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.

Is your dog really a finicky eater, or could it be something else? There are many factors to consider when you notice that your dog doesn't seem to be eating as usual.
If you're suspicious, take a closer look at exactly what he's eating each day. Does he get the occasional dog treat, or is someone sneaking him extra table scraps?
When you feed your dog a balanced, highly nutritious diet, nothing else is needed. In fact, extra treats can drastically alter your dog's normal intake of dog food. It's similar to the feeling you get after eating too much candy or potato chips. Are you interested in a full meal? Neither is your dog.
IAMS™ dog foods are nutritionally balanced and specifically formulated to meet the needs of dogs in all life stages, and with different lifestyles. There are dry, canned, and pouch varieties, plus options for senior or overweight pets, puppies, and dogs with reduced activity levels. Talk to your veterinarian or an IAMS Pet Care and Nutrition Center professional for advice on what's best for your dog.
Recommended feeding amounts are shown on every package. The guidelines are general suggestions for the amount of food you should feed your dog. Every dog is different and does not need the same amount of food. Your dog's activity level and his metabolic makeup are the determining factors. Start with the amount given in the feeding guidelines. Then, add or subtract food as you observe your dog's eating habits and weight.
Portion-Controlled Feeding: Divide the daily amount and feed at specific intervals. It is important to take away all leftover food after 15 to 20 minutes. This sets a pattern for your dog to follow. The portion-controlled feeding method is recommended for giant and large breeds as well as for overweight dogs. Portion control also works well for dogs with special needs.
Free-Choice Feeding: Feed the daily amount and let your dog eat at leisure. This method is recommended for use only with dry foods. Remember, dogs eat to meet their energy requirements. They quickly define their own daily portions when eating free-choice.
Water: Regardless of which food you choose to feed, your dog must have plenty of fresh, clean water. A good dog feeding tip is to place the water 3 to 5 feet from the food. This will help prevent your dog from gulping water and air in addition to food.
Routine: Dogs need it. Feeding at the same time and place every day establishes a comfortable eating pattern.
