Fact Sheet

Relative Age of dogs or Cats, in Human Years

To use this table, find your pet's weight range in the top row of (white) cells. Then drop down to the row in which the left most cell (gray) contains your pet's actual age in years. The cell in which your pets weight range (top, white) intersects your pets age (left, gray) contains your pet's approximate age in people years.

Time flys! Especially if you've got four legs!

This table illustrates why it is important to begin to address the special needs of our middle aged and older pets, even before they're old enough to really seem middle aged or "senior" to us.
