Can Dogs Develop Allergies Later in Life and What to Expect

Dogs can develop allergies later in life, which can be triggered by a variety of factors, including changes in their environment, diet, or even a new pet in the house.

According to research, the most common allergies in dogs are food allergies, which can cause symptoms such as itching, scratching, and digestive issues.

New allergies can arise in dogs as young as 5 years old, but it's more common for them to develop between 7 to 10 years old.

Some dogs may experience a sudden onset of symptoms, while others may develop allergies gradually over time.

Allergies can affect dogs of any age, breed, or mix, and some allergies are even inherited, so it's a good idea to ask about allergies and other immune disorders in relatives when getting a puppy from a breeder.

Dogs can develop allergies later in life as their immune system becomes sensitized to a particular allergen and starts to overreact to repeat exposures.

Allergies often appear as a young adult, and your dog can also be allergic to more than one thing.

Allergies in dogs can be triggered by a variety of factors, including food, insect bites, pollen, fungal spores, and even certain surfaces.

Your dog may be exposed to allergens through her food, insect bites, inhaling pollen or fungal spores, or even from brushing up against or lying down on a particular surface.

Some breeds are more prone to allergies due to a genetic component, with terriers, such as the West Highland White Terrier, Retrievers, Pugs, and Bulldogs being over-represented.

Dog allergies can be classified in several ways, including by the allergen and route into the body.

Flea saliva and chicken are common allergens in dogs.

Atopic dermatitis is one of the most common categories of dog allergies, characterized by skin lesions and other skin issues.

Respiratory allergies are another category, causing symptoms such as coughing and sneezing.

Food allergies make up the third main category, with symptoms including gastrointestinal issues.

Anaphylaxis is a severe and immediate allergic reaction that can occur in dogs.

Delayed allergic reactions can also occur in dogs, causing symptoms to appear hours or days after exposure to the allergen.

Dogs can develop allergies at any age, and it's essential to recognize the signs and symptoms to ensure they receive proper treatment.

Itchy skin is one of the most common signs of dog allergies, with about 80% of dogs suffering from itchy ears and 61% experiencing itchy feet, according to one study.

A skin sign of food allergies is usually itchiness, which appears the same as itchiness due to other allergies. It's often referred to as "ears and rears", but it can be more widespread, affecting areas like the groin region, armpits, and eye regions in about 35% of cases.

Dogs with food allergies may also experience gastrointestinal (GI) signs, such as loose stools, vomiting, and belching, with an average of three a day. Secondary ear and skin infections often arise from self-inflicted trauma from scratching and chewing.

Here are some common symptoms of dog allergies:

In some cases, dogs may experience anaphylactic shock, a rare but dangerous condition characterized by increased heart rate and difficulty breathing.

Dogs can develop allergies later in life, and it's not uncommon for them to experience symptoms for the first time in their senior years. Food allergies are usually a chronic condition and often don't involve an immunological response, but can still affect a dog's physical wellbeing.

Common signs of food sensitivity include diarrhea with or without vomiting, poor skin or itchy coat, and chronic ear or foot infections. Identifying the offending agent is crucial in managing food sensitivities, and a veterinary dermatologist may recommend intradermal skin testing or blood testing to identify allergens.

Treatment options for dog allergies include medications like steroids and Apoquel, which can provide relief for severe symptoms. However, the most important thing is to avoid problematic ingredients, and sticking to a hypoallergenic diet can help alleviate symptoms.

Here are some common treatment options for dog allergies:

Food allergies and sensitivities can cause a range of health issues in dogs. A true food allergy is a rare and immediate immunological response, often resulting in anaphylactic shock or severe dermatologic signs.

A food sensitivity, on the other hand, is a chronic condition that doesn't involve an immunological response, but can still cause significant health issues. These can include diarrhea, poor skin or itchy coat, and chronic ear or foot infections.

Some common signs of food sensitivity include diarrhea with or without vomiting, poor skin or itchy coat, and chronic ear or foot infections.

Atopic dermatitis is a common health issue in dogs, triggered by allergens such as pollen, dust, dust mites, mold, fleas, shampoo, cleaning products, and carpet fibers. The symptoms can be localized or affect the entire body.

Atopic dermatitis can cause skin irritation, ear infections, and secondary bacterial infections. Insect and arachnid bites and stings can also trigger acute allergic reactions, such as flea allergy dermatitis.

Here are some common symptoms of atopic dermatitis:

Treatment options for atopic dermatitis include immunotherapy, corticosteroids, allergy medications, and fatty acid supplements.

Treatment for dog allergies involves managing the immune system's over-reaction and modifying the environment to reduce exposure to allergens.

Intradermal skin testing is the gold standard for identifying allergens, which involves injecting small amounts of different allergens under your pet's skin to evaluate the immune system response.

Blood testing is also available, which identifies allergens via antibody levels.

Limiting environmental exposure is crucial, which can be done by using HEPA filters, vacuuming, washing bedding, cutting back weeds, and limiting time outdoors during allergy season.

Frequent bathing and wiping your dog's fur and feet with a medicated shampoo or wipe can minimize absorption of allergens.

Fatty acids in liquid or capsule form can act as anti-inflammatories and reduce signs of dog allergies, but too much can cause problems with blood clotting and wound healing.

A safe dose of fatty acids for dogs is between 20-55mg combined EPA and DHA per pound of body weight.

Medications such as Apoquel, diphenhydramine (Benadryl), loratadine (Claritin), and cetirizine (Zyrtec) can be used safely in dogs, but check with your vet for the appropriate dosage based on your pet's size and allergy severity.

Immunotherapy, also known as hyposensitization or allergy shots, can be an effective treatment option, with 50% of dogs seeing significant improvement in symptoms and 75% not needing as much medication.

Corticosteroids such as prednisone can be used to relieve severe symptoms, but they come with potential side effects and should be used short-term.

Cytopoint injections can relieve itching by binding directly to the substances that transmit itch signals to the brain, lasting four to eight weeks.

Removing pollen and other plant materials can limit contact with your dog's skin and the possibility of inhaling or swallowing them.

Baths can provide relief, with medicated shampoos resolving secondary infections on the skin and some shampoos helping to restore normal skin health.

Testing your dog for allergies can be a bit of a process, but it's worth it to figure out what's causing their discomfort.

There are a few different types of allergy testing for dogs, including intradermal skin testing, blood testing, and elimination diet trials.

Intradermal skin testing involves small injections of different allergens and monitoring for reactions. This information is then used to create a custom allergy serum.

Blood testing is less invasive, requiring only a blood draw, but can be less reliable than skin testing.

An elimination diet trial is the gold standard for testing food allergies, involving a diet with novel ingredients for 8-12 weeks, followed by gradual introduction of foods to determine the cause of the allergy.

Here are the three main types of allergy testing for dogs:

Each of these methods has its own advantages and disadvantages, and your vet will help you decide which one is best for your dog.
