A dog or cat with allergies usually itches rather than sneezes: paw licking, red ears, face rubbing and scratching at the belly or tail base are the common signs. Book a visit when itching keeps your pet up at night, comes back every season or leads to ear or skin infections. Petfolk SouthPark is a veterinary clinic in Charlotte, North Carolina, where our veterinarian in SouthPark works out whether the cause is fleas, food or the environment, because each needs a different fix.

What do allergies look like in dogs and cats?
At Petfolk SouthPark, the allergy signs the doctors see most are itch-related:
Licking or chewing the paws, often with rust-colored staining on light fur
Red, smelly or waxy ears, or ear infections that keep coming back
Rubbing the face on carpet or furniture
Scratching the armpits, belly or the base of the tail
In cats, over-grooming that leaves thin or bald patches, or small crusty bumps along the back and neck
Constant scratching breaks the skin, and bacteria and yeast move in. An allergic pet often arrives with a skin or ear infection on top of the allergy, and both need treatment.
Why is my dog itchier in spring and fall in Charlotte?
Pollen is the usual reason. A UNC allergy expert told WRAL that tree pollen is the worst allergen in North Carolina and ragweed the most notable in fall; that comment was about people, but pets react to the same pollens.
Petfolk's own records show the same pull: across Petfolk's Charlotte-area clinics, itchy skin made up about 14% of sick visits from June to September versus 11% from December to February (October 2025 to September 2026). Itch that follows the seasons points toward an environmental allergy. Itch that stays the same all year points toward food, house dust mites or fleas.
Is it allergies, or is it fleas?
Rule out fleas first. Flea allergy dermatitis is one of the most common skin allergies in dogs and cats, and a single bite can set off days of itching. You may never see a flea, because an itchy pet grooms them away; itch focused on the lower back and tail base is the classic sign. Year-round flea control for every pet in the home is often step one, and the flea and tick prevention page compares the options.
How do vets test pets for allergies?
No single test covers every allergy, so the Petfolk SouthPark doctor works through them in order.
Skin and ear checks. Tape and swab samples looked at under the microscope show whether yeast or bacteria are adding to the itch.
Flea control. Every pet in the home, for long enough to judge.
Food trial for food allergy. Your pet eats one prescription or novel-protein diet, and nothing else, for about 8 weeks. Blood and saliva tests sold for food allergy are not reliable.
Allergy testing for environmental allergy. Pollens, dust mites and molds are diagnosed from the history and exam once fleas and food are ruled out. A blood (serum) allergy test then picks the ingredients for allergy shots or drops.
Across Petfolk clinics, 86% of allergy testing and immunotherapy orders are for dogs, and about 6 in 10 allergy testing orders (61%) are a combined test-and-treatment package (October 2025 to September 2026). The doctor will also say whether a veterinary dermatologist referral would help.
What treatments help an itchy pet?
Most allergic pets at Petfolk SouthPark need a combination, adjusted through the seasons:
Fast-acting itch relief, as a daily tablet (Apoquel) or a long-acting injection (Cytopoint)
Medicated shampoos and wipes to clear pollen and yeast from the skin
Treatment for any skin or ear infection already present
Omega-3 fatty acids to support the skin barrier
Allergen immunotherapy, shots or drops made from your pet's test results, for long-term control
At Petfolk SouthPark, more than 1 in 4 visits for itchy skin (27%) left with Cytopoint or Apoquel (October 2025 to September 2026). Allergies are usually managed, not cured; the aim is a pet who sleeps through the night and stops chewing. The American Veterinary Medical Association has more on pet skin care, and the skin conditions page covers hot spots and hair loss.
How much does an allergy visit cost at Petfolk SouthPark?
At Petfolk SouthPark, an itchy pet is seen at an exam, and any tests, medicines or allergy panel are priced on top. You get an estimate before any treatment.
When is an allergic reaction an emergency?
A sudden reaction is different from seasonal itch. Go to a 24-hour emergency hospital if your pet's face or muzzle swells fast, hives spread across the body, or your pet vomits, collapses or struggles to breathe after a sting, a vaccine or a new food. Mild facial puffiness with normal breathing can often be seen the same day at Petfolk SouthPark, which is open 8 AM to 6 PM, seven days a week, so call first.
