Dogs also react to certain foods and are allergic to them, just like humans. Food allergies in dogs can trigger various symptoms, from itchy skin and severe gastrointestinal problems to behavioral issues. While there is no cure for food allergies in dogs, they are typically manageable by avoiding the identified allergen. New pet parents need to have their furry children tested for allergies. This article lists the causes and types of food allergies in dogs.

Causes of allergies in dogs
Here are a few causes of allergies in dogs:

1. Immune system
Food allergies in dogs occur when the immune system misidentifies the protein as a harmful substance, causing inflammation in the body. This leads to physical changes in the dog’s body, such as redness, swelling, and itching.

2. Genetics
Although dogs can develop food allergies at any age, certain breeds, such as Labrador Retrievers, Golden Retrievers, Collies, and English Springer Spaniels, are prone to food allergies. Genetics may also determine whether a dog is more likely to develop a food allergy. If the dog’s parents or siblings have food allergies, they are at risk, no matter what breed they are.

Types of food allergies
Here are a few types of food allergies to know about:

1. Food
The most common cause of food allergies in dogs is consuming certain foods, mostly protein. The allergy appears suddenly after prolonged exposure to a food allergen. It is common for dogs to develop sensitivities to more than one ingredient over time. Some of the most common food triggers in dogs are:

2. Beef
Beef is a nutritious food for dogs, containing proteins, vitamins, and fatty acids. However, continually feeding beef can lead to the development of beef allergies. This is because the protein in the beef does not suit most dogs.

3. Dairy
The lactose in the milk can cause allergies in dogs. This is different from lactose intolerance, which has symptoms in the form of gastrointestinal problems. A lactose allergy is more serious, with symptoms such as itchy skin and rashes.

4. Wheat
Wheat is a healthy energy source, but some dogs have an allergic reaction to wheat grains. If wheat is the culprit, it is best to switch to alternative sources of carbohydrates.

5. Eggs
Dogs can have egg allergies, which means the dog’s immune system overreacts to the proteins in the egg yolk. Eggs can be present in most store-bought dog foods. Pet parents must read labels before buying foods that have eggs as an ingredient.

6. Chicken
A common ingredient present in packaged dog food is chicken. Chicken is also a source of nutritional protein. Still, in some dogs, the immune system may instigate an allergic reaction, leading to symptoms such as the appearance of rashes, itchiness, or changes in skin color.

7. Lamb
Dogs can also be allergic to lamb-based dog food, another nutritious source of protein. In rare cases, lambs do not agree with dogs and can cause various health problems.

8. Soy
Serious health issues may develop in dogs after consumption of soy, an edible bean with high protein content. It can lead to health issues such as liver disease and reproductive problems.

If a food allergy in dogs is left untreated, it can lead to more allergies, worsening symptoms, and a poor quality of life. The most reliable way to diagnose a dog’s food allergy is by eliminating certain foods under the vet’s supervision. Also, as a pet owner, it is crucial to read dog food labels closely to avoid feeding them anything they are allergic to.
