Abstract: The invention provides methods and devices for evaluating and tracking canine physical activity by determining for a canine (1) the duration of an activity or exercise; the speed of the activity or exercise based on the type of activity or exercise pace, e.g., walking, trotting, cantering, or running; a breed category factor to accommodate speed differences in distance travelled because of differences in body size and stride length; and an age factor and (2) calculating physical activity points (PAP) for the canine using an equation designed to accept input for the variables in (1) and use those variables to calculate PAP. The results from the equation are used to evaluate the physical activity of the canine and, based upon the evaluation, alter, if required, the canine's physical activity in a way that benefits the canine, particularly the canine's health.

Abstract: Methods for the reduction or prevention of oxidative stress in an animal comprising administering to the animal an effective amount of a composition comprising astaxanthin and/or Vitamin E are described. Also described are compositions comprising astaxanthin and/or Vitamin E, the compositions being effective for the reduction or prevention of oxidative stress in an animal.
