Hi Emma,
I agree with Edith, wouldn't touch pedigree products with Edith's ten foot barge pole :shock: :shock:
Has he been wormed recently, just a thought. I think Burns is a very good dry food with no nasties in it, but I feed raw like Edith so can't really reccommend a good dry food other than Burns. My mum uses Burns venison and brown rice for her cocker and she loves it.
Naturediet is also a no nasty food but its moist and comes in a carton, its not dry food. I have seen a make called Gelert in Tescos which claims to be free of nasties but I've never tried it myself
Why not try Scoobs with some scrambled egg, that usually binds them up a bit when they're loose.
Good luck hope he recovers soon
Linda and Jess
