An Irish Wolfhound puppy at 10 weeks — you're already thinking about this the right way. Giant breeds like Wolfhounds are genuinely different from other dogs when it comes to food. Their growth plates stay open for a long time, and pushing them to grow too fast is one of the leading causes of joint problems down the line. How much does your pup weigh right now, and what are you currently feeding them?
He's about 8kg already. We've been using the food the breeder gave us but it's a general puppy kibble, nothing breed-specific. I've heard giant breeds need lower calcium — is that true?
inparticular.ai
Partly true, but it's more nuanced than that. It's not just about calcium being low — it's about the calcium-to-phosphorus ratio being correct, and critically, the energy density not being so high that he packs on weight faster than his skeleton can handle. A general puppy food is often too calorie-dense and has the wrong mineral balance for a dog that's going to reach 70kg or more. What matters is controlled, steady growth — not fast growth. Has the breeder given you any specific guidance on feeding amounts or brands?
They just said avoid puppy foods marketed for small or medium breeds and don't overfeed. That's about it. I want something I can trust rather than piecing it together myself.

That's sensible advice from the breeder, as far as it goes. For a 10-week Wolfhound, I'd point you to Royal Canin Giant Puppy. It's specifically formulated for breeds that will exceed 45kg as adults — exactly your situation. The calcium and phosphorus levels are calibrated to support bone development without accelerating growth, and the energy content is moderate enough that you're feeding the skeleton, not racing it. It's also easy to find on Amazon UK in large bags, which matters because you're going to be getting through a fair amount of it. He should stay on a giant-breed puppy formula until around 18 to 24 months, not 12 like a smaller dog.
That makes sense. Is Royal Canin Giant Puppy different from their Maxi Puppy? I've seen both and wasn't sure which applied to him.
inparticular.ai
Yes, and it matters. Maxi Puppy is for dogs with an adult weight of roughly 26 to 44kg. Giant Puppy is for dogs expected to exceed 45kg as adults — which an Irish Wolfhound absolutely will. The Giant formula has a lower energy density and a more carefully controlled mineral profile to account for that much longer growth period. Always go Giant, not Maxi, for a Wolfhound. The kibble size is also larger, which suits a big puppy jaw even at this age.
Perfect, that's exactly the clarity I needed. I'll order the Giant Puppy. Anything else I should watch for while he's growing?
inparticular.ai
Two things. First, keep him lean — you should be able to feel his ribs without pressing hard. Wolfhound owners sometimes confuse a puppy looking 'well-fed' with him being healthy, but extra weight on developing joints is genuinely damaging at this stage. Second, hold off on long walks or hard exercise until he's much older — 18 months minimum for anything strenuous. Short, free play sessions in the garden are fine, but forced roadwork or repetitive jumping isn't. You're already ahead of most people by asking this question at 10 weeks.
