pets age
much faster
than people

Because dogs and cats age more quickly than people do, major health changes can occur much earlier in their lives. Pets can be considered “middle age” when they turn 7 and “retirement age” at 11, and often develop many of the same age-related issues seen in older people.

aging happens
from the inside out

At Hill’s, we’ve been studying how nutrition impacts pets’ cell function for over a decade. We learned the aging process is complex, slowing pets down both mentally and physically.

  • Decreased expression of genes
  • Increased expression of genes

Compared to younger dogs and cats, older pets have different gene expression. This can affect how their bodies function, because some of those genes are associated with inflammatory processes, oxidative stress, immunity, DNA repair, energy production and protein metabolism.


Through our research we were able to identify these changes and develop Hill’s® Science Diet® Youthful Vitality.

HAVE YOU SEEN THE
TELL TAILS?

As your pet ages, they may begin to show some of these outward signs. But because these age-related changes can creep up slowly, just like they do with people, you might not realize it at first.

Have you noticed any of these signs of aging?

If so, it might be time to change your pet’s food or talk to your vet.
