Animal Food Allergies May Be More Common Than We Think

Experts at the European Academy of Allergy and Clinical Immunology (EAACI) say we might be underestimating the prevalence of lactose intolerance and other food allergies among our furry friends. They published their report in the journal Allergy.

Rates of allergies and other autoimmune conditions are climbing in countries around the world. The cause of this increase is not totally clear, although many studies suggest that our sterilized environments and processed diets may be damaging our microbial ecosystems.

But it’s not just our bodies that are itching (or cramping, or wheezing). It’s Fido’s, and Fluffy’s, and Mr. Ed’s, too, says lead author Isabella Pali-Schöll of the University of Veterinary Medicine Vienna.

"Not only humans but basically all mammals are susceptible to developing allergies, as their immune system is capable of producing immunoglobulin E," Pali-Schöll said in a statement.

Immunoglobulin E (IgE) is an antibody released when the body meets an allergen. It’s meant to help keep us safe. The problem is that when we have allergies, our immune systems mistake harmless foods like wheat, eggs, milk, peanuts, or seafood for deadly poisons. The flood of IgE can cause hives, difficulty breathing, nausea, and anaphylaxis.

Most people with allergies are diagnosed because they decide to see a doctor about their symptoms. Animals don’t have that option (and probably wouldn’t go even if they did). The report, which reviews what we know and don’t know about our pets’ food allergies, finds that their reactions can be harder to spot.

“The true prevalence of food allergy in dogs, cats, and horses is unknown,” the authors write. Estimates vary widely depending on how the animal was diagnosed; studies have found that food allergies may affect anywhere between six and 25 percent of dogs, and 0.22 and 22 percent of cats. “In horses,” they write, “there is only anecdotal evidence with few cases documented in peer-reviewed literature.”

Diagnosing a pet’s allergies is not unlike diagnosing a person’s, except that the patient can’t describe his or her own symptoms. Veterinarians often use an elimination diet to determine the root of the pet’s problems.

"During this period of diagnosis, the animal will be fed homemade food or diet food prescribed by a veterinarian. Only then, and if there have not been any dangerous allergic reactions before, can 'normal' food be gradually reintroduced,” Pali-Schöll said.

As with human allergies, the best treatment is often just to avoid problem foods altogether. Most commercial pet foods are made with grains, meat, and soy products, which means this may be harder than it sounds, but a healthier, happier pet is worth it.

Scientists are working to develop medicines that will knock pets’ allergies out altogether. "The first few trial phases have already achieved some success,” Pali-Schöll said. “But it will take several more years for any products to see market launch and standard application.”

The bottom line, the authors concluded, is that we’ve still got a lot more to learn about how—and how commonly—these conditions affect our animal companions.

Fiona the Hippo Is Now on Cameo

Fiona the Hippo has earned her status as a celebrity. Born prematurely and weighing just 29 pounds in 2017, she became a sensation when she beat the odds and survived. Now, the Cincinnati Zoo's most beloved resident is taking her famous mug to Cameo.

Cameo is a service that allows fans to pay for personalized video messages from various celebrities. Most celebrities on the website are people, but that hasn't stopped Fiona from offering her star presence to the public.

For $100, you can request a custom video from the Cincinnati Zoo starring Fiona. A zoo staff member will recite the message while filming Fiona being adorable in her enclosure. One example video shows Fiona hanging out with her mom and snacking on some lettuce while her caretaker wishes the recipient a happy birthday.

Animal lovers who pay for a Cameo from Fiona will be supporting a good cause, too. Proceeds from the purchase will go to the Cincinnati Zoo, which is currently operating at limited capacity due to the COVID-19 pandemic. If you have a Cameo account, you can request your own video message for $100 here.

This isn't the first time the Cincinnati Zoo has used Fiona's popularity as a fundraising tool. Earlier this year, the zoo started selling the dung left behind by Fiona and other animals as garden fertilizer.
