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 |
Bloat is a life-threatening condition that acts rapidly and can lead to death within hours if not recognized and treated immediately. Unfortunately, the cause of bloat remains unknown at this time.
The scientific term for bloat is gastric dilatation-volvulus or GDV. Bloat is characterized by rapid and abnormal expansion of the stomach with gas (dilatation). This can be followed by rotation of the stomach (volvulus). This rotation closes both the entry to and exit from the stomach. The blood vessels also are closed down, and blood flow is restricted.
What follows is an increase in pressure inside the stomach and compression of the surrounding organs. Eventually, shock will occur as a result of the restricted blood flow. Here are a few key facts about bloat:
Bloat is a true medical emergency, and early identification and treatment is critical to survival.
In the early stages of bloat, the dog will be very uncomfortable. You might see him pacing and whining or trying unsuccessfully to get into a comfortable position. He might seem anxious, might lick or keep staring at his stomach, and might attempt to vomit, without success.
Other indications of bloat can include weakness, swelling of the abdomen, and even signs of shock. Signs of shock are increased heart rate and abnormally rapid breathing.
If you notice these signs, call your veterinarian immediately!
These suggestions could help you prevent bloat in your dog. However, they are based on suspected risk factors and are not guaranteed to prevent the onset of bloat.
Another way you might help prevent bloat is to feed a high-quality, highly digestible food with normal fiber levels.
Feeding management offers the best method available for reducing risk until the exact cause of bloat can be identified. Although not 100% effective, these measures can reduce the number of dogs that face this serious, life-threatening condition.
