Fish-based food causing serious flatulence is a pretty clear sign that protein isn't agreeing with your dog — it's one of the more common reactions, actually, and worth taking seriously rather than pushing through. Choosing the right food genuinely depends on the individual dog: age, size, breed, and health history all pull in different directions, and the most marketed options are rarely the best fit. Before I point you anywhere, it helps to know a bit more — what breed and age is your dog, are there any other health issues or sensitivities you're aware of, and what were you feeding before the fish food?
She's a 9-year-old Miniature Dachshund. The fish food was a wet food I tried switching to because she was getting bored of her old kibble. No other known health issues, but she does have the typical Dachshund back concerns — we're careful about her weight. She was on a standard chicken kibble before.

That's really helpful, thank you. A few things stand out here: at 9 she's a senior dog, so joint and weight support matter more than they used to. Dachshund backs are a genuine concern — keeping her lean is one of the best things you can do for her spine, so calorie density is worth watching. The fish intolerance is notable; some dogs just can't handle oily fish proteins without a lot of gut upset. Given she was fine on chicken before, returning to poultry makes sense — but I'd lean toward a single-protein, clearly labelled food rather than a generic supermarket mix. Is she eating well in general, good energy, normal stools otherwise?
Yes, she's got good energy for her age, eats well, and her stools are normal when she's on the right food. She just really suffered with the fish — it was pretty bad for about two weeks before I stopped it.

Good — that confirms the issue was the protein source rather than anything systemic. Two weeks of that kind of reaction is rough on both of you. For a 9-year-old Mini Dachshund where weight management and a clean, identifiable protein are the priorities, I'd point you to Forthglade Complete Meal Grain Free Turkey with Sweet Potato & Vegetables in the senior wet food format. It uses turkey as the single named meat protein — straightforward, easy to digest, and much lower in fermentable oils than fish. It's grain-free, which tends to suit smaller breeds well, and the sweet potato gives slow-release carbohydrate without spiking calories. The senior formula is calibrated for dogs over 7, so the nutritional profile fits her stage of life. Portion control is easy with wet food too, which helps if you're monitoring her weight closely. It's available on Amazon UK and widely stocked — you can start with a multipack to trial it before committing.
That sounds really sensible. Should I do a gradual transition from the old food, or since the fish one caused problems should I just switch straight over?

Since the fish food is already stopped and she's had a two-week break from it, you can transition from whatever she's on now — even if that's back to the old chicken kibble as a bridge — over about a week. Start with roughly 25% Forthglade and 75% old food for a couple of days, then 50/50, then 75/25, then fully across. Her gut has already had a disruption so keeping the transition gradual gives it time to settle. If stools stay firm and no gas appears, you're in good shape. She should do well on it.
