Dog food after blood in stool: Keeshond guide

Blood in the stool — twice, on foods specifically marketed for sensitive stomachs — is genuinely alarming, and I completely understand why you're being cautious now. That pattern suggests your dog isn't just dealing with a mildly reactive gut; something in those formulas is actively irritating the digestive lining. Sensitive stomach issues in dogs usually fall into a few categories: food intolerance to a specific protein or additive, a broader ingredient sensitivity, or a gut that simply needs a much plainer diet to settle. Working out which applies here is the key to finding the right food. Can you tell me: what breed and age is your dog, exactly what symptoms you're seeing beyond the blood, and which foods you've already tried?

That's a really useful pattern — bright red blood appearing consistently around the two-week mark, not immediately, tells me this is likely a delayed irritation response rather than a one-off upset. Both Royal Canin Sensitive and Pro Plan Sensitive share some common denominators: poultry-based proteins, rice, and various additives including preservatives and flavour enhancers. Keeshonds can have particularly reactive guts, and two-week-delayed bleeding points strongly toward a protein or additive intolerance building up over time. Before I suggest something, what protein is in the food he's currently stable on? I want to know what his gut tolerates even if it's not ideal.

Okay — so he tolerates chicken reasonably, but wheat and whatever additives are in that supermarket food are keeping his gut unsettled. The two problem foods were both chicken-based with rice and a longer ingredients list. My suspicion is that it's not the chicken itself causing the bleeding, but rather a combination of additives, specific binders, or the way those foods are processed — both Royal Canin and Pro Plan Sensitive use quite a few additives that cheaper wet or natural foods skip entirely. I'd move him toward Forthglade Complete Adult Grain Free — specifically the chicken with liver and vegetables variety. It's a wet food, very short ingredient list, no grains, no artificial additives, and it's a gentle single-protein format. The soft texture is also much easier on an inflamed gut than dry kibble. Start by mixing it in over ten days rather than two, go slowly, and watch closely. If he gets to four weeks with no blood and firmer stools, you've found your food.

That's a common assumption but it's not really backed up by evidence. Wet food is perfectly complete and appropriate as a long-term diet as long as it's labelled as complete rather than complementary — Forthglade Complete is, so that's covered. The higher moisture content in wet food actually tends to support gut health because it keeps digestion moving more smoothly. The one practical thing to watch is dental hygiene, since wet food doesn't provide the mechanical scrubbing that dry kibble does — but a dental chew a few times a week handles that easily. For a dog with his history, the benefits of a simpler, additive-free wet food well outweigh the minor extra effort.

Give it a full four weeks before you make any judgement. In the first week or two you might see things get slightly worse as his gut adjusts — that's normal. By week three, if this is the right food for him, you should start seeing firmer, more consistent stools and less gas. If you reach four weeks with no blood and noticeably better stools, that's your answer. If blood appears again at any point, stop immediately and go back to his current stable food, and at that point it would be worth a vet visit to rule out anything structural going on — two recurrences on different foods means this absolutely warrants investigation if it happens a third time.
