Like humans, dogs are also highly susceptible to food allergies, and the symptoms can be quite horrifying. Although many pet parents go an extra mile to give a healthy life to their pets, there are certain symptoms of allergies in dogs that may go unnoticed at first.

Ranging from itchy skin to other dangerous consequences, the symptoms of food allergies vary from one pet to another. Here are some of the symptoms and triggers for food allergies in dogs that every dog parent should know about:

1. Excessive itching
Do you find your dog itching its fur all the time, even though it doesn’t have any tick or flea issue? Well, your dog might be allergic to some food items. These symptoms tend to occur regardless of the season. The most common food triggers are milk, soy, eggs, and gluten.

2. Hives
In addition to unusual itching, pet parents are often distressed because of hives in their furry pals. This is also considered one of the most common food allergies in dogs. Hives are a condition in which pale red bumps show up on the skin. The most common itchy spots are ears, paws, and rump. The symptoms of this allergy include red, scratchy bumps on your dog’s skin. The triggers are mainly harmful plants and chemicals, but common food allergens can also cause hives.

3. Swelling
If your dog ever ingests any food item that it is allergic to, then there is a maximum possibility of swelling in certain areas of its body. Grains are some of the most common food allergens that can cause inflammation in your dog’s body. Since the symptoms of food allergies can differ from one pet to another, you should always speak to your vet if you notice any unusual signs.

4. Gastrointestinal troubles
Many dogs develop stomach-related issues when they ingest food allergens. When it comes to gastrointestinal problems in dogs, the symptoms include vomiting, stomach ache, nausea, weight loss caused by vomiting and diarrhea, and constipation. These symptoms can either be a sign of a non-threatening ailment or be a grave danger. So, if you ever see any of these allergic reactions in your dog, then you must seek immediate medical intervention.

5. Behavioral changes
Behavioral symptoms can be hard to notice. These emotional and/or behavioral issues are accompanied by symptoms, such as loss of interest in food or activities, restlessness, social withdrawal, and constant itching against any surface or object, among many others.

Often, pet parents confuse food intolerance with a food allergy. Your dog might face some gastrointestinal issue in case of intolerance, while food allergies can lead to the development of other complications as well. When it comes to the treatment of such allergies, it is always beneficial to visit your vet for the right solution.
