Best food for French Bulldog digestion issues

So your vet has flagged the food as the likely culprit for your Frenchie's digestion issues — that's actually one of the more useful things a vet can tell you, because it gives you something concrete to act on. Supermarket brands often rely on cheap fillers and vague meat derivatives that sensitive dogs like French Bulldogs can really struggle with. Before I point you somewhere specific: does your dog have loose stools, lots of wind, or both? And do you know if the current food is chicken-based or something else?

That tracks. Frenchies are notorious for digestive sensitivity, and a lot of them don't actually do well on chicken — it's one of the more common triggers for gut irritation in the breed. Combined with the lower-quality ingredients in supermarket kibbles, you've probably got a double problem. Is he on any medication, or just the food change your vet is recommending?

Good — straightforward case then. My recommendation is Lily's Kitchen Adult Dry Dog Food with Chicken and Duck. I know you mentioned chicken might be an issue, but Lily's Kitchen uses named, high-quality meat rather than derivatives, and the duck in the recipe changes the protein profile enough that many chicken-sensitive dogs tolerate it well. More importantly for Frenchies, it's free from wheat, maize, and soy — the big three digestive irritants — and it uses natural prebiotics to actively support gut health. It's meaningfully better than anything supermarket-tier and it's specifically formulated to be gentle on digestion. If after a couple of weeks you're still seeing issues, that would be the point to consider a fully novel protein like duck-only or salmon.

Slowly is the key word. Over about ten days, mix increasing amounts of the new food into the old: start at roughly 25% new, 75% old for the first three days, then 50/50 for the next three, then 75% new for a few days, then fully switched. It feels slow but it gives the gut bacteria time to adjust. If you go too fast you'll get loose stools regardless of how good the new food is, and you won't know whether it's the transition or the food itself.

Good choice. Give it a full four weeks before you judge it — digestion changes can take time to fully settle. If the wind improves but stools are still loose after that, come back and we can look at whether a single-protein food makes sense next. You're on the right track.
