I've got 3 dogs on Orijen and haven't had any problems, they are all bundles of energy and because it's high in calorie you don't have to feed a lot.

I did find one of my dogs did have the runs for a few weeks after switching but after that he has been fine.

I also switched my grandad's Chihuahua onto Orijen, he had been on Bakers Complete with his previous owner. He had the WORST smelling sloppy poop for about 3 weeks, after 4-5 it became solid and he is doing really well on it, I think with some dogs it just takes longer for their digestive system to get used to it if it is vastly different to what they have been on before.

One brand I'd like to try now is the Applaws dry dog food which came out recently, it's also grain free with a high meat content. Has anyone got any yet, I think you can only get it from Mutley and Mog at the moment but Jollies Pet Store said they were considering stocking it also.
