Just like in humans, allergies in dogs can be extremely irritating, and potentially life-threatening. It can dramatically impact their daily life and become a cause of worry for pet owners too. But, determining whether a dog is suffering from food allergies can be tricky because they often produce symptoms that are similar to environmental allergies. However, as a responsible pet parent, it’s vital that you’re aware of some common symptoms of food allergies in dogs.

Chronic ear infections

Yeast infections, ear mites, and swimmer’s ears are some common causes of ear infection in dogs. But, if the condition continues throughout the year, it’s a sign that you’re unknowingly feeding them something they’re allergic to. Typically, dogs with ear infections require more than two or three treatments in a year. You may often find them shaking their head and scratching at the irritated ear. The ear infection may look like black or brown build-up and can be very stinky. Even if you clean their ears several times a week, the infection may re-appear soon.

Itchy skin

Also known as allergic dermatitis, itchy skin is one of the most common symptoms of food allergies in dogs. It can happen anywhere in the body and makes your dog feel irritated most of the time. In most cases, itchy skin occurs in paws, their rear end, stomach, and ears (because of ear infections). But how do you know your dog’s skin is itching more than normal? If you see them persistently chewing on their paws, rear areas, or rubbing their body against surfaces, it’s a sign their skin is highly irritable.

Hives

Hives, also known as urticaria, look like itchy red bumps on the skin. These bumps are more noticeable if your dog has short hair; if not, you will have to touch them and find out. Hives usually develop within 6 to 24 hours of the consumption of allergic food. Just as itchy skin, hives can force your dog to scratch, bite, and lick the affected area, which may lead to broken skin and hair loss.

Digestive issues

Digestive problems are more serious symptoms of food allergies in dogs. Certain foods can trigger vomiting and diarrhea, sometimes within a couple of hours of consumption. Your dog may also look bloated and release gas more frequently. Digestive problems can be mild, moderate, or severe. These symptoms can also be caused by other illnesses like colitis and inflammatory bowel disease. If the symptoms are acute, it’s recommended that you take your dog to the vet as soon as you can.

Respiratory distress

Very rarely do dogs develop respiratory problems because of eating something. Respiratory issues, such as coughing, sneezing, wheezing, and labored breathing, are often signs of allergic reactions due to other factors. That said, some dogs might develop such problems after eating certain foods. Respiratory distress can be mild or severe. If your dog doesn’t seem to be breathing normally, contact your vet immediately, or take them to a pet clinic directly.
