Feeding a Pyrenean Mountain Dog (Great Pyrenees): common questions

How much should I feed a Pyrenean Mountain Dog (Great Pyrenees)?

A Pyrenean Mountain Dog (Great Pyrenees) typically weighs 38–60 kg, but the right daily amount depends on age, exact weight and activity — not the breed average. Start from the feeding guide on your chosen food (or our food portion calculator), weigh the portion rather than eyeballing it, and adjust to keep your dog lean enough that you can easily feel the ribs.

How many meals a day should a Pyrenean Mountain Dog (Great Pyrenees) have?

Split an adult Pyrenean Mountain Dog (Great Pyrenees)'s food into two meals a day rather than one large bowl — for a big, deep-chested breed this lowers the risk of bloat (GDV). Avoid vigorous exercise for 30–60 minutes either side of a meal.

Do Pyrenean Mountain Dog (Great Pyrenees)s need a special diet for their joints?

The biggest dietary lever for a joint-prone breed like the Pyrenean Mountain Dog (Great Pyrenees) is keeping them lean — every extra kilo multiplies the load on the hips and elbows. A complete food with added omega-3s (or a fish-oil top-up) supports the joints; ask your vet about glucosamine.
