Recognizing the signs

Does your pet have allergies?

Allergies can look different in every pet. If scratching, ear infections, or skin issues keep coming back, an underlying allergy is often the cause — and early diagnosis makes a real difference in your pet’s comfort and quality of life.

Common symptoms to watch for

Here are the most common signs to watch for in dogs and cats. If you notice any of these recurring, it’s time for an allergy workup.

Persistent scratching, licking, or chewing

Red, inflamed, or thickened skin

Hair loss or thinning coat

Recurrent ear infections

Hot spots, skin sores, or scooting

Vomiting or diarrhea (food allergies)

If symptoms are ongoing or keep coming back, an underlying allergy is often the cause — and early diagnosis makes a real difference in your pet’s comfort and quality of life.
What’s causing it

What causes allergies in dogs and cats?

Allergies happen when the immune system overreacts to normally harmless substances. Many pets have more than one type of allergy, which is why accurate diagnosis is essential before starting treatment.

01

Environmental Allergies (Atopy)

  • Tree & grass pollens
  • Dust mites
  • Mold spores
02

Food Allergies

  • Chicken
  • Beef
  • Dairy
  • Occasionally grains or additives
03

Flea Allergy Dermatitis

A reaction to flea saliva — even a single bite can trigger a significant flare-up in sensitive pets.

04

Contact Allergies

  • Bedding materials
  • Cleaning products
  • Certain fabrics
Our approach

How we diagnose pet allergies

At Weldrick Animal Hospital, we focus on identifying the root cause rather than simply masking symptoms. Our step-by-step method allows us to build a treatment plan tailored specifically to your pet.

01

Comprehensive Physical Exam

A thorough nose-to-tail assessment to understand the full picture of your pet’s health and history.

02

Skin & Ear Cytology

Microscopic analysis to detect any infections that may be complicating the allergic response.

03

Flea Control Assessment

Ruling out or confirming flea allergy dermatitis as a contributing or primary trigger.

04

Food Elimination Diet Trial

A structured diet protocol to identify or rule out food-related triggers before other testing.

05

Allergy Testing

Targeted testing (when appropriate) to guide longer-term management, including immunotherapy options if needed.

Treatment options

Personalized plans for lasting relief

There is no one-size-fits-all solution for pet allergies. Every treatment plan is customized to your pet’s specific triggers, lifestyle, and long-term needs.

Medical

Medical Management

Anti-itch medications, targeted allergy therapies, and fatty acid supplementation to reduce inflammation and discomfort.

Nutrition

Dietary Therapy

Prescription hypoallergenic diets and long-term nutritional management for food-sensitive pets.

Prevention

Flea Prevention

Year-round flea control is essential — even in lower-risk seasons — to prevent flare-ups in allergy-prone pets.

Topical

Skin & Ear Care

Medicated shampoos, topical therapies, and ongoing monitoring with adjustments to keep flare-ups under control.

Our Goal

Long-term control, improved day-to-day comfort, and a better quality of life for your pet — with treatment plans that are practical, effective, and sustainable for your family.

Frequently asked questions

Pet allergy questions, answered

What are the most common allergy symptoms in dogs?
Itching, licking paws, recurring ear infections, red or inflamed skin, and hair loss are among the most common signs. Many owners notice their dog is constantly scratching or chewing at one area of their body.
Can cats develop allergies too?
Yes. Cats are just as prone to allergies as dogs. They often show it through excessive grooming, patchy hair loss, or skin lesions rather than the obvious scratching you’d expect in a dog.
How long does allergy treatment take to work?
It varies by pet and allergy type. Some pets show improvement within days of starting treatment, while others — especially those with environmental allergies — require ongoing management for the best long-term results. We’ll keep you informed at every step.
Are pet allergies curable?
Most allergies are not curable, but they can be very successfully managed with the right care. With a proper treatment plan, the majority of pets go on to live comfortable, happy lives with minimal flare-ups.
