Eukanuba Thriving Mature Large Breed Chicken at a glance:
This premium dry dog food is crafted for the unique needs of mature large‑breed dogs. Its high protein content fuels muscle maintenance, while glucosamine and calcium support joint health and bone strength. Antioxidants like vitamin C and E boost immunity, and a fiber blend promotes healthy digestion.
Designed with dental care in mind, the hexagonal kibble and DentaDefense formula help reduce tartar buildup and keep teeth clean—essential for older dogs who may struggle with oral hygiene. The inclusion of omega‑3 and omega‑6 fatty acids enhances skin and coat condition, giving your dog a shiny, healthy look.
