Confused by the ingredient list on your kitten’s food? You’re not alone. Marketing pet foods that have “human-grade ingredients” is becoming commonplace. While appealing to many pet owners, it is important to be aware that the term “human grade” has no legal definition and is used primarily for marketing purposes.
Foods, typically meats, are labeled either as “edible” or “inedible, not for human consumption.” Once a food leaves the human food chain, even if it is of outstanding quality, it has to be labeled “inedible, not for human consumption.” Therefore, meats used in pet food must be labeled as “inedible,” regardless of the source or quality of the meat. The only way to make a pet food with ingredients deemed “edible” is to never let the meat leave the human food chain and actually manufacture the pet food in a human food facility and transport it using human food trucks. Therefore, advertising a product as containing “human-grade ingredients” is untrue if it is not manufactured in a human food facility. However, just because a pet food isn’t marketed as being “human grade” does not mean that the ingredients are poor quality.
As dogs age, changes occur in the way their bodies function, so it makes sense that what they eat also might need to change. The following list of health issues might be more common in aging pets.
Decreased Immune System Function
Throughout a dog’s life, a process called peroxidation occurs. Peroxidation is a normal process that the body uses to destroy cells that outlive their usefulness and to kill germs, parasites, etc. This process, however, also can destroy or damage healthy cells. As your dog ages, the damage caused by peroxidation accumulates, which, in turn, increases the risk of certain problems, such as infections.
Antioxidants are naturally occurring nutrients that help maintain overall health by neutralizing the peroxidation process of cellular molecules. Some antioxidants, such as vitamin E, beta-carotene, and lutein, are naturally occurring nutrients.
Recent research sponsored by The IAMS™ Company found that dogs fed a diet rich in antioxidants such as vitamin E, lutein, or beta-carotene had improved immune responses and vaccine recognition. This might be especially important in senior dog care; IAMS research has found that as dogs age, immune responses can decrease.
More Frequent Intestinal Problems
Older dogs might have higher numbers of unfavorable bacteria and lower numbers of beneficial bacteria in their intestines, which can result in clinical signs of gastrointestinal problems (e.g., diarrhea).
Feeding a diet containing fructooligosaccharides (FOS), a unique fiber source that helps nutritionally maintain healthy intestinal bacterial populations, promotes growth of beneficial bacteria. Beet pulp, a moderably fermentable fiber source, also helps maintain intestinal health by providing energy for the cells lining the intestine and promoting small, firm stools.
Different dogs show signs of aging at different times, and much of this variation is associated with size. Larger dogs generally appear 'old' sooner than smaller dogs. The table below lists the age at which various groups of dogs should be transitioned to senior foods, such as IAMS™ ProActive Health™ Senior Plus.
| Weight Range | Age to Begin Transition |
|---|---|
| More than 90 lbs | 5 years |
| 51 to 90 lbs | 6 years |
| 21 to 50 lbs | 7 years |
| Up to 20 lbs | 7 years |
