Weimaraner puppy soft stools — best food fix

Recurring soft stools that the vet has already cleared of infection — that's a really common landing spot with Weimaraners, and it almost always comes down to what's in the bowl. Weims have notoriously sensitive digestive systems, and at nine months they're still in a phase where the wrong protein source or too many additives can throw everything off. Before I point you toward something specific, can you tell me what food you're currently feeding — brand, flavour, and whether it's dry, wet, or a mix? Also, how long has this been going on, and has anything changed recently like a new bag from a different batch?

That's a really useful timeline — the fact it started at six months and has persisted points pretty clearly to a dietary sensitivity rather than a one-off upset. Royal Canin Maxi Puppy is a decent food in many ways, but it contains chicken, wheat, and maize, and any one of those three is a very common trigger for ongoing loose stools in Weimaraners specifically. The breed tends to do better on a single novel protein with no grains. Can I just check — has he ever had a food with salmon or fish as the main protein? And is he otherwise well in himself — good energy, normal weight, eating enthusiastically?

Perfect — that actually puts you in a great position. A novel protein he's never been exposed to means his immune system has no prior reaction to it, which is exactly what you want when you're trying to settle a sensitive gut. My recommendation is Barking Heads Puppy Days Salmon. It's a grain-free dry kibble with salmon as the single main protein, no chicken, no wheat, no maize. It's genuinely well-formulated for large breed puppies, and the fish oil content is a real bonus for Weimaraners — good for coat and joints as well as gut motility. A lot of owners with sensitive large breeds report firmer stools within two to three weeks of switching. The key is a slow transition — over ten to fourteen days rather than the usual seven — because his gut has been under stress and needs a gentle changeover. I'd swap about 25% at a time every three days or so. You'll find it on Amazon UK and it's usually well-stocked in the larger bag sizes which works out better value for a dog his size.

Just focus on the food change first — that's the main lever here. Adding a probiotic at the same time can be tempting, but it makes it harder to know what's actually working. Give the Barking Heads Salmon four weeks once he's fully transitioned, and if stools are consistently firm by then, you've found your answer. If they're better but not quite right, that's when it's worth adding a canine probiotic like YuMOVE Digestive Care to top things up. One change at a time keeps the picture clear. He sounds like a healthy, well-looked-after dog — this is almost certainly just a case of finding the right fuel for his particular system.

You're very welcome — good luck with it. Most Weimaraner owners who make this switch don't look back. Keep a note of how his stools look each week during the transition; it's genuinely useful information to have if you ever need to revisit things with your vet. He's lucky to have someone paying this much attention to getting it right.
