Our 18 month old labrador, Zico, has been on JWB topped up with quarter a pack of naturediet for around 6months now with no problems, however over the past few weeks he has been letting off toxic fumes. Really awful smelling. His number 2's are sometimes firm, sometimes ever so slightly loose. Any advice on what to do? Should I try him on a different food? Seems odd that it's just been recently and seems perfectly fine otherwise. I was looking at Arden Grange last night online, and there is a wee shop not far from me, who also deliver, and on the plus side it seems a wee bit cheaper than the arden grange website.Dog Food from Just Dogs Just Dogs Any help would be much appreciated.
