Types of Allergies in Chihuahua

Your Chihuahua might be susceptible to several allergies, each distinct from the others. The most common type are:

🐕Seasonal Allergies

Environmental allergens present at certain times of the year trigger seasonal allergy. Common seasonal allergens include pollen from trees, grasses, and weeds. These allergens can trigger an allergic reaction when they come into contact with the nose, eyes, or skin. 

Chihuahuas are particularly susceptible to seasonal allergies due to their small size and relatively large surface area-to-body ratio. It means they have more allergens per unit of body weight than larger dogs. As a result, Chihuahuas may experience more severe symptoms than other breeds of dogs. 

🐕Food Allergies

Food allergies trigger an adverse reaction to a protein or other substance in your dog’s food. While any meal might produce an allergic reaction, beef, chicken, soy, wheat, and corn are the most common culprits. A chihuahua with a food allergy may experience vomiting, diarrhea, and itchiness. 

Chihuahuas are also more prone to food allergies than other breeds of dogs. It is due to their small size and fast metabolism, which can make it difficult for them to process specific substances. As a result, even a tiny amount of an allergen in their food can trigger an allergic reaction. 

🐕Environmental Allergies

Environmental allergies, also known as atopy, are a common problem in Chihuahuas. These allergies occur when the dog’s immune system overreacts to things like pollen, dust, or mold. The allergen causes an immune response in the dog’s body, which can cause various symptoms, from runny eyes and sneezing to itchiness and skin irritation.

In some cases, environmental allergies can even lead to respiratory problems. If you suspect your dog suffers from environmental allergies, you must take them to a veterinarian for diagnosis and treatment. There are various ways to manage environmental allergies in dogs, including allergy shots, medication, and diet changes. With the right treatment plan, most dogs with environmental allergies can live happy and healthy lives.

🐕Contact Allergies

An adverse response to a substance that comes into contact with the dog’s skin causes contact allergies. Common triggers include shampoos, detergents, cleaning products, and even certain types of bedding.

The symptoms of a contact allergy can range from mild to severe and, in some cases, may even require treatment from a veterinarian. If you suspect your Chihuahua has a contact allergy, it is important to consult your veterinarian to determine the best course of treatment. 

Symptoms of Allergies in Chihuahua

The symptoms of Chihuahua allergies can vary depending on the type of allergy and the severity of the reaction. However, there are specific symptoms that your Chihuahua may be allergic to, which include:


The presence of irritants in the nose causes sneezing. When these irritants come into contact with the mucous membranes in the nose, they trigger a sneeze reflex. Sneezing is the body’s way of trying to remove the irritant and relieve the discomfort. 

👉Watery Eyes

Watery eyes are a common symptom of chihuahua allergies. The inflammation of the blood vessels causes them in the eye, which leads to increased blood flow and fluid retention. It can cause the eyes to appear red and irritated. 

👉Runny Nose

A runny nose occurs when the mucous membranes in the nose become inflamed. This inflammation can cause an increase in mucus production, leading to a runny or stuffy nose. 


The release of histamines in the body causes itching. When the dog’s immune system detects an allergen, it releases histamines into the bloodstream in an attempt to remove the allergen. This release of histamines can cause itchiness, redness, and swelling. 


Hives are a form of skin rash produced by histamine release. They appear as raised, red welts on the skin and can be itchy and uncomfortable. 


Vomiting is a common symptom of food allergies in dogs. It occurs when the allergen irritates the stomach and causes an inflammatory response. It can lead to nausea and vomiting. 


Diarrhea is another common symptom of food allergies in dogs. It occurs when the allergen irritates the lining of the intestines and causes an inflammatory response. It can lead to abdominal pain and diarrhea. 

👉Rubbing Face on Furniture or Carpets

Dogs with allergies often rub their faces on furniture or carpets to relieve itchiness. It can cause the fur around the face to become matted and tangled.

👉Ear infection

An overgrowth of yeast or bacteria in the ear canal is frequently the cause of ear infections. Allergies can cause this overgrowth by disrupting the average balance of microorganisms in the ear. In addition, allergies can cause inflammation and swelling in the ear canal, leading to pain and discomfort.


Wheezing is a high-pitched whistling noise caused by an obstruction in the airway. Allergies can cause this obstruction by causing the tissues in the airway to swell. It can lead to difficulty breathing and wheezing.

