Thanks for your replies, they are really helpful. The website you told me about Rachel is very informative and I think I will be referring to it a lot.
Lisa, you have told me really what I needed to hear and that there are no hard and fast rules about Barf feeding. I have found out since yesterday that Ronald can't cope with the chicken wings - he finds it difficult to poo, the others are doing fine and the cat loves them. I did read on COL that they needn't have a balanced meal everytime but as long as they have a balanced diet over time so I will bear that in mind and introduce different foods slowly. They've not had veg yet but will be introducing this now, and then a bit of pasta. Do you feed the dry pasta raw? or buy fresh. Also how do most barfers prepare their veg. I have got sweet potatoes, toms, broccoli and parsnips for them - are any veg forbidden foods for dogs?
One other thing, what percentage of meat to veg and pasta do you use. I can then use this as a guide to start off with and change their diets accordingly.
Sorry if all of this has been answered before, any help is greatly appreciated
