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.

Diet plays a central role in your dog’s overall health and well-being, and it stands to reason that you want to provide your dog the best possible source of nutrition in the dog food you choose. But some nutrients, like L-Carnitine, may be unfamiliar or completely foreign. Learn more about this vitamin-like compound and how it can help your dog maintain a healthy weight.
Carnitine, or L-carnitine, is a vitamin-like compound made in the body from amino acids. It's found naturally only in animal-based protein sources. It has been used to help with fat metabolism in other species, and recent scientific studies show that it can help reduce weight in overweight dogs.
This water-soluble substance attaches to fatty acids, transporting them into cellular mitochondria, the part of the cell that converts fat into a usable form of energy. There, they are broken down through oxidation and converted to energy for all tissues, including the heart, liver, and skeletal muscles. Through this process, carnitine helps reduce the storage of body fat and the amount of fat in the bloodstream.
In a study conducted by The IAMS™ Company, overweight dogs were fed similar diets. One group was given a diet supplemented with L-carnitine while another group received a diet without supplemental L-carnitine.
After seven weeks, the group that received the diet without supplemental L-carnitine lost 1.8% body weight compared to 6.4% body weight loss from the group that was fed the L-carnitine supplemented diet. Likewise, body fat was reduced in each group by 2.4% and 4.6%, respectively.1 The study found that L-carnitine promotes loss of body weight and body fat in overweight dogs.
IAMS™ ProActive Health™ Adult Healthy Weight is formulated with L-carnitine that helps turn fat into energy, providing a path to help keep him fit for life.
