As the temperatures rise in Las Vegas, so does the risk of summertime allergens affecting our dogs and cats. While the longer days bring opportunities for pool parties and sunshine, our pets can suffer from seasonal allergies triggered by environmental changes that are particularly prevalent during the summer months. If your cat or dog has been excessively scratching, sneezing, or showing signs of skin irritation, it might be due to common allergens in the Las Vegas environment.
Here are the top summertime allergens to watch out for and how to help your pet stay comfortable and healthy through the season.
1. Pollen from Grasses, Trees, and Weeds
Despite Las Vegas being part of a desert climate, the city still has its fair share of landscaping, including allergenic grasses, ornamental trees, and desert weeds. Pollen counts are particularly high in the summer, especially from plants like mulberry trees, olive trees, ragweed, and Bermuda grass which are all common in the area.
Dogs and cats can react to pollen similarly to how humans experience hay fever. Symptoms can include itchy eyes, sneezing, inflamed skin, and excessive paw licking or ear scratching. Pets that enjoy spending time outdoors are especially vulnerable. To reduce exposure, try wiping your pet’s paws and fur with either a pet wipe, or a damp cloth after outdoor time. On high pollen count days, try to keep your windows closed to limit exposure.
2. Flea Bites and Flea Allergy Dermatitis
Summer is prime time for fleas, especially in a hot and dry climate like Las Vegas. Fleas thrive in warm temperatures and can be found in shady areas of your yard, dog parks, and even indoors if they hitch a ride on your pet.
Some pets are very sensitive to flea saliva, and a single flea bite can trigger Flea Allergy Dermatitis (FAD), a condition that causes severe itching, inflammation, and hair loss. You may notice your pet obsessively scratching or biting at its tail base, groin, or armpits.
To protect your pet, stick to a year-round flea prevention routine, such as topical treatments, oral medications, or flea collars recommended by your vet.
3. Mold Spores and Mildew
Although Las Vegas isn’t known for its humidity, monsoon season in late summer can bring sudden storms and temporary damp conditions. Mold and mildew can quickly develop in shaded garden areas, outdoor furniture, air conditioning units, and even inside homes with poor ventilation.
Mold spores are airborne and can cause allergic reactions in pets. If ingested, they can cause coughing, wheezing, itchy skin, or even digestive issues. If you notice these symptoms and you suspect mold, it’s essential to address potential sources. Clean regularly, and ensure your home has proper ventilation in bathrooms, basements, and outdoor areas to help minimize exposure.
4. Insect Stings and Bites
Insects like bees, wasps, and mosquitoes are common and potentially dangerous summertime allergens. They are not just a nuisance to humans, but they also pose a risk to pets. Curious cats and playful dogs may chase after buzzing bugs, resulting in stings on the face, nose, or paws. Some pets may experience mild reactions like swelling and redness, while others can suffer from severe allergic reactions, including hives, vomiting, or difficulty breathing.
Always monitor your pet after an insect sting, and seek immediate veterinary care if signs of anaphylaxis occur. If mosquitoes are present in your area, ask your vet about safe repellents or preventive treatments, especially since mosquitoes can transmit heartworm.

5. Chemical Irritants from Lawns and Gardens
During the summer, homeowners and landscaping services in Las Vegas often increase the use of fertilizers, herbicides, and pesticides. While these chemicals help keep lawns green and pest-free, they can be toxic to pets. Walking on freshly treated grass or licking their paws after outdoor activity can expose your dog or cat to these harmful substances.
Symptoms of chemical exposure can include drooling, vomiting, skin rashes, and lethargy. Avoid treated areas for at least 24–48 hours, and rinse your pet’s paws after walks. Consider using pet-safe landscaping products to minimize the risk altogether.
Helping Your Pet Beat the Heat and Allergies
Las Vegas may offer endless sunshine, but it’s also home to a host of summertime allergens that can take a toll on your pet’s health. From environmental triggers like pollen and mold to fleas and chemical irritants, it’s crucial to be proactive in preventing and managing allergic reactions. Keep an eye on your pet’s behavior, schedule regular vet checkups, and maintain a clean living environment.
If your cat or dog shows persistent symptoms of seasonal allergies, your veterinarian may recommend allergy testing or prescribe antihistamines, medicated shampoos, or other treatments. With a little awareness and care, you can help your pet enjoy the summer just as much as you do, minus the itching and sneezing.
