This was an old post...
Tried CSJK9, no problems with it, just postage bumps up cost. There is also another company Eden pet foods who are competing at the top end / high meat content and british made. Also used applaws for a while, which seemed good but had a few runny stools which could have been dogs picking things up rather than product (they were also doing a buy two bags on special offer which brought price down).
Now feeding pedigree vital as recommended by dog trainer. Its not the quality I'd like but its cheap and easy to get (2 bags for £45, from a well known pet chain). Now having 2 collies instead of two wee westies, the rate of consumption is astronomical!
Burns ahs a good reputation but does have grains in it and I always surprised at how 'light' the kibble is - almost like rice crispies.
