Just like humans, dogs can develop allergic reactions to certain foods that are suitable for their system. If you’re a dog parent, you should keep an eye out for the common symptoms of food allergies in dogs, especially when you’re feeding them something new. Identifying these symptoms will help you prevent mild to severe pain and discomfort by getting immediate treatment for your pet.

1. Coughing, wheezing, and sneezing
If your dog is allergic to a particular ingredient, it activates the immune system once the food enters the GI tract. The body releases a chemical called histamine that can lead to coughing, wheezing, and sneezing. If you notice your dog showing these symptoms immediately after a meal, there is a high chance your pet is allergic to something in the food; consult a vet for guidance on further steps.

2. Ear itching and ear infections
Excess consumption of animal protein can lead to frequent ear infections in some dogs, which means you might notice your canine constantly itching its ears. Bacteria and yeast are naturally present in dogs’ ears, but they can cause infections if the right conditions are present. Certain foods can also lead to yeast infections and cause ear itching, which is a common symptom of food allergies in dogs.

3. Swollen face, ear flaps, and nose
Swelling is also a side effect of histamine production, and swelling of the ear flaps, nose, and face in dogs can indicate an immune response to a certain kind of food. Swelling in the tongue can sometimes lead to choking, which is dangerous, so it is recommended that you immediately check with your vet if you notice signs of swelling.

4. Skin issues
This is another common symptom of food allergies in dogs. Histamine production in the body as a result of food allergies causes hives, which are raised bumps on the skin’s surface that cause itching, redness, and pain. You may not notice hives if your pet has a thick fur coat, but you may see them scratching and biting the affected area continuously. You should not avoid this sign of food allergies in dogs.

5. Vomiting and diarrhea
Both vomiting and diarrhea are common signs of food sensitivity and food allergies in all pets. This is often the first sign of food allergies in dogs as the body tries to push the allergens out of the system.

6. Gastric problems
Gastric problems like flatulence, stomach pain, nausea, and bloating can all indicate a food allergy. Such GI issues can also develop due to other health issues, so it is best to talk to a vet and identify the cause early on.

Consult a vet and get the right treatment started early on if you notice any of these symptoms of food allergies in your dog.
