How Food Sensitivities Show Up as Skin or Digestive Issues

Food is more than just fuel for our pets—it can directly affect their health and comfort. At 108 Avenue Animal Hospital, we often see dogs and cats with unexplained itching, vomiting, diarrhea, or chronic ear infections, and food sensitivities are sometimes the hidden culprit. Understanding how these sensitivities manifest and what to do about them can make a huge difference in your pet’s quality of life.

What Are Food Sensitivities?

Food sensitivities occur when a pet’s immune system reacts negatively to specific ingredients in their diet. Unlike food allergies, which can trigger severe immune responses, sensitivities tend to cause chronic, low-grade issues. Common ingredients that may cause reactions include:

  • Beef, chicken, or dairy
  • Wheat, corn, or soy
  • Artificial additives, preservatives, or coloring

Food sensitivities can develop at any age, even if your pet has tolerated the same food for years.

Signs That Food Sensitivities May Be Affecting Your Pet

Pets with sensitivities often show symptoms that seem unrelated to food, making them tricky to identify. Common signs include:

Skin-Related Symptoms

  • Itching, scratching, or licking paws excessively
  • Red, inflamed, or flaky skin
  • Chronic ear infections or odor
  • Hair loss or thinning coat

Digestive Symptoms

  • Vomiting or regurgitation
  • Diarrhea or soft stools
  • Gas or bloating
  • Sudden changes in appetite

Some pets may exhibit a combination of skin and digestive symptoms, which can make pinpointing the cause challenging without veterinary guidance.

How Veterinarians Identify Food Sensitivities

At 108 Avenue Animal Hospital, we take a step-by-step approach to identify food sensitivities:

  • Medical history and diet review: Understanding what your pet eats and when symptoms occur
  • Rule out other causes: Parasites, infections, or other diseases can mimic food sensitivities
  • Elimination diet trial: Feeding a limited-ingredient or novel protein diet for several weeks to see if symptoms improve
  • Reintroduction test: Gradually reintroducing ingredients to confirm which foods trigger reactions

This structured approach allows us to accurately identify sensitivities while minimizing unnecessary dietary restrictions.

Managing Food Sensitivities

Once a food sensitivity is identified, managing it often includes:

  • Switching to a novel protein or hypoallergenic diet
  • Avoiding treats or table scraps that contain trigger ingredients
  • Using supplements like omega-3 fatty acids to support skin and coat health
  • Regular monitoring to track improvements in symptoms

Consistency is key—even small amounts of a trigger food can cause symptoms to return.

When to Call the Vet

Contact your veterinarian if your pet shows:

  • Persistent itching or scratching
  • Chronic ear infections
  • Ongoing vomiting, diarrhea, or digestive upset
  • Hair loss or skin lesions

Early intervention helps prevent secondary infections and ensures your pet stays comfortable and healthy.
