If your dog won’t stop scratching or your cat suddenly seems extra sneezy, they’re not alone. Allergies are a big issue for pets in Arizona, and the triggers often change with the seasons. From desert blooms to dust storms, our environment has a way of keeping pets on edge year-round.
The tricky part, though, is that allergy symptoms can often look like other health problems. Knowing what’s common in each season can help you spot the difference between a passing irritation and something that needs your vet’s attention.
Common Allergy Symptoms in Pets
Dogs and cats have their own versions of the watery eyes and runny nose that people get from allergens. With pets, you might notice symptoms like:
- Constant scratching, licking, or chewing at the skin
- Red, irritated ears or frequent ear infections
- Sneezing or nasal discharge
- Paw licking or biting
- Hair loss or hot spots
- Scooting or stomach trouble
If the symptoms last for more than a few days, it’s worth a call to your vet. Allergies are uncomfortable on their own, but if left untreated, they can lead to skin infections, ear infections, or even weight loss if your pet stops eating.
Spring and Fall = Pollen Trouble
Spring and fall bring out pollen from blooming flowers, trees, grasses, and weeds. For many pets, pollen time is prime allergy season. Dogs might chew on their paws or rub their faces after walks outside, while cats may start sneezing if they spend time near open windows.
Think of it like seasonal hay fever—but instead of sniffles, your dog might be up all night scratching, or your cat may start grooming so much they cause bald spots to appear.
Summer = Dust and Bug Bites
Arizona summers bring monsoons and dust storms. These seasonal storms can stir up mold spores and other irritants that affect pets even when they stay indoors. When you add in insects like fleas, ticks, and mosquitoes that thrive in the heat, your pet might be itching for more than one reason. If your dog comes in from the yard itching, or your indoor cat has red, irritated skin, it might be an allergic reaction.
Winter = Dry Air
Arizona winters may be mild, but they’re also very dry. Some pets develop itchy, flaky skin that looks like dandruff. Others might sneeze more often because of indoor irritants like dust or even scented candles. If your cat seems less interested in grooming or your dog has dull, fur and flaky skin, it may be more than just changes in their “winter coat.”
What You Can Do to Help
A few small changes at home can help you ease your pet’s allergy symptoms:
- Wipe paws and coats after walks to remove pollen and dust.
- Bathe your pet with a gentle shampoo to soothe itchy skin.
- Use air purifiers indoors to cut down on dust and other allergens.
- Keep up with flea prevention even in cooler months.
- Schedule a checkup if your pet has a flare-up.
When to Call Your Vet
Antihistamines, special diets, or prescription medications can make a big difference for pets who struggle with seasonal allergies. If your pet is keeping you up at night with scratching, losing patches of fur, or getting ear infections, it’s time to come in. Allergies don’t usually resolve on their own, but with a little help, your pet can relax comfortably again.
