🔍 Cross‑Species Allergies Explained

Yes, dogs can develop an allergy to cats. Just like people, dogs may react to proteins in cat dander, saliva, and urine. While uncommon, veterinarians recognize this phenomenon and diagnose it similarly to other animal allergies.

⚠️ Common Symptoms to Monitor

• Skin irritation or hives where the dog touches the cat.
• Persistent itching, ear shaking, or redness in the paws/face.
• Respiratory signs—sneezing, watery eyes, or nasal discharge may occur.

🩺 How Diagnosis Works

Your vet may:

• Eliminate more common causes (fleas, food, environmental allergens).
• Use skin or serum allergen testing that includes cat proteins.
• Consider a controlled exposure trial—carefully monitored—with limited interaction.

🚫 Management & Control

• Reduce exposure: keep pets separated, restrict cat-free zones, and clean regularly with HEPA vacuums.
• Optimize airflow: HEPA filters and frequent bedding washes help minimize dander.
• Frequent grooming/bathing of both pets to reduce allergens on skin/fur.

💊 Treatment Options

• Antihistamines or corticosteroids for mild-to-moderate reactions.
• Targeted allergy meds—like Apoquel or Cytopoint—may provide comfort.
• Allergy immunotherapy (shots or drops) can build tolerance if a cat allergy confirmed.

🔚 Final Thoughts

Though not common, cat allergies in dogs can cause real discomfort. A proper diagnosis—using testing and exclusion—lets you customize a plan. Environmental controls, careful pet management, and medication or immunotherapy can help your dog comfortably share space with feline friends 🌟.
