Purina Pro Plan Veterinary Diet HA (Hypo/Hydrolyzed) Vegetarian Formula Dry Dog Food - 11.33kg

The Gold Standard Elimination Diet — When You Need Answers

Identifying a food allergy in dogs requires an elimination diet trial — and that trial is only as clean as what goes into your dog's mouth. Purina Pro Plan Veterinary Diet HA (Hydrolyzed) uses a single, hydrolyzed protein source processed to a molecular weight below the threshold that triggers most food allergic immune reactions.

• Hydrolyzed soy protein — clinically proven effective for most food-allergic dogs
• Available in Chicken Flavour, Salmon Flavour, and Vegetarian Formula for variety during long trials
• Corn starch as the sole carbohydrate — eliminates common grain allergens
• Complete and balanced — suitable for long-term feeding as management diet
• Prescription required — for use under veterinary supervision only

For elimination trials: HA must be the only food given for 8–12 weeks. This includes treats, dental chews, flavoured medications, and table scraps — any cross-contamination invalidates the trial.
