This is a specific conversation about Puppy food — getting the foundations right — ask about yours and get one honest answer for your exact situation.

Puppy nutrition is one of the most important investments you'll make — the right food in the first year sets the foundation for long-term health, and the differences between puppy foods are more significant than most people realise. A Cavapoo at 3 months is right in that critical growth window, so getting this sorted now really does matter. To point you in the right direction: what breed is the puppy, how old are they, and what are they currently eating?
She's a Cavapoo, just turned 3 months. The breeder gave me a small bag of something called Skinners but it's nearly run out. I've never owned a dog before so I genuinely have no idea what I'm doing with food.

That's really helpful, thank you — and honestly, the fact that you're asking now rather than just grabbing whatever's on offer at the supermarket puts you well ahead of most first-time owners. Cavapoos are a Cavalier King Charles Spaniel cross Poodle, so they're a small breed. That's actually important because small-breed puppies have faster metabolisms and different calorie and calcium needs than larger dogs. Skinners is a decent workhorse feed but it's not specifically designed for small-breed puppies. Can I ask — is she eating the Skinners well, any loose stools or anything like that? And is she roughly 3–5 kg at the moment?
She seems to be eating it fine, no obvious issues. She was weighed at the vet last week and she was 3.2 kg. They said she looks healthy.

Perfect — 3.2 kg at 3 months is exactly where you'd expect a Cavapoo to be. Right, here's my clear recommendation: Royal Canin Cavalier King Charles Spaniel Puppy dry food. I know it says Cavalier on the bag rather than Cavapoo, but because your girl is half Cavalier and Cavapoos are classified as a small breed, this food is genuinely ideal for her. Royal Canin formulate their breed-specific ranges around the real health tendencies of those dogs — Cavaliers are prone to heart issues as they age, so this formula has targeted nutrients to support cardiac health from early on. It also has the right kibble size and shape for a small jaw, supports her coat (Poodle crosses can have sensitive skin), and the protein-to-fat ratio is calibrated for small-breed puppy growth. Feed her three times a day at this age — the bag has a weight-based feeding guide on the back which makes it easy. When transitioning from the Skinners, mix them 75/25 in favour of Skinners for 2–3 days, then 50/50, then 25/75, then fully across. That prevents any stomach upset. It's available on Amazon UK in a 1.5 kg bag which is perfect for starting out — you'll want to see how she gets on before buying a larger bag.
That sounds really straightforward actually. How long does she stay on puppy food before I switch to adult?

For a small breed like a Cavapoo, switch at around 10–12 months. Small dogs reach their adult size much earlier than larger breeds, so you don't need to stay on puppy food as long as some people think. Royal Canin do an adult Cavalier formula too, so when the time comes you can transition her onto that and keep the same gradual switchover approach. One other thing worth knowing for right now: at 3 months she should still be on three meals a day. You can drop to two meals at around 6 months. Keep portions consistent and if she's leaving food, slightly reduce — Cavapoos can be a bit fussy and you don't want her learning she can hold out for something better.
This has been so helpful, thank you. I feel much more confident now.

You're going to do brilliantly — the fact that you're this thorough at 3 months in is a great sign. To recap: Royal Canin Cavalier King Charles Spaniel Puppy, transition over about a week from the Skinners, three meals a day until 6 months, then two. Switch to adult food at around 10–12 months. She's a lucky pup.
