Hi labmad,
sorry about your boy. He could have become intolerant to the Burns ingredients even although he's been eating it for a while. Additionall, ear problems through allergy can take a significant time to develop and may be ongoing for months only becoming obvious when the dog starts to scratch or shake it's head a lot - this happened to one of mine, so, as I'm sure is the case for you, it's not neglect ;)
It could of course be the turkey roll but realistically it would depend on how much he'd eaten for it to cause a major flare.
Have you ruled out environmental allergens such as household cleaners, washing powder, air fresheners, furniture polish, hairspray, perfume, deodourant etc?
Re the runny tum - it may or may not be related to the ear problem. I'd fast him for 24 hours and then gradually re-introduce small portions of his usual diet (skip the rice/chicken stage unless there's signs of mucus etc).
For his ears (unless prescribed something already), clean out with some warmed almond oil, drip in, massage well at base and wipe with tissue until any residue is gone.
If your vet believes it is food related, has he suggested an exclusion trial?
regards, Teri :)
