Finnish Spitz switching to cold-pressed kibble

Loose stools on day four of switching from wet pouches to cold-pressed kibble is actually a really common pattern — the gut hasn't had enough time to adjust, and cold-pressed kibble, despite being gentler than extruded food, is still a significant change in moisture content and digest rate. True food allergies are less common in dogs than food intolerances, but either way the most effective fix is usually a slow transition or an elimination diet using a novel or hydrolysed protein. Before I point you in the right direction, can you tell me a bit more? What's your Finnish Spitz's name and what were the wet food pouches — do you know the protein source in them? And are the stools just soft, or is there any mucus or blood?

Good — Siiri sounds fine in herself, which is reassuring. Forthglade chicken is a simple, fairly low-fat wet food, so moving straight to a cold-pressed kibble in one go is a bigger digestive shift than it looks. Cold-pressed kibble absorbs water in the stomach rather than before it, which can speed gut transit and cause exactly what you're describing. Which cold-pressed food did you switch her to, and how did you transition — gradual mix or a straight swap?

That explains it almost entirely. Two days is too fast for any dog, and wild boar is a novel protein for Siiri — her gut has never seen it, so it's processing something new at the same time as adjusting to a completely different food structure. The good news is this almost certainly isn't an allergy or intolerance — it's just a transition reaction. Here's what I'd do: drop back to about 75% her old Forthglade chicken mixed with 25% the Guru for another week, then move to 50/50, then 75% Guru, then full Guru. That usually resolves soft stools within a few days of stepping back. That said, if you want to stick with cold-pressed and make the transition easier, I'd actually suggest switching to Guru's Cold Pressed Duck rather than the Wild Boar — duck is closer in richness to chicken, it's still a novel protein if needed later for an elimination diet, and it tends to sit better with dogs new to cold-pressed. It's the same quality food, just a gentler entry point for Siiri's digestive system.

Exactly. Slow the transition right down — go back to mostly Forthglass for a few days, let her stools firm back up, then reintroduce the new food at no more than 25% increments every five to seven days. The Guru Cold Pressed Duck is available on Amazon UK and comes in a 5kg bag which is a good size to trial. If after a full slow transition on duck she's still getting loose stools, that's when it's worth speaking to a vet about whether there's a genuine intolerance — but I'd be surprised. Finnish Spitz are generally robust little dogs and Siiri sounds like she's just been asked to change too quickly.

You're welcome — Siiri's lucky to have someone paying close attention on day four rather than just pushing through. She should be back to normal stools within a few days of slowing down. If things don't improve after a proper slow transition, or if you ever see blood or mucus, that's the moment to call your vet. Good luck with her.
