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.

A soy-intolerant dog sharing a home with a cat whose kibble contains soy — that's a genuinely tricky situation, because even small amounts of cross-contact at feeding time can keep your dog's symptoms ticking over. True food allergies in dogs are less common than intolerances, and soy intolerance is one of the more manageable ones once you've identified it — the main job now is eliminating every soy source, including the accidental ones. Before I suggest anything, can you tell me a bit more: what symptoms is your Airedale showing, how was the soy intolerance confirmed, and how are you currently managing mealtimes between the two of them?
He's 4 years old, been having loose stools and itchy paws for about six months. The vet did an elimination diet and we narrowed it down to soy. The cat eats James Wellbeloved dry kibble which has soy in it, and honestly I think Monty has been sneaking bits of it. We feed them in the same room and the cat often walks away leaving food in the bowl.

That's a really clear history — loose stools and itchy paws are classic soy intolerance signs, and you've done the hard diagnostic work already, which puts you well ahead. The sneaking from the cat's bowl is almost certainly the reason Monty's symptoms haven't fully resolved. Even a few bites of soy-containing kibble every couple of days is enough to keep the gut irritated and the paws scratching. So you actually have two things to fix: Monty's own food, and the opportunity for cross-feeding. What does Monty eat day-to-day at the moment?
He's on Harrington's adult dry food at the moment. I haven't checked whether that has soy in it to be honest.

Worth checking — Harrington's recipes vary and some do include soy or soy oil. But even if his own food is clean, the cat bowl issue will undermine everything unless you change that too. Here's what I'd do on both fronts. For Monty, I'd switch him to Canagan Grain Free Turkey for Dogs — it's a high-meat, grain-free dry food with no soy anywhere in the recipe, good quality protein for skin health, and it's widely trusted for dogs with food sensitivities. Airedales do well on higher-protein, lower-filler foods and at 4 he's in his prime, so it suits him well. For the cat situation, the simplest fix is separate rooms at mealtimes and picking up the cat's bowl the moment she walks away — don't leave it down. Longer term, it's worth considering whether you could move your cat onto a soy-free kibble too, which removes the risk entirely. But separating feeding immediately will make a real difference while you sort that.
That makes sense. Is Canagan easy to transition him onto, and how long before I'd expect to see improvement once the soy is fully out of his diet?

Transition over 7 to 10 days — start with about 25% new food mixed into his current food and increase gradually. Airedales can have sensitive stomachs so don't rush it. Once soy is completely out of his diet and the cat bowl raiding has stopped, you'd typically expect the loose stools to settle within 2 to 3 weeks. Skin and paw itching takes longer — allow 6 to 8 weeks for the inflammation to fully calm down. If you're not seeing meaningful improvement in the stools after 3 weeks with strict separation, it's worth going back to the vet to rule out a secondary issue, but in most cases removing the trigger source is all it takes.
Really helpful, thank you. I'll order the Canagan and start keeping them in separate rooms at mealtimes.

Good plan — that combination should sort it. Canagan Turkey is straightforward to find on Amazon UK. Keep a note of how quickly the stools improve once you've got clean separation, as that will tell you pretty quickly whether soy was the main culprit or whether there's anything else going on. Good luck with Monty — Airedales are tough dogs, he should bounce back quickly once the soy is out.
