Although found on many different sites, it's pretty obviously a cut-and-paste job.Huge list of what's wrong with Bakers dog food including a list of 13 E-numbers and the fact that they have been banned in some countries as they are harmful.
Bakers is very popular and for sale in all supermarkets and pet shops.
I have checked some of the E-numbers and there are certainly concerns about some of them.
It is difficult to work out if it is founded in fact or if it's just a MacDonalds/Coke style hatchet job. I've not seen any refutation of the claims.
How is Joe Public (including me) supposed to know what to do? It has affected me - I have fed Bakers to my dogs in the past and don't any longer just in case and because it's easy not to - there are many similar products for sale.