Ways to Diagnose Allergies in Chihuahuas

There are a few different ways your veterinarian can diagnose allergies in dogs. The most common methods include: 

  • Skin scrape: A skin scrape is a procedure in which the veterinarian takes a small sample of the dog’s skin and examines it under a microscope. It can help identify dust mites, yeast, bacteria, or other organisms causing an allergic reaction. 
  • Blood test: It is possible to measure the levels of antibodies in the blood by performing a blood test. When exposed to an allergy, the immune system creates antibodies. If the levels of antibodies are excessive, it may indicate that the Chihuahua is suffering from an allergic reaction. 
  • Elimination diet: An elimination diet is a type of food trial that involves feeding the dog a restricted number of ingredients to determine whether or not their symptoms improve. If the symptoms improve, it may indicate that the dog is allergic to one or more of the ingredients in their regular dog food. 
  • Allergy testing: To diagnose a dog’s susceptibility to various allergens, the Chihuahua will undergo exposure to small amounts of allergens via injections, skin prick tests, or intradermal tests. These tests can help to identify which allergens are causing an allergic reaction. 

Treatment: What Can I Give My Chihuahua for Allergies

Even though there is no treatment for dog allergies, there are a few things that you can do to alleviate the symptoms that your Chihuahua is experiencing. The most common treatment options include: 

🐾Anti-inflammatory Medication

Anti-inflammatory medication can help to lower swelling and inflammation. It can help to relieve some of the discomfort associated with allergies. 

However, it’s important to continue giving the medication even after the symptoms have resolved. Stopping the medication too soon can cause the symptoms to return. 


Antihistamines can help to relieve itchiness, sneezing, and runny nose. They work by blocking the action of histamine, a substance released in response to an allergen. 

There are various over-the-counter and prescription antihistamines available. Be sure to talk to your veterinarian before giving your dog any over-the-counter medication. 


Corticosteroids are a type of anti-inflammatory medication. It can be provided orally, by injection, or topically. Corticosteroids can help to relieve itching, swelling, and inflammation.

However, they can have various side effects, including increased appetite, panting, and lethargy. Before starting treatment, talk to your veterinarian about corticosteroids’ potential risks and benefits. 

🐾Allergen-Specific Immunotherapy

It is a treatment that desensitizes the dog to the allergens that cause allergic responses. It involves giving the dog small amounts of the allergen over time, which can help reduce the allergy’s severity.

🐾Nutritional Supplements

There are a few nutritional supplements that may help to relieve allergies in dogs. These include omega-3 fatty acids, probiotics, and vitamin E. 

Omega-3 fatty acids help in the reduction of inflammation. Probiotics can help to improve the balance of good and bad bacteria in the gut. Vitamin E is an antioxidant beneficial in reducing inflammation. 


There are a variety of shampoos and rinses available that can help to relieve itching and irritation. These shampoos typically contain ingredients that help to reduce the number of allergens in the hair. 

Several types of shampoo are available for dogs with allergies, so consult your veterinarian to see which one is ideal for your pet.

🐾Dietary changes

Ensuring your Chihuahua is on a healthy diet is important in managing allergies. A meal high in fat and protein can help reduce the severity of allergies. You should also avoid feeding your Chihuahua foods that contain artificial preservatives, flavors, and colors.

Another approach is to feed your dog a limited ingredient diet. It is a diet that contains only a few ingredients, which can help to identify which ingredient is causing the allergic reaction.

Q. Can my Chihuahua’s allergies resolve on their own?

The answer is dependent on the underlying source of the allergies. If the environmental factors trigger allergies, such as pollen or mold, they may improve when the weather changes, or it is no longer in contact with the allergen. However, continuing therapy is necessary if the triggers are food or medications. If you’re concerned about your dog’s allergies, it’s always best to consult with a veterinarian for guidance.

Q. Are allergies in Chihuahuas inherited?

There is no one answer to the question of whether or not Chihuahuas inherit the tendency to be allergic, although there is evidence to suggest that this may be the case. For example, if both parents are allergic to certain substances, there is a greater likelihood that their offspring will be allergic as well.

Additionally, allergies tend to run in families, so if someone in your family has allergies, it is more likely that you will also be allergic. However, it is essential to remember that not all allergies are hereditary, so even if neither parent is allergic, it is still possible for the puppy to develop allergies. The best way to determine if your puppy has allergies is to speak with your veterinarian and have them perform allergy testing.

Q. Can allergies kill my Chihuahua?

In severe cases, yes. Allergies can cause anaphylactic shock, which is a potentially life-threatening condition. If not treated immediately, anaphylactic shock can lead to death. If you fear your dog is having an allergic reaction, get veterinary assistance as soon as possible.
