Allergy Testing & Management Services
in
New Haven

For the dog or cat who can’t get a break. Diagnostic workups for environmental, food, and contact allergies — and long-term management plans that actually work, including immunotherapy when indicated.

Dog and Cat Vaccinations

Just like us, pets can develop allergies to almost anything at almost any time. Allergens can include environmental such as dust mites, grasses, and pollen. Allergens can also be diet related, such as certain proteins and vegetables. Allergy reactions in pets can range from gastrointestinal problems to skin problems to combinations of multiple problems amongst multiple body systems.
Managing allergies can be tricky and costly, but VWCNH is committed to helping you and your pet discover the best way to get your pet the relief they need. If you believe your pet may be suffering from allergies, please set up an appointment to see one of our amazing Veterinarians.
In addition to treatment and management of allergies, VWCNH offers allergy testing through Heska laboratories, a trusted reference laboratory. Once your pet has been tested, the laboratory can create a specific list of your pet’s allergens to help our Veterinarians tailor their treatments and plans even more specifically to your pet’s unique health. Heska Laboratory can even generate individual and unique medications that are made specifically for your pet to help them deal with their allergies.

Signs Your Pet May Have Allergies

  • Itchy skin — scratching, licking paws, rubbing face
  • Chronic or recurring ear infections
  • Hair loss or red, inflamed skin
  • Hives or skin rashes
  • Recurring GI upset — vomiting, diarrhea, soft stools
  • Runny eyes or nose
  • Sneezing

VWCNH offers allergy testing through Heska Laboratories, a trusted reference laboratory. Once your pet has been tested, the laboratory creates a specific list of your pet’s allergens to help our veterinarians tailor their treatments and plans more specifically to your pet’s unique health.
Heska Laboratory can even generate individual and unique medications made specifically for your pet to help them deal with their allergies — this is known as allergen-specific immunotherapy (allergy shots or sublingual drops).
  • Allergen-specific immunotherapy (custom allergy shots or drops from Heska)
  • Prescription diets — Royal Canin, Hill’s, or Purina elimination or hydrolyzed diets
  • Apoquel, Cytopoint, or other medical management for itch control

Frequently Asked Questions

My dog scratches constantly but seems otherwise healthy. Is this allergies?
It could be — environmental and food allergies are among the most common causes of chronic itching in dogs. But skin disease from infection, parasites, or hormonal disorders can look the same. We’ll start with a full workup before assuming allergies.
A food allergy trial involves feeding a strict hydrolyzed or novel protein diet for 8–12 weeks — no treats, no flavored medications, no exceptions. It’s the only reliable way to confirm a food allergy. We’ll guide you through every step.
Heska serology testing is a blood test that screens for environmental allergens. It identifies what your pet reacts to and forms the basis for custom immunotherapy. Dietary allergies are diagnosed through elimination trials, not blood testing.
Environmental allergies are managed, not cured — but most pets with proper management have dramatically better quality of life. Immunotherapy can reduce sensitivity over time. Food allergies are managed by avoiding the trigger.

Itchy Pet? Let's Figure Out Why.

Most allergy cases are very manageable once we identify the trigger. Call to schedule a workup.
