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.

Bloody stools in a 7-month-old puppy is something you need to take seriously — and chicken is actually one of the most common dietary triggers in dogs. True food allergies are less common than intolerances, but both can cause gut inflammation severe enough to produce blood, and the most reliable way to identify the culprit is an elimination diet using a novel or hydrolysed protein your pup has never eaten before. To point you in the right direction: has your Malinois been seen by a vet about the blood, and how long has this been going on — days or weeks?
He's been on the chicken food since we got him at 8 weeks. The bloody stools started maybe three weeks ago. We did go to the vet — they ruled out parasites and infection and said it's likely a food sensitivity. They told us to try a different protein but didn't recommend anything specific.

Good — ruling out parasites and infection first is exactly the right step, so now you can focus on the food. Three weeks of bloody stools on a chicken-based diet points pretty clearly at the chicken or possibly the grains in the formula. For an elimination diet to work properly, you need a food with a single novel protein source he's genuinely never had, no chicken, no beef, no common fillers. What else has he eaten since you brought him home — any treats, chews, or table scraps beyond his main food?
Mostly just the puppy kibble. We've given him a few chicken-flavoured treats from the pet shop, and occasionally a bit of plain cooked chicken as a reward. Nothing else really.

That actually makes the picture clearer — chicken has been his only significant protein exposure, which means switching away from it gives you a clean trial. For a 7-month-old Malinois, you also need a food that supports a large, active breed puppy properly during this growth phase, so you don't want to compromise on nutrition just to do the elimination. My recommendation is Canagan Grain Free Turkey for Puppies. It uses turkey as a single named protein, no chicken, no grains, and it's nutritionally complete for growing dogs. Canagan sources well and the ingredient list is clean. Switch over 7–10 days by mixing increasing amounts of the new food with decreasing amounts of the old. Critically, stop all chicken treats for the full 8-week trial — even a small amount can invalidate the result.
That sounds straightforward. How quickly should we expect to see an improvement if it is the chicken causing this?

Most dogs show meaningful gut improvement within 2–4 weeks of removing the offending protein, but the full elimination trial should run 8 weeks before you draw conclusions. With bloody stools specifically, you should see the bleeding ease within the first two to three weeks if chicken is the problem. If the stools are still bloody after four weeks on the turkey food with zero chicken exposure, go back to your vet — at that point there may be an underlying gut issue like inflammatory bowel disease worth investigating. Keep a simple daily log of stool consistency and any blood; it'll help enormously if you need to report back.
Really helpful, thank you. We'll order the Canagan Turkey and ditch the chicken treats straightaway.

That's the right move. One last thing — once the 8 weeks are up and stools are normal, you can do a controlled reintroduction of chicken if you want to confirm it's the culprit, but honestly many owners just leave well enough alone once they find something that works. Good luck with him — Malinois are high-drive dogs and the last thing you need is a gut problem slowing him down.
