Indeed, there are many things that both the chihuahuas and the chihuahua owners could have in common. For example, both chihuahuas and chihuahua owners could be prone to obesity if not regulating food intake and by not exercising.

In addition, chihuahuas and humans may also acquire diseases that result from improper dietary regimens like diabetes, heart diseases, etc.

Moreover, the most amusing thing that both chihuahuas and humans share is the fact that they are both vulnerable to allergies.

Sounds impossible? Think again.



Veterinary experts assert that chihuahuas have allergies too. One of the primary signs of allergies is the itching of their skin. Their respiratory tract system can also be affected by allergies.

Normally, chihuahuas will manifest symptoms of respiratory tract allergies like sneezing, wheezing, and coughing. Their nose and their eyes may also manifest a discharge just like humans do whenever they have colds or flu.

There are also allergies that may have an effect on their digestive system; hence, it may result in watery stools, diarrhea, or vomiting.

Experts say that almost 20% of the chihuahuas in the United States suffer from several types of allergy. So, for people who want to know more about the different allergies that chihuahuas acquire, here is a list of the most common allergies:

Allergies with flea

It is a well-known fact that chihuahuas are usually infected with fleas. However, what most people do not know is that they can get allergies through these fleas, too.

Well, it is not the fleas that actually cause allergic reactions in chihuahuas but the flea’s saliva. Hence, it is important for the chihuahua to undergo a skin allergy examination so as to determine if a particular chihuahua is sensitive to flea saliva.

In the event that the chihuahua is allergic to flea saliva, it would be better for the owner to implement a rigorous flea control or flea eradication treatment in order to lessen the allergic reactions. Though, it must be kept in mind that solutions that are used in flea control should be safe to the chihuahuas.

Allergies pertaining to foods

Like humans, chihuahuas get allergies from food as well. There are instances wherein chihuahuas get allergies from foods that their system cannot tolerate, such as wheat, soy products, pork, beef, whey, fish, eggs, milk, corn, artificial sweeteners, and chemical preservatives that are placed in their food.
Moreover, chihuahuas can get allergies in food that they have not tried before.

So, the best way to combat this particular allergy problem is to feed the chihuahua with the commercial chihuahua foods more often instead of homemade products.



Some signs of allergic reactions to food in chihuahuas are shaking of the head, scratching the ears, irritated skin, biting and licking at the rear feet, inflammations in the ear, sneezing, behavioral changes, vomiting, diarrhea, etc.

Atopic Dermatitis

Atopic dermatitis is a known allergic skin disease in chihuahuas. This usually caused by the hypersensitivity of the chihuahua’s immune system to ordinary substances that can be found in the environment like molds or dust mites.

Usually, a chihuahua is said to be suffering from atopic dermatitis when the chihuahua begins to excessively lick and chew its paws, licking the abdomen and its rear feet.



Atopic dermatitis can be seen as a saliva staining found in the armpits, between the toes of the paws, and in the groin. In light-colored canines, atopic dermatitis can be seen as a red-brown stain found on the same parts that were mentioned.

Allergies resulting from bacteria

This is the most common cause of serious allergies in chihuahuas. Generally, there are certain bacteria that thrive in the chihuahua’s skin. This is known as the species of Staphylococcus bacteria. In most cases, this does not cause allergies in chihuahuas. However, there are certain types of chihuahuas that develop an allergy to it.

The most common symptom of this kind of allergy is hair loss along with the development of ringworm like marks in the chihuahua’s skin. The areas where these marks appear usually get infected, hence, it is important to treat them with antibiotics.



Indeed, allergies are not for humans only. Allergies great affects almost 20% of the total population of chihuahuas in the United States, and that is a pretty alarming number. Therefore, it is extremely important for chihuahua owners to know these chihuahua allergies so as to come up with some preventive measures at the first sign of the attack.
