This is a specific conversation about Dog gut health — probiotics and digestive support — ask about yours and get one honest answer for your exact situation.

Switching a dog from raw to kibble is one of the trickier dietary transitions — the gut microbiome is genuinely adapted to raw protein and fat, and kibble brings a very different enzyme demand, starch load, and bacterial profile. Probiotics can make a real difference here, but strain specificity and quality vary enormously, and what works for one dog may do nothing for another. Before I point you anywhere specific: what breed and age is your dog, what symptoms are you already seeing or trying to prevent, and have you had a chance to speak to a vet about the switch?
He's a 3-year-old Siberian Husky called Kodak. We're moving him from raw to kibble mainly because of cost and convenience — no symptoms yet but I know Huskies can have sensitive stomachs and I want to get ahead of any loose stools or vomiting during the changeover. We haven't spoken to a vet about it, it's just a diet change.

Good that you're thinking ahead — Huskies do tend toward digestive sensitivity, and the raw-to-kibble switch specifically puts a lot of pressure on the gut because the microbial population has to shift quite significantly. The main risks in the first two to three weeks are loose stools, excess gas, and occasional vomiting as his system adjusts to the increased carbohydrate content and different protein sources. Can I ask: are you planning a gradual crossover — mixing raw and kibble for a week or two — or going more directly across? And do you know yet which kibble you're moving him to?
I was planning to do a gradual crossover, about ten days mixing them slowly. I'm going to use Orijen Adult dry food because it's high protein and close to what he's used to on raw. I just want something to support his gut through that ten-day period and maybe a bit beyond.

Orijen is a sensible choice for this — the protein profile is close enough to raw that the jump isn't as dramatic as switching to a standard supermarket kibble. For the probiotic support, the product I'd point you to is Purina Pro Plan FortiFlora for Dogs. It's a sachet-based supplement — one sachet per day sprinkled over food — containing the strain Enterococcus faecium SF68, which has more published clinical evidence behind it than almost anything else on the market for canine digestive transitions. It's also highly palatable, which matters because some dogs go off their food slightly during a diet switch and you don't want a supplement that makes that worse. For Kodak, I'd use it daily throughout the ten-day crossover and for about a week after he's fully on the kibble — so roughly seventeen to twenty days total. It's available in boxes of thirty sachets on Amazon UK, which gives you plenty of buffer. One thing worth noting: FortiFlora contains a small amount of animal digest for palatability, which is fine, but it's worth knowing it's not a 'clean label' supplement if that matters to you.
That sounds really practical. Is there anything else I should be doing during the transition beyond the probiotic?
inparticular.ai
Yes — a few practical things make a real difference. Keep the crossover slow even if he seems fine: days one to three at roughly 25% kibble, days four to six at 50%, days seven to nine at 75%, then fully across by day ten. Don't rush it if you see loose stools — just hold at that ratio for an extra day or two. Adding a small amount of plain canned pumpkin (not pie filling, just plain pumpkin) can help firm stools during the wobblier days — about a tablespoon per meal for a Husky his size. Make sure he's drinking well because kibble carries far less moisture than raw and dehydration can compound digestive upset. And if you see blood in the stool, persistent vomiting, or he goes off food for more than a day, that's a vet call — not a 'wait and see.' Huskies are generally robust once they're through the transition, and with Orijen plus FortiFlora you're giving Kodak a genuinely good setup.
Really helpful, thank you. I'll order the FortiFlora today and start the crossover this weekend.

Perfect timing — starting on a weekend when you can keep an eye on him is exactly right. Good luck to Kodak with the switch; most dogs settle in well once the microbiome catches up, usually by the end of week three. If anything unexpected comes up during the transition, worth a quick call to your vet just to be safe.
