As pet owners, it is important to be aware of the various health issues that our furry friends might experience, including allergies. Just like humans, dogs can also suffer from allergies that can cause discomfort and other health issues. In this blog post, we will discuss the different types of allergies that dogs can have, their symptoms, and the possible treatment options.

Causes of Dog Allergies

Allergies in dogs are caused by the overreaction of the immune system to certain substances in the environment or in the food they eat. The most common types of allergies in dogs include:

  • Skin allergies: Can cause itchy skin.
  • Flea allergies: Some dogs are allergic to flea saliva, which can cause severe itching and skin irritation.
  • Food allergies: Some dogs can be allergic to certain ingredients in their food such as beef, chicken, wheat, or soy. Food allergies can cause vomiting and diarrhea.
  • Environmental allergies: Dogs can also be allergic to pollen, dust mites, mold spores, and other environmental factors.

Symptoms of Dog Allergies

The symptoms of dog allergies can vary depending on the type of allergy they have and the severity of the symptoms. Some common symptoms of dog allergies include:

  • Chewing or licking paws: Dogs with allergies may chew or lick their paws excessively due to skin irritation or itching.
  • Biting legs or tail: Some dogs may also bite their legs or tail due to the discomfort caused by allergies.
  • Diarrhea or dry heaving: Allergies can also cause digestive issues such as diarrhea or dry heaving.
  • Dry nose: Dogs with allergies may have a dry, cracked nose due to the inflammation caused by the allergy.
  • Sneezing: Just like humans, dogs can also sneeze due to allergies.
  • Red, itchy eyes: Some dogs may also experience red, itchy eyes due to allergies.

Treatment Options for Dog Allergies

If you suspect that your dog has allergies, it is important to consult with your veterinarian for proper diagnosis and treatment. Some common treatment options for dog allergies include:

  • Avoiding allergens: If your dog is allergic to certain environmental factors, such as pollen or dust mites, you can help reduce their exposure by keeping your home clean and free of allergens.
  • Changing their food: If your dog has a food allergy, your veterinarian may recommend switching to a hypoallergenic diet or eliminating certain ingredients from their food.
  • Medications: Your veterinarian may prescribe antihistamines, steroids, or other medications to help manage your dog’s allergy symptoms.
  • Benadryl: Benadryl is a common over-the-counter medication that can be used to treat dog allergies. However, it is important to consult with your veterinarian first before giving your dog any medication.
  • Fish oil supplements: Some studies have shown that fish oil supplements can help reduce inflammation and improve skin health in dogs with allergies.

Best Food for Dogs with Allergies

Food allergies are one of the most common forms of allergies in dogs. They occur when your dog’s immune system overreacts to certain substances in their diet, typically proteins or complex carbohydrates. Common food allergens for dogs include dairy, beef, chicken, chicken eggs, soy, and wheat gluten. If your pooch is allergic to any of these, they might experience itchy skin, digestive issues like vomiting or diarrhea, or even behavioral changes such as hyperactivity or aggression.

Food sensitivities are common, while allergies are less common but more severe

– Symptoms of food sensitivities include itchy skin and upset stomach

– Symptoms of food allergies include vomiting, diarrhea, and anaphylaxis

– Carefully read labels for ingredients that trigger reactions in your dog

– Try an elimination diet to identify trigger ingredients

– Consider adding Omega-3 fatty acids to improve skin health and reduce inflammation

– Consult with a vet nutritionist for tailored diets or supplements

– Be patient as finding the right diet may take time

If your dog has a food allergy, it is important to switch to a hypoallergenic diet that does not contain the ingredients they are allergic to. Some of the best foods for dogs with allergies include:

  • Grain-free dog food: Many dogs are allergic to grains, so switching to a grain-free diet can help reduce their allergy symptoms.
  • Hypoallergenic dog food: Hypoallergenic dog food is specially formulated to be free of common allergens such as beef, chicken, wheat, and soy.
  • Novel protein dog food: Novel protein dog food contains protein sources that are not commonly found in dog food, such as venison, duck, or rabbit.

Dog Allergies: Food List

If you suspect that your dog has a food allergy, it is important to eliminate the suspected ingredient from their diet. Here is a list of common allergens in dog food:

  • Beef
  • Chicken
  • Wheat
  • Soy
  • Corn
  • Eggs
  • Dairy

Skin Allergies and Itching

If your Havanese is constantly scratching and biting at their skin, it’s likely they’re experiencing some pesky skin allergies and itching. This can be caused by a variety of allergens such as pollen, dust mites or even certain foods.

It’s important to identify the cause of the allergy so that you can take the necessary steps to alleviate their discomfort. One way to determine what your dog may be allergic to is through an elimination diet. You can start by feeding them a simple diet of protein and carbohydrates for a few weeks before slowly reintroducing different types of food one at a time. Pay attention to any changes in their behavior or symptoms during this process.

Additionally, regular grooming and baths with hypoallergenic shampoo can help reduce allergens on your dog’s skin. If left untreated, excessive scratching and biting can lead to more serious issues such as infections from open wounds or hot spots on their skin.

In severe cases, medication prescribed by a veterinarian may be necessary to manage the allergies and provide relief for your pup. By keeping an eye out for signs of skin allergies and taking proactive measures, you’ll ensure that your furry friend stays healthy and comfortable all year round!

