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

Artificial colours in pet food causing behaviour changes is more common than people realise — and it's really good that you've spotted the connection rather than just putting it down to the puppy being lively. 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 far more significant than most people expect. To point you in exactly the right direction: what breed is your puppy, how old are they, and what food were they on when you noticed the hyperactivity?
She's a Lhasa Apso, just turned 8 months. She was on Bakers Complete puppy and she was bouncing off the walls — I did some reading and think the artificial colours were the problem. She's small, around 4kg at the moment.

Bakers is actually quite well known for this — it contains several artificial colours including Red 40 and Yellow 5, and there's a real body of evidence linking synthetic dyes to hyperactivity in sensitive dogs, particularly smaller breeds. Lhasa Apsos can also be prone to skin and digestive sensitivity, so getting her off the artificial stuff at 8 months is genuinely good timing. Before I give you my recommendation, is she eating wet food, dry, or a mix? And have you noticed anything else — any loose stools, itchy skin, or is it purely the behaviour?
Just dry food. No skin issues that I've noticed, mostly just the hyperactivity and she did seem to have slightly loose stools on it too. I'd like to stick with dry if possible.

The loose stools alongside the hyperactivity does point strongly to the artificial additives — Bakers has a high cereal content too, which can upset digestion in smaller dogs. For a Lhasa Apso at 8 months who's reacted to artificial colours, I'd go with Lily's Kitchen Puppy Recipe dry food. It's completely free from artificial colours, flavours, and preservatives — everything in it is natural and clearly listed. The protein source is freshly prepared chicken and turkey, it has good botanical herbs and botanicals for gut health, and the kibble size is well suited to smaller breeds. It's also grain-inclusive but uses wholesome grains like oats rather than cheap fillers, which tends to be much easier on digestion than what she's been on. You should notice a difference in her behaviour and stools within about two weeks of switching — just transition gradually over 7 to 10 days to avoid any upset from the change itself.
That sounds exactly what I'm after. How do I transition her onto it without causing more tummy upset?

Really straightforward — start with around 25% Lily's Kitchen mixed with 75% of the old food on days one and two, then go 50/50 for a couple of days, then 75% new and 25% old, and by day seven to ten she should be fully on the new food. If at any point her stools go loose again, just slow the transition down rather than pushing through. At 4kg she'll only need a small daily portion — roughly 65 to 75 grams per day split across two meals, though the pack has a guide. The fact that she's 8 months means she's got a few more months left of puppy-specific nutrition, so stick with a puppy formula until she's around 12 months.
Perfect, thank you. I'll order some today.

Great choice — you're doing exactly the right thing catching this at 8 months. Lily's Kitchen is widely available on Amazon UK in various bag sizes; the 1kg or 2.5kg bags are a good starting point before you commit to a larger quantity, just to make sure she takes to it well. I'd expect you to see a calmer, more settled pup within a couple of weeks. Good luck with her!
