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 |
Your new puppy's first meals at home are very important. Find out what formula your puppy has been eating, and continue feeding this food for a day or two after you bring him home. If you want to change his diet to a premium food such as IAMS™ ProActive Health™ Smart Puppy Original , gradually move him to the new formula and help avoid intestinal upsets by using the following steps:
Day 1: Fill your dog's bowl with 75% of his old food and 25% of IAMS ProActive Health Smart Puppy Original.
Day 2: Mix his former food and IAMS ProActive Health Smart Puppy Original in a 50/50 ratio.
Day 3: Feed your dog a mixture that's 75% IAMS ProActive Health Smart Puppy Original and 25% former food.
Day 4: Feed 100% of IAMS ProActive Health Smart Puppy Original.
To feed a puppy from weaning to 4 months of age, offer a 100% complete and balanced premium puppy formula. To determine each serving size, start with the daily amount recommended by the feeding guidelines on the pet food label, and divide that number by the number of times a day (usually three times) you plan to feed your puppy.
Serve the food at room temperature and remove the bowl within 30 minutes after he's done eating. After four months, you can feed a puppy twice daily on a regular schedule.
Don't add nutritional supplements to your dog's diet. Adding commercial dietary supplements or 'people food' such as hamburger, eggs, cottage cheese, or cow's milk is unnecessary and might even do more harm than good.
