Quick answer: Hill’s Science Diet Adult Chicken & Barley is a widely available adult dog food from a large manufacturer that employs veterinary nutritionists and conducts research, which are key things the WSAVA recommends looking for. Whether it’s right for your dog depends on your dog’s age, size, activity, health, and how well it does on the food. The best way to compare foods is by the nutritional adequacy statement, the manufacturer’s expertise and quality control, and your dog’s body condition, stool, and energy.
What to check on any dog food
- AAFCO statement: complete and balanced for “adult maintenance” (or all life stages)
- Manufacturer: employs qualified nutritionists, conducts research and feeding trials, and has strong quality control
- Calories per cup: to feed the right amount
- Contact information for nutrition questions
Marketing terms that don’t mean much
- “Natural,” “holistic,” “human-grade,” and “premium” don’t guarantee better nutrition
- Grain-free diets aren’t healthier for most dogs, and some have been linked to heart concerns under FDA investigation
Comparable options
- Adult formulas from other manufacturers that meet WSAVA guidance
- Large-breed adult formulas for big dogs
- Weight-management formulas for dogs that gain easily
Is it working?
- Healthy body condition and weight
- Firm stools
- Good energy and coat
Switch foods gradually over 7–10 days.
