Frequently Asked Questions
What is the best dog food for Cocker Spaniels?
For Cocker Spaniels, we recommend Blue Buffalo Life Protection. Look for a formula with high-quality animal protein as the first ingredient and an AAFCO feeding trial statement. Always transition foods gradually over 7–10 days.
How much should I feed my Cocker Spaniel?
A typical adult Cocker Spaniel weighing 20–30 lbs needs 1.5–2.5 cups per day depending on activity level. Use the bag’s guidelines as a starting point and adjust based on body condition score. You should be able to feel but not see the ribs.
Do Cocker Spaniels have food allergies?
Cocker Spaniels can develop food sensitivities, most commonly to proteins (chicken, beef) rather than grains. If you notice itching, ear infections, or digestive issues, discuss an elimination diet with your vet. Novel protein formulas (salmon, duck, venison) work well for sensitive Cocker Spaniels.
Is grain-free food good for Cocker Spaniels?
Unless your Cocker Spaniel has a confirmed grain allergy, grain-free is not necessary and may carry additional cardiac risk (FDA DCM investigation). High-quality grain-inclusive formulas from established brands like Purina Pro Plan and Hill’s are the vet-recommended choice.
