03
Digestive Support
Probiotics and prebiotic fiber improve stool quality and gut health.
04
Omega Fatty Acids
Essential for skin barrier and coat; EPA/DHA sources are best.
05
Large Breed Formulas

Living With It
Care, Cost and Maintenance

Mix new food with old over 7-10 days to avoid digestive upset.
Read Ingredient List

Frequently asked questions
How do I know if my large dog has a food allergy?
Common signs include chronic itching, ear infections, diarrhea, or poor coat. Work with your vet to rule out environmental causes first.
Can I switch between these foods if one doesn't work?
Yes, but introduce each new food over 7-10 days. Wait at least 4-6 weeks to judge effectiveness.
Are grain-free diets better for allergies?
Not necessarily. Many dogs are allergic to protein, not grains. Our picks include both grain-inclusive and grain-free options.
How much should I feed my large breed dog?
Follow the feeding guide on the bag, adjusting for activity level. Start at the lower end and monitor weight.
Do these foods require a prescription?
No, all picks are over-the-counter. For severe allergies, your vet may recommend a prescription hydrolyzed diet.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
