The Rough Collie is the "lassie" collie. gentle, devoted, brilliant family dog. Their nutritional needs reflect their 20–32 kg body weight, 12–14 years lifespan, and the breed-specific health considerations covered below.

Why feeding a Rough Collie is different

Because the Rough Collie is deep-chested, how you feed matters as much as what you feed. Gulped meals + immediate vigorous exercise are the classic GDV (bloat) triggers — slow feeders, two meals a day, and a 30–60 minute post-meal rest are the cheapest interventions you'll make.

With an active Rough Collie, calories go up — a working/sporting-line dog can need 30–50% more daily calories than a sedentary one of the same weight. Adjust for actual exercise, not the breed average.

The Rough Collie's coat needs omega-3 + omega-6 in roughly a 5:1 ratio for skin + coat condition. Fish-oil supplementation or a salmon-first food are the cheapest ways to get this right.

Below: a specific list of what to look for, what to avoid, plus our daily-calorie estimate for an average Rough Collie.

What to look for in food for a Rough Collie

A complete-and-balanced food labelled for dogs that meets FEDIAF or AAFCO nutritional standards.
Named animal protein as the first ingredient (e.g. "chicken", "salmon"), not "meat derivatives" or "animal by-product".
A working / sport formula with higher protein (28%+) and fat (15%+) for sustained energy.

What to avoid

Anything containing onion, garlic, raisins, xylitol or chocolate flavouring (common kitchen toxins for pets).

Feeding a Rough Collie: common questions

How much should I feed a Rough Collie?

A Rough Collie typically weighs 20–32 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 Rough Collie have?

Split an adult Rough Collie'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.

What should I look for in food for a Rough Collie?

Choose a complete-and-balanced food formulated for dogs that meets FEDIAF or AAFCO standards, with a named meat as the first ingredient rather than "meat derivatives", and match the life stage — puppy, adult or senior — to your Rough Collie's age.
