre. Protein converts to 30.8% of dry matter and fat to 16.5%, an ordinary adult shape that leaves the joint work to the additions.

Those additions are the point. Glucosamine at a gram per kilo is a working dose, not label decoration. Chondroitin sulphate follows at 650 mg/kg, and MSM at 150 mg/kg adds the sulphur compound that usually partners them in joint blends. Boswellia serrata at 90 mg/kg is a plant resin with a long history in stiff-joint formulas. Mojave yucca at 80 mg/kg completes the set.

The marine omega 3s that joint recipes lean on come from salmon oil at 2%. The prebiotic trio of mannan-oligosaccharides, beta-glucans and fructo-oligosaccharides is dosed in print, with an inactivated Lactobacillus culture alongside.

Vitamins and organic trace minerals are fully itemised on the label, and fulvic acid at 0.2% is the range's signature curiosity, a plant-derived acid Calibra runs through the whole Expert Nutrition line.

£5.14 a kilo, packed in 2kg and 12kg bags.

Reckon on about 219 grams a day for a 15kg adult dog in moderate condition, which comes to roughly £1.13, using the standard estimate of around 840 kcal daily (110 × bodyweight^0.75). The label's table asks 170 grams for the same weight. Begin somewhere between the two and let condition steer.
