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.

Bloating and gas after every single meal, right from weaning — that's a pretty telling pattern in a young Rottweiler, and it almost certainly points to a food intolerance rather than a true allergy. True allergies are actually less common than most people think; what you're describing sounds more like the puppy's gut struggling with a specific ingredient, most likely a protein source or a fermentable carbohydrate. The most reliable fix is usually an elimination diet using a novel or hydrolysed protein — something the dog has never been exposed to before. To point you in the right direction: what are you currently feeding him, and is the bloating mostly visible distension, a lot of wind, or both?
He's on a standard supermarket puppy kibble — I think it's chicken and rice. The bloating is both really, his belly looks puffy after meals and he's really gassy. He's 6 months old and about 28kg already. Haven't seen a vet yet, thought I'd try changing the food first.

Good instinct to start with food, though I'd say get a vet check booked too — Rottweilers are a deep-chested breed and genuine GDV (bloat that twists the stomach) is a serious risk in the breed, so it's worth ruling that out. That said, what you're describing — consistent gas and puffiness after every meal since weaning, on a chicken-and-rice kibble — reads strongly as a chicken intolerance. Chicken is one of the most common intolerances in dogs precisely because it's in almost everything they eat from birth. Has he ever had any food that wasn't chicken-based?
No, it's been chicken from the start. Everything we've tried has had chicken in it. So should I be looking at a completely different protein?
inparticular.ai
Exactly right — you want a single novel protein he's never had, with no chicken, no chicken fat, no poultry derivatives anywhere on the label. For a 6-month Rottweiler puppy this size, I'd go with Purina Pro Plan Sensitive Skin and Stomach Puppy with Salmon. It's a single animal protein formula, properly balanced for large-breed puppy development which matters a lot at this age and size, and salmon is genuinely well-tolerated by dogs that react to poultry. It's also relatively low in fermentable fibres that can drive gas. Feed it exclusively for 6–8 weeks — no treats, no chews, nothing with chicken — and you should see a clear difference in the bloating and wind within the first two to three weeks if chicken is the culprit.
That makes sense. Should I be doing anything else differently — like how I feed him? He tends to eat really fast.
inparticular.ai
Yes, absolutely — speed eating is a major contributor to gas and bloating in deep-chested dogs, and in Rottweilers it's genuinely worth taking seriously given their GDV risk. Split his daily portion into three smaller meals instead of two, and use a slow-feeder bowl to force him to eat more slowly. Avoid any exercise for at least an hour before and after meals. Those changes alongside the food switch should make a significant difference. If the bloating doesn't improve within three weeks on the new food, or if you ever see hard, tight, painful distension — especially with unproductive retching — go to the vet immediately, don't wait.
Got it. So Purina Pro Plan Sensitive Salmon puppy, split into three meals, slow feeder bowl, and book a vet check anyway. Thanks, that's really clear.

That's exactly it. The vet visit is just sensible belt-and-braces with this breed — they'll likely agree the food change is the right call too. Give the elimination period the full 6–8 weeks before you judge it, and resist the urge to introduce anything new during that window. Fingers crossed you see improvement quickly — gas and bloating that started at weaning and ties directly to chicken is usually very responsive once you remove the trigger.
