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.

Hi, I'm Dr. Katy Nelson with IAMS, and today we're going to talk about how to take care of your puppy. First and foremost, you want to understand and meet your puppy's needs. Here they are in order of importance. Number one: basic health-- water, nutrition specifically formulated for puppies, and sleep. Also, immunizations and regular checkups are recommended. Number two: safety. As with small children, you need to keep your puppy in an environment that is safe for him. Puppies explore with their mouths, and they learn about different textures by gnawing. Also, chewing helps massage their gums. For your puppy's safety, keep things that he or she should not be chewing on out of reach. Number three: psychological. Your puppy's greatest psychological need is to be part of a group and be socialized with other dogs. However, to do this successfully, you need to be a guardian he can depend on. Once your puppy's basic needs are met, you want to understand the way he sees the world, so that you can build a strong relationship. Your puppy does not understand the world you live in, so you cannot expect him to. Two things you need to understand is that to them, everything is edible, and they will lunge at anything exciting—you, kids, guests, and other animals, until you train them not to. Praise him exuberantly to encourage the right behavior. Give him treats, pet him, play with him, and be stern to discourage the wrong behavior—ignore him, stop petting, or stop playing. Most importantly, be patient and consistent. Don't be harsh. Puppies have lots of energy, and it's healthy for them to use it. Periodically, helping your puppy release energy will minimize his urge to dig and chew on things. Spend time out in the yard making him run in short bursts. Go on walks or play fetch. Puppies are used to playing with their brothers and sisters. When they're separated, they're looking for their next playmate. Playing with your puppy will also make him more focused on you, improving your bond and making training easier. It teaches him new behaviors, self-control, and will help him gain self-confidence. Like play, socialization is also fundamental to raising your puppy. This is why socializing your puppy as soon as you bring him home is important for both of you. Socialization teaches your puppy to be calm in stimulating circumstances, and to obey when instructed. It also gets him used to being touched, handled, and even used to having hands and inedible things in and near his mouth, so that he behaves around other people, kids, and his veterinarian. Also, know that puppies are sensitive. They can read facial expressions and emotions. Be consistent about what things your puppy does that make you express happiness. Also, be careful not to give your puppy reason to think he's at blame for negative emotions you have from other areas of your life, like when you've had a bad day at work. Emotions are contagious. The happiest puppies tend to be in the most positive and loving households. I'm Dr. Katy Nelson with IAMS, and I hope that you found this helpful as you welcome your new addition to your family.
