Don’t put your pet on senior food or a light diet because it is a certain age. Diets formulated with the older pet in mind frequently contain fewer calories, 18 percent protein and four to six percent fiber. Animals who will benefit from a diet with these characteristics are those with increased weight gain due to a decline in activity and those who suffer from frequent constipation.

The most frequent changes in the aging pet is the slowing of the metabolic rate, which lowers the animals energy requirement. An animal who requires less energy but continues to eat at the same rate of energy intake stores surplus energy as fat and becomes overweight.

This obesity imposes an extra strain on the heart or any aged bones and joints. In this case, it would be helpful to feed the animal either less food or a food which contains a reduced amount of energy per unit of weight.

Likewise, the need for dietary protein may decline because of a change in activity, a slowing down of metabolic activity and a diminished ability on the part of the kidneys to deal with the waste products of protein digestion.

Such an animal would benefit from decreasing the total protein intake. The gastrointestinal tract loses tone with increasing age so the stimulative effects of added fiber maybe also be useful.
It must be emphasized that diets with the above characteristics may not be appropriate of an older pet who is still very active. Likewise, special conditions which are present in your pet may require a special diet.

1989, the Canadian Veterinary Medical Association (CVMA) introduced standards for diets intended for older animals. The diet should contain no less than 18 percent protein of high quality, and 5 percent of fat. The energy level of the diet should maintain the normal weight of the animal. Products which meet these standards can n obtain the CVMA scale of certification.

Feed your pet according to its individual state and rate of activity. This can best be determined by first consulting your veterinarian and reviewing your pets individual health and nutrient requirements.
