Common Pet Allergy Symptoms + Medicine and Supplements to Support Your Furry Friend

July 6th, 2021

Just like their human companions, dogs and cats can suffer from allergies too. Whether it’s seasonal itchiness in the summer heat, year-round food sensitivities, or a coat that needs extra TLC, this guide breaks down how to help pets with allergies, including some of the most common symptoms to look out for, plus natural remedies to offer relief.

What are pet allergies?

The formal definition of pet allergies (described by the animal hospital network VCA) is “a state of over-reactivity or hypersensitivity of the immune system to a particular substance called an allergen.” Types of allergies can range, but there are three main culprits to be on the lookout for: skin, food, and environmental.

How do I know if my pet has allergies?

It’s a common question even for the most seasoned pet parents. If you start to notice any unusual behavior such as scratching, itching, or digestive problems, Dr. Linda Simons, MVB MRCVS recommends keeping a symptom diary. “You may notice a pattern. For example, those who have the most symptoms in the summer may have pollen allergies. Conversely, those who itch all year round could be allergic to their diet.”

No matter the allergy, getting to the root cause of it will be important for the long-term health of your pet, so plan to work closely with your vet to make a plan. In her practice, Dr. Simons finds that allergies, secondary skin infections, ear infections, and anal gland infections go hand in hand. “We frequently find that pets are suffering from more than one condition when they are presented to us. This is why it’s so important to have them seen by a vet for a full check over.”


Common Allergies in Pets

According to the American Kennel Club, skin allergies (aka dermatitis) are the most common types of allergic reactions in dogs and can cause a variety of symptoms. Some dogs are allergic to flea saliva, which can result in extreme itchiness. Food allergies or ingredient sensitivities (see below) can also lead to itchy skin or GI upset. And dust, pollen, and mold can cause atopic reactions that are often the result of seasonal allergies that crop up at certain times of year.

Cat allergies are also common, especially from flea saliva. Dr. Joanna Woodnutt, MRCVS, on the veterinary advisory board at Miss Cats, shares that “usually, pet owners will see their cats licking and chewing at their back or scratching their neck. Further investigation usually reveals lumps and bumps in a rash, some of which may bleed or get infected.” Cats can also be allergic to inhaled allergens, like pollens and dander, which may be a cause of feline asthma.


Common Food Allergies for Cats and Dogs

The most common dog food allergy symptoms are:

  • Itchy skin
  • Digestive upset (vomiting or diarrhea)

While these are obvious signs, more subtle changes like weight loss, lack of energy, and hyperactivity can also be signs that something is amiss. If you notice any of these symptoms, take a closer look at your pet’s diet. Although any ingredient has the potential to be an allergen, a few are most common than others:

  • Dairy
  • Beef
  • Lamb
  • Chicken
  • Chicken eggs
  • Soy
  • Gluten

Cats with food allergies may experience year-round itching and skin inflammation. Pay close attention to areas like the face, ears, groin, belly, and legs and paws. Pet’s may overgroom these areas, leading to potential hair loss. In addition to skin issues, some cats may experience digestive problems like having frequent bowel movements. Ingredients that most often cause food allergies include:

  • Beef
  • Fish
  • Chicken
  • Dairy

How to Help Pets With Food Allergies

For pets with diagnosed food sensitivities or allergies, Dr. Stacy Choczynski Johnson, DVM recommends a hydrolyzed hypoallergenic diet, which might require a vet prescription. Hydrolyzed food “is broken down to be so small that the immune system does not react to the allergen.” If you buy large bags of food, Dr. Choczynski Johnson has a tip: “Package it in small ziplock bags, or even put them in the freezer. Dog food can grow grain storage mites, which can also induce allergies.”

If you’re interested in a DIY approach and want to cook meals yourself, Dr. Simons suggests working with a nutritionist. “This is because creating a diet plan at home can commonly result in a pet developing nutritional deficiencies.” You’ll want to create a diet rich in whole food ingredients like salmon, vegetables, and sweet potato.

If you suspect your pet has a food allergy, you and your vet can run a food trial experiment (usually for between 6 and 8 weeks), followed by a food challenge, which introduces proteins back into their diet to see how they respond. (In order to run the experiment, you’ll need to feed your pet a diet that doesn’t include any proteins they’ve been exposed to previously, often referred to as “novel proteins.”)

It may be tempting to cycle through all the possible options out there in search of the secret recipe that solves pet allergies for good. From freshly cooked meals you keep in the fridge to novel proteins like rabbit, there are many routes to take, but you’ll likely save time, money, and stress by working closely with your vet to make a plan that works for you and your furry family member.


Environmental Allergies in Pets

Just like pet parents, seasonal allergies can impact dogs and cats too. Common environmental allergens include:

  • Pollen
  • Grass
  • Weeds
  • Mold
  • Fungi
  • Flea saliva

Symptoms of environmental allergies may include:

  • Itchy skin
  • Watery eyes
  • Sneezing
  • Hair loss
  • Scratching one or both ears
  • Paw licking
  • Saliva staining (fur turns yellow or orange)

Holistic Remedies for Allergies in Cats and Dogs

While underlying causes likely need to be addressed (don’t hesitate to make an appointment with your vet!), there are also lots of natural remedies available that can help your pet feel more comfortable.

  • Oatmeal: Oatmeal is believed to soothe dry skin, making it a popular addition to many pet shampoos and creams. You can also grind oatmeal in a blender and add it to your pet’s bath for a soothing soak.
  • Omega-3s: Although fish oils alone won’t relieve itching—your pet may need medication—Dr. Woodnutt explains that a defective skin barrier attracts allergens, so “giving fish oils high in omega-3 and 6 provides important nutrients to help the skin barrier, therefore reducing the allergens that get into the system.”
  • Coconut oil: From cooking to skin treatments, coconut oil is a pantry workhorse. When solidified, try rubbing it into the coat and skin to help soothe and soften skin. With your vet’s guidance, you can also add a small portion to your pet’s meal for added nutritional benefits.
  • Baking soda: When it’s bath time, add some baking soda to the tub to help soften dry skin and reduce itching. Try making a paste of 50% baking soda and 50% water. Apply it to your dog’s skin and rinse after 20 minutes.
  • Probiotics: Probiotics aren’t just for us—incorporating one into your pet’s diet may help their digestive health.
  • Regular paw cleanings: Dr. Simons recommends using a damp cloth to wipe your pet’s belly and paws when they come in from outside. “This removes excess pollen and grass from their fur.” You can also soak your pet’s feet in an epsom salt bath.
  • Laundry: Keep your pet’s bedding fresh by cleaning blankets, pillows, and coverings weekly with hypoallergenic laundry detergent.
