The human animal isn’t the only one affected by allergies. Like you, your adult dog can suffer from allergic reactions to any number of things—in the air, on his skin, and in his food. Allergies must be diagnosed and treated by your veterinarian, but first, you must know what to look for.
The most common signs and symptoms of allergies include:
The most common allergy symptoms in dogs are the skin reactions, regardless of the cause. And they can they can crop up at any age. Just because he didn’t have allergies as a puppy, doesn’t mean your dog won’t have them now that he’s an adult. Inhalant, food, contact, and flea allergies are four of the most common types of allergies that might affect your dog.
Inhalant allergies in dogs are caused by the same common allergens that affect you—dust, grass, trees, mold, pollen, ragweed, etc. They can be seasonal or persistent and, while some breeds (especially short-snouted breeds) might experience the same sniffly, sneezy symptoms you might suffer, skin reactions are most common. Inhalant allergies often can be treated with the same medications you take, but please don’t treat your dog’s allergies without veterinary supervision.
Food allergies can be the most difficult to diagnose and manage. Treatment involves a hit-and-miss approach involving a restricted diet and the gradual reintroduction of possible allergens to determine the culprit. Skin reactions to food allergies are common in dogs, but frequent vomiting or diarrhea also can be a sign. Keep in mind that if there is a change in your dog’s diet (or he just ate something he wasn’t supposed to), he might experience an episode of vomiting or diarrhea, but this doesn’t necessarily mean your dog has an allergy. Watch and see if it becomes a persistent problem before scheduling a costly trip to the vet.
Contact and flea allergies generally cause skin irritation and are treated topically. You might be surprised to learn that most dogs are only vaguely bothered by fleas. But those that are allergic can suffer—and so can their owners. Dogs with contact and flea allergies often chew their skin raw, leading to hair loss, odor, and infection, so fastidious flea control is a must.
Allergies can vary from dog to dog, so it is important that you work with your vet to make sure your dog gets the best possible treatment. You’ll both be happier for it.
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 |
