Hill's Science Plan Medium Breed Mature Adult 7+ Chicken Dry Dog Food

When medium breed dogs reach 7 years of age, their bodies begin to change. Metabolism slows, joints may stiffen, and vital organs need more nutritional support. Hill's Science Plan Medium Breed Mature Adult 7+ with Chicken is formulated to address these age-related changes with precision.

Balanced minerals support heart, kidney, and bladder health - the organs most affected by ageing. Glucosamine from crustacean shell and chondroitin from cartilage help maintain comfortable joint function, while omega-6 fatty acids and vitamin E keep the skin nourished and the coat looking its best.

The recipe provides carefully calibrated protein and energy levels to maintain your senior dog's vitality without contributing to excess weight gain. Easy-to-digest ingredients including dried beet pulp and flaxseed support healthy digestion in ageing systems.

Suitable for medium breed dogs from 7 years of age. Available in 2.5kg, 6kg and 12kg bags, and pairs well with Hill's wet food for added variety and hydration.

This recipe is now upgraded with ActivBiome+ Multi-Benefit Technology: a prebiotic blend of oat bran and fructo-oligosaccharides (0.6%) that supports healthy digestion, a strong immune system and vital organ health.

When should I switch my dog to this mature adult formula?

Medium breed dogs are generally considered mature adults from around 7 years of age. At that point, their nutritional needs change and they benefit from the age-specific support in this formula. Transition gradually over 7 days.

How is this different from the standard adult formula?

This mature adult formula has adjusted protein and calorie levels suited to a less active metabolism, plus specific nutrients to support vital organ health (heart, kidneys, bladder) and joint comfort with glucosamine and chondroitin. These are not included in the standard adult formula.

What pack sizes are available?

Canine & Co stocks this food in 2.5kg, 6kg and 12kg bags. The 12kg bag offers better value for medium breed dogs.

Can I mix this with wet food?

Yes, mixed feeding is especially beneficial for older dogs as it adds extra hydration. For a 20kg dog, feed 1 can of Hill's wet food (370g) plus 150g of dry food daily.

Is there a lamb & rice flavour available?

Yes, we also stock Hill's Science Plan Medium Breed Mature Adult 7+ Lamb & Rice for dogs who prefer an alternative protein source. Both flavours provide the same age-specific nutritional support.

Does this food help with joint stiffness?

This formula includes glucosamine and chondroitin, which help maintain healthy joint function and comfortable mobility. If your dog has significant joint issues, consult your vet who may recommend a therapeutic diet.

What other senior dog options does Canine & Co stock?

We carry Hill's Science Plan Mature Adult in multiple breed sizes and flavours, plus the Senior Vitality range for dogs who need extra cognitive and energy support. Browse our collection for the full senior range.
