Dog food for sensitive stomachs

Three sensitive stomach foods and still vomiting — that's genuinely exhausting, and it usually means the issue isn't just sensitivity but something more specific being triggered. Sensitive stomach problems in dogs tend to fall into a few categories: food intolerance, a reaction to a particular ingredient that keeps appearing across products, or a gut that needs a much simpler, more digestible diet than most commercial foods provide. Working out which of those is driving this is the key. Can you tell me what the three foods were, and what ingredients they had in common? And is the vomiting happening shortly after eating, or a few hours later?

That timing — within an hour — points strongly toward a food intolerance rather than a slow digestive issue. The interesting thing about those three foods is that they all contain either chicken fat, oats, or both, even when the primary protein looks different. Purina Pro Plan Sensitive uses salmon but includes chicken fat; James Wellbeloved Turkey contains oats; Forthglade also uses oats in most recipes. Has he ever had a food that didn't cause vomiting, even briefly? And is the vomiting bile-coloured or does it look like undigested food?

The fact that he thrived on raw is really useful — it tells you his gut handles single-protein, grain-free food well. The oats connection is worth taking seriously. Many so-called sensitive stomach foods use grains as a gentle filler, but for some dogs they're actually the problem. Whippets also have lean, fast digestive tracts, which means anything slightly irritating moves through quickly and often comes back up. I'd suggest moving to a food with a novel single protein, no grains at all, and a very short ingredient list. My recommendation is Lily's Kitchen Grain-Free Chicken and Turkey. It's a dry kibble with a genuine short ingredient list — chicken and turkey as the only proteins, no oats, no wheat, no rice. It's not raw, but it's probably the closest commercially available option to what his gut already knows how to handle. Transition slowly over ten days even if he seems fine, and keep a note of any reaction in the first week.

Lily's Kitchen does make wet food too — their grain-free tray range uses similarly clean ingredients and would be worth trying if the kibble causes issues. On your second question: the pattern here — vomiting undigested food consistently across multiple foods, but doing well on a simpler diet — is more consistent with food intolerance than with something like IBD or a structural problem. Those tend to cause more persistent symptoms regardless of diet changes, and often involve weight loss or lethargy, which you haven't mentioned. That said, if Lily's Kitchen doesn't settle things within three to four weeks, a vet visit with a full dietary history is the right next step. At that point they might suggest a hydrolysed protein diet or proper elimination trial. But I'd give this a fair run first — it fits his history well.

Good plan. Ten-day transition, one change at a time, and watch specifically for any vomiting in that first hour window — if that clears up you'll know you've likely found the culprit. Hope it's the last food switch he needs.
