Cairn Terrier chicken sensitivity in a multi-dog home

The tricky thing with multi-dog households is that one dog's dietary restriction can easily get blown by well-meaning partners or housemates grabbing a handful of treats for everyone — and chicken is in so many products people wouldn't even think to check. True food allergies in dogs are less common than intolerances, but either way the fix is the same: remove the trigger completely, which in a shared household means everyone needs to be on the same page. What breed and age is the dog with the sensitivity, what symptoms are you seeing, and have you had a vet confirm the chicken connection or worked it out through elimination yourself?

Three months of improvement is a really good sign — that's exactly how a dietary sensitivity should respond when you remove the offending protein. The itchy skin alongside loose stools is a classic dual-symptom presentation that strongly points to food rather than environmental triggers, so you're on the right track. The core problem you're describing isn't really Badger's diet, it's the treats being the weak link. What you need is a single treat that's genuinely chicken-free so your partner can grab one bag, give them to all three dogs without thinking, and Badger stays safe. Are the other two dogs any particular breed or size, and is there anything they definitely won't eat — any fussiness to work around?

Perfect — that mix actually makes this straightforward. You need something genuinely novel-protein, small enough for a Cairn Terrier, meaty enough for the Spaniel, and robust enough that the Lab won't inhale it and want twenty more. My recommendation is Lily's Kitchen Venison Sausages for Dogs. They're made with venison as the primary protein, completely free from chicken and poultry derivatives, and use simple ingredients without the fillers and by-products that often sneak chicken in through the back door. They're semi-moist, so they're soft enough for Badger's size, and the meaty smell tends to win over picky eaters like your Spaniel. Crucially, the ingredient list is short and honest, so your partner can check the bag once, feel confident, and use them for all three. One bag, one treat, no accidental chicken. I'd also suggest putting the bag somewhere visible in the kitchen so it becomes the default reach — that's usually what breaks the habit of grabbing whatever's nearest.

Venison is one of the most reliably safe novel proteins for chicken-sensitive dogs precisely because it's so rarely used in mainstream pet food — so most dogs simply haven't been exposed to it, and cross-reactivity between poultry and red game meat is not a recognised issue. The cross-reactivity concern is more relevant within protein families, like duck and chicken being both poultry. Venison, as a red deer meat, sits in a completely different category. Given Badger's already responded well to three months chicken-free, introducing venison as a treat should be straightforward. Just introduce any new treat gradually over a few days rather than a big handful on day one — more to avoid digestive upset from novelty than any allergy concern.

Definitely check the main food too — in fact that's always the bigger exposure. If Badger's been on a confirmed chicken-free complete food for three months and is doing well, you're probably already sorted on that front, but it's worth double-checking for anything labelled 'poultry' or 'poultry derivatives' rather than specifying the protein, because that can mean chicken without saying so. The treats are the issue right now because they're the variable that keeps changing. Get the treats locked down first with the Lily's Kitchen Venison Sausages, make sure everyone in the house is using the same bag, and if Badger has any further flare-ups after that, then go back and scrutinise the main food label closely. You've done the hard diagnostic work already — now it's just about closing the gaps.
