Frequently Asked Questions
How much should I feed my Irish Water Spaniel?
Adult Irish Water Spaniels (45 - 68 lbs) should be fed according to the specific product's feeding guide. As a general guideline, divide the daily amount into two meals. Avoid free-feeding, as Irish Water Spaniels can overeat if food is always available.
Is grain-free food safe for Irish Water Spaniels?
The FDA investigated a potential link between grain-free diets high in legumes and dilated cardiomyopathy (DCM) in dogs. The research is ongoing and inconclusive. Unless your Irish Water Spaniel has a confirmed grain intolerance, a high-quality grain-inclusive food is generally recommended by most veterinarians.
