Learn the signs that indicate your dog may need a hypoallergenic diet, when to consider a prescription option like Calibra VD, and how to transition safely.
Quick answer
Switch to a hypoallergenic dog food when your dog shows persistent signs of food intolerance—like itching, ear infections, or digestive upset—and your vet has ruled out other causes. A prescription diet such as Calibra VD Hypoallergenic with novel proteins (rabbit and insect) can help identify triggers and manage symptoms.
Why novel proteins matter in hypoallergenic diets
Standard dog foods often contain common allergens like chicken, beef, or dairy. Hypoallergenic diets use novel protein sources—ingredients your dog hasn't eaten before—to reduce the chance of an immune reaction. Calibra VD Hypoallergenic uses rabbit and insect protein, both considered novel for most dogs, making it a smart starting point for an elimination diet.
Frequently asked questions
- What are the most common signs of a dog food allergy?
- Chronic itching (especially paws, ears, or rear), recurrent ear infections, hair loss, hot spots, and loose stools or vomiting. These symptoms often appear gradually and may not respond to standard treatments.
- How long should I try a hypoallergenic diet before seeing results?
- Most vets recommend a strict 8- to 12-week trial. During this time, feed only the hypoallergenic food and plain water—no treats, chews, or flavored medications. Improvement in skin and digestion can start within 2–4 weeks, but full benefit may take the entire trial period. Keep a symptom diary to track changes week by week.
- When should I use a prescription hypoallergenic diet instead of an over-the-counter option?
- Prescription diets like Calibra VD are formulated to be nutritionally complete and strictly controlled to avoid cross-contamination with common allergens. They are the right choice when your dog has moderate to severe symptoms, when over-the-counter diets haven't helped, or when your vet suspects a true food allergy rather than a sensitivity. Always consult your veterinarian before starting a prescription diet.
