Eukanuba Large Breed Mature & Senior is a dry food for large-breed dogs (25–40kg) from around 6 years of age and giant breeds (over 40kg) from about 5 years. Big dogs age faster than small ones, and this formula is built around the joint, weight, skin and dental issues that tend to arrive first in the bigger frames.

Poultry protein leads the ingredient list to support ageing muscle, with a controlled fat level to help older, less active dogs hold a healthy weight. Glucosamine and chondroitin sulfate feed the cartilage in hips, elbows and knees, while omega fatty acids target coat condition and skin comfort. The 3D DentaDefense kibble is shaped to reduce tartar as the dog chews, and added antioxidants and vitamins support immune function into the senior years.

Owners reach for this formula when a large-breed dog is slowing down, stiffening up, or starting to grey around the muzzle, but is still eating well and doesn't need a prescription diet. It covers the main age-related bases in a single bag.
