This is a specific conversation about Dog food allergies — identifying and fixing them — ask about yours and get one honest answer for your exact situation.

A dairy-intolerant dog living with a housemate who gets regular yoghurt treats — that's a genuinely tricky setup, because even small accidental licks can keep the gut irritation ticking along. True food allergies in dogs are less common than intolerances, but dairy is one of the more frequent culprits for the latter, and Shelties can be particularly sensitive. Before I point you toward a solution, it helps to know the full picture: what symptoms is your Sheltie showing, and are they constant or do they flare up around the times the other dog gets their yoghurt treat?
She gets loose stools and occasional wind, mostly in the evenings which is exactly when we give our other dog, Barley, his yoghurt. She hasn't been tested by a vet but we're pretty sure dairy is the issue because it cleared up once when we forgot to buy yoghurt for a week.

That timing correlation is really telling — a week's natural elimination and the symptoms cleared is about as clear a signal as you'll get without formal testing. The evening pattern lines up almost perfectly with Barley's treat time, which suggests your Sheltie is either sneaking licks, cleaning the bowl, or just being in close enough contact to ingest small amounts. Has she been getting any of her own dairy-containing treats, or is her main diet already dairy-free?
Her main food is a fish-based kibble with no dairy listed, so that should be fine. The problem is definitely Barley's yoghurt. We don't want to take it away from him completely because his vet recommended it for his digestion, but we need something safer for her.

Good — if her main kibble is clean, the fix here is mostly about managing the shared-space treat situation rather than overhauling her whole diet. The key move is twofold: feed Barley his yoghurt in a completely separate room with the door shut, then give your Sheltie something equally rewarding at the same time so she's not stressed or left out. For her treat, I'd recommend Lily's Kitchen Soft & Tender Dog Treats — specifically the chicken or salmon varieties. They're completely dairy-free, made with whole ingredients, and soft enough that a Sheltie will find them genuinely exciting. Giving her one at the same moment Barley gets his yoghurt means she's not standing outside a closed door feeling left out — she's got her own thing. You could also use them as a training reinforcer if she has a habit of hovering around Barley's bowl.
That makes a lot of sense. Would it also be worth switching Barley to a dairy-free probiotic alternative so the yoghurt isn't even in the house?
inparticular.ai
Honestly, yes — that would be the cleanest solution if Barley's vet is open to it. There are good dairy-free probiotic supplements for dogs, like YuMOVE Digestive Care, that can do the same job as yoghurt without the dairy risk to your Sheltie. Worth mentioning to his vet at the next visit. But in the short term, the separate-room routine with Lily's Kitchen treats for your Sheltie should stop the symptoms pretty quickly — most dogs settle within a week once the trigger is genuinely removed.
Really helpful, thank you. I'll order the Lily's Kitchen treats and start the separate feeding routine tonight.

Perfect plan. Watch for improvement in her stools within five to seven days — if things haven't settled by two weeks of strict separation, it's worth a vet visit just to rule out anything else going on. But given the clear pattern you've described, I'd be surprised if it doesn't resolve quickly. Good luck to both of them.