Managing Environmental Allergies in Pets: Supplements and Medications for Relief

Below are some common supplements and medications to manage environmental allergies in pets, providing relief and addressing symptoms such as itching, inflammation, and allergic reactions.

  • Omega-3 Fatty Acids: A popular supplement known for its anti-inflammatory properties, reducing itching and inflammation caused by allergic reactions. Available in fish oil capsules or liquid form.
  • Antihistamines: Commonly used medications that block the effects of histamine, the chemical released during allergic reactions. They can alleviate symptoms like sneezing, runny nose, and itchy skin. Remember to consult your veterinarian to ensure safe usage for your dog.
  • Corticosteroids: Prescribed for severe allergy cases, corticosteroids help reduce inflammation and itching. However, they should only be used under veterinary supervision due to potential side effects such as increased thirst, appetite, weight gain, and urinary tract infections. Weigh the benefits and risks with your veterinarian when considering corticosteroid treatment.
  • Consult Your Veterinarian: Always seek advice from your veterinarian before introducing any new supplement or medication regimen to address your dog’s allergy-related health needs.

Zyrtec for Dogs

Zyrtec, an over-the-counter human allergy medication, can also be given to dogs with atopic dermatitis or mild to moderate environmental allergies. Vets may recommend it for dogs who scratch excessively, are sensitive to insect bites or have dermatitis.

The recommended dosage of Zyrtec for dogs depends on their weight, and liquid Zyrtec may be easier to dose out for smaller dogs since the tablets are small and difficult to cut evenly. Zyrtec’s active ingredient, cetirizine, is closely related to hydroxyzine, a powerful antihistamine that’s sometimes used before surgeries to help patients relax.

Zyrtec is considered a second-generation antihistamine and doesn’t cause drowsiness like first-generation alternatives. Studies have found that Zyrtec reduced itching in 18% of dogs with atopic dermatitis, and dogs who took Zyrtec before being injected with histamine had less inflammation around the injection site than those who didn’t receive the drug. A separate study of 12 dogs injected with histamines found that the active ingredient in Zyrtec was notably more effective than Benadryl at minimizing the body’s immune response.

If there are any questions or concerns about the correct dosage of Zyrtec for dogs, it is best to consult with a veterinarian.

Allergy Testing for Dogs

Allergy Testing for Dogs: A Helpful Tool for Diagnosis and Treatment

If you’ve noticed your furry friend exhibiting signs of allergies such as excessive scratching, licking, or hair loss, it’s essential to consult with your veterinarian. Allergy testing for dogs can help identify the specific allergens causing your pet’s discomfort and create a treatment plan to ease their symptoms.

There are two main types of allergy testing for dogs: intradermal skin testing (IDAT) and serum allergy testing (RAST). IDAT is the most recommended test by veterinary dermatologists and involves injecting small amounts of allergens under your dog’s skin. A reaction at the injection site indicates an allergy to that specific allergen. However, IDAT requires your dog to be sedated or anesthetized and you might need to stop your dog’s allergy medication for at least two weeks prior to the test.

RAST, on the other hand, is a blood test that measures the levels of IgE antibodies in your dog’s blood. It can be done without sedation or anesthesia and can be performed by your regular veterinarian. However, RAST results can take up to six weeks to arrive.

Discuss with your veterinarian which allergy test is best for your dog to ensure they receive the most accurate diagnosis and treatment plan.


How do I know if my dog’s allergies are seasonal or year-round?

Do you ever wonder why your dog keeps scratching and sneezing? Well, it could be due to allergies.

But how do you know if your pup’s allergies are seasonal or year-round? One way to tell is by closely monitoring their symptoms.

If they only experience itching, sneezing, and other allergy-related issues during certain times of the year (such as spring or fall), then chances are they have seasonal allergies.

However, if their symptoms persist throughout the year regardless of season, then it’s likely that they have year-round allergies.

Knowing the difference can help you better manage your furry friend’s health and provide them with the appropriate treatments for relief.

Are there any natural remedies for treating dog allergies?

If your furry friend is experiencing allergies, you may be wondering if there are any natural remedies to help them feel better. Luckily, there are a few options that can provide some relief.

One common remedy is adding omega-3 fatty acids to your dog’s diet, which can reduce inflammation and itching. Another option is using coconut oil as a topical treatment for irritated skin. Additionally, washing your dog with an oatmeal-based shampoo can soothe their skin and alleviate symptoms.

Keep in mind that while these remedies may work for some dogs, it’s important to consult with your veterinarian before trying any new treatments.

Can allergies in dogs lead to more serious health problems if left untreated?

If you ignore your dog’s allergies, it could lead to more serious health problems. Allergies can weaken your dog’s immune system, making them more susceptible to infections and other illnesses.

In addition, allergies can cause chronic inflammation, which can damage organs over time. For example, if your dog has a food allergy and continues to eat the offending ingredient, it could result in intestinal damage or even pancreatitis.

So don’t take allergies lightly; if you suspect your dog is suffering from allergies, consult with your veterinarian as soon as possible to prevent any further complications.


Allergies in dogs can cause discomfort and other health issues if left untreated. It is important to be aware of the different types of allergies that dogs can have, their symptoms, and the possible treatment options. If you suspect that your dog has allergies, consult with your veterinarian for proper diagnosis and treatment. By taking the necessary precautions and providing proper care, you can help your furry friend live a healthy and happy life.
