Can Dogs Be Allergic to Grass?

After spending time outside, do you hope your dog isn’t going to start sneezing, licking or scratching excessively—and wonder, Can dogs be allergic to grass? It’s a legitimate concern, since grass allergies are on the rise in pets. In this piece, we will cover everything you need to know about grass allergies in dogs, from causes and symptoms to effective treatments and prevention strategies.

Are Dogs Allergic to Grass?

Dogs, like humans, can become allergic to many environmental factors, and grass is one of the most common causes. Such allergies result from the dog’s immune system overreacting to benign substances, such as pollen from grass. When this occurs, the immune system releases histamines, which causes itching, sneezing and other allergic reactions.

Grass allergies are often seasonal, with symptoms ending with the time of year when grass pollen levels peak, usually in spring and summer. Some dogs do experience year-round allergies, particularly when they may also be allergic to other allergens in the environment such as mold, dust mites or trees.

Allergic Reaction to Grass in Dogs

However, the symptoms of grass allergies in dogs can range from mild to severe, depending on the dog’s sensitivity to the allergen. Common symptoms include:

  • Itchy Skin: The main symptom of grass allergies is itching. Dogs might lick, bite or scratch their paws, belly, ears and other affected areas. If left untreated, it can lead to hot spots or infections.
  • Sneezing and Coughing: Similar to other species, dogs may also develop sneezing and coughing, as a result of inhaled allergens such as grass pollen.
  • Watery Eyes and Redness: If you are allergic to grass, you can develop conjunctivitis, where your eyes become red and watery. Dogs can also paw their eyes when they are irritated.
  • Ear Infections: Grass pollen can irritate the ear canals, resulting in itchy, inflamed ears, ear infections, and excessive ear scratching or shaking.

Gastrointestinal Issues: In some cases dogs who have a grass allergy may show signs of vomiting, diarrhea or gastrointestinal upset (less common).

What Causes Grass Allergy in Dogs?

Grass allergies in dogs are triggered by several grasses that release pollen during growing seasons. The most common grass species responsible for allergic reactions in dogs include the following:

  • Ryegrass
  • Timothy Grass
  • Fescue
  • Kentucky Bluegrass
  • Bermuda Grass

In high pollen seasons, your dog might breathe these allergens or directly touch the grass, which aggravates the allergic response. The immune system responds by releasing histamines and other chemicals that cause the symptoms above.

How Grass Allergy in Dogs is Diagnosed

If you think your dog suffers from a grass allergy, it’s important to get an accurate diagnosis from your veterinarian. Here’s how the diagnosis process usually goes:

Physical Examination

Your veterinarian will do a comprehensive physical exam — looking for common signs of allergies, like itching, red skin, ear infections, or eye discharge. This examination can enable the vet to decide whether or not allergies could be a factor.

Allergy Testing

Your vet may suggest allergy testing to identify the specific allergens triggering the reaction. This can include:

  • Skin Testing: A small amount of various allergens (including grass pollen) is injected into the skin of your dog. Your dog will react to one or more of the allergens if he is allergic.
  • Blood Tests: This type of test measures your dog’s immune response to particular allergens. Blood tests are especially helpful when it comes to identifying environmental allergies, such as grass or pollen.

Ruling Out Other Conditions

It’s important to get checked for other health conditions that might mimic the symptoms of a grass allergy. These include:

  • Flea Allergies: Much like grass allergies, flea bites can cause itching and skin irritation.
  • Food Sensitivities: In addition to environmental allergens, certain food allergies can cause GI upsets, vomiting and diarrhea, leading to confusion over whether it may be an environmental allergy.
  • Skin Infections: Bacterial or fungal infections may cause itching, redness, and ear problems, which are often confused with allergies.

What to Do for Dogs with Grass Allergies

While you cannot cure your dog of a grass allergy (once diagnosed), there are several treatments available. Below we discuss both medical treatments and lifestyle changes you can make to help manage and reduce your dog’s symptoms.

Dog Grass Allergy Medications

Your vet might prescribe one or more of the following medications that can help relieve your dog’s allergies:

  • Antihistamines – These drugs work by preventing the actions of histamine, the chemical that produces allergic symptoms such as itching, sneezing, and swelling.
  • Corticosteroids: Steroids, including prednisone, can help relieve inflammation, itching, and swelling, particularly in more severe cases.
  • Allergy Shots (Immunotherapy): Allergy shots are a longer-term treatment option. They function by slowly desensitizing your dog’s immune system to particular allergens over time.
  • Antibiotics or Antifungal Medications: If your dog seems to have developed a secondary infection from rubbing or licking at the ears, antibiotics or antifungal medications may be indicated.

Self-Care and Home Remedies

Some natural home remedies and lifestyle changes can also help to minimize your dog’s exposure to allergens:

  • Limit Outside Activity: During peak pollen season, limit your dog’s time outdoors as much as possible and keep your outdoor activities to a minimum, particularly on windy days when pollen levels are at their highest.
  • Wipe Your Dog Down After Walks: After being outside, wipe down your dog’s paws and coat with a damp cloth to remove pollen. Try to bathe with a gentle, hypoallergenic pet shampoo to wash away any allergens.
  • Close Windows: During high pollen seasons, keep windows shut to prevent pollen from getting into your house.
  • Use HEPA Filters: Adding HEPA filters to your residence, particularly in rooms your dog frequents, can help reduce airborne allergens.
  • Avoid Bathing Too Frequently: While regular bathing with a mild, pet-safe shampoo can help soothe irritated skin and remove allergens from your dog’s coat, too much bathing can dry out the skin and lead to other dermatological problems.

Environmental Control

You can also lessen an allergic reaction by controlling your dog’s living environment. Here are some helpful strategies:

  • Establish a Grass-Free Zone: Set up grass-free zones for your dog to roam without pollen exposure.
  • Utilize Indoor Play Areas: If the pollen count is very high, create a designated play area indoors for your dog so they can still have fun without inducing an allergy attack.

Natural & Alternative Remedies

Other dog owners turn to alternative remedies for grass allergies. And although these should always be discussed with your vet before trying them, here are some natural options that may offer relief:

  • Omega-3 Fatty Acids: Omega-3 supplements, such as fish oil, are known to decrease inflammation and support the skin, and may also help dogs with allergies.
  • Local Honey: Dog owners have expressed success in feeding their dog local honey in order to build tolerance to local pollen, although there is no scientific evidence supporting this.
  • Herbal Remedies: Calendula, chamomile, and aloe vera can help with itching and inflammation when applied topically.

How to Prevent Grass Allergy in Dogs

Although you cannot prevent your dog from developing grass allergies altogether, you can take some precautionary measures to minimize the risk and manage any existing allergies:

Opt for Low-Allergenic Grass Types

If you’re planting grass in your yard, choose varieties that don’t release as much pollen. Some fescue or fine-leaf grasses generate less allergen than common grasses like ryegrass or Kentucky bluegrass.

Have a Healthy Immune System

A strong immune system can assist your dog in combating allergens more efficiently. Look out for a high-quality, well-balanced diet for your dog along with supplements like omega-3 fatty acids and probiotics to maintain overall health.

Monitor Seasonal Allergies

Keep track of local pollen forecasts and try to limit outdoor activities during high-pollen days, particularly if your dog is very sensitive to allergens.
