Hey there, I think RAW is great for your bullies. Are you wanting to switch for a particular reason e.g allergies or do you think it sounds a better diet for them?
I love RAW feeding and so does my bulldog Nelson who has been on raw fed since the age of 5 months and is doing well. The reason for my move from kibble was because he was allergic to everything and for me it was the only way to go to prevent him from a life on steroids. Raw feeding can sound complicated but its really not when you get into the routine of it, do your research obviously and read up her on the Raw feeding forum where you will get some great tips on how to start. The overall benefits of raw are general better overall heatlh resulting in less trips to the vets and longer life span, shiny coats, build immune system so helps against allergies and the dogs love it!! Better poops and less frequest and less smelly. If you are currently buying expensive kibble then you will probably find that you dont end up spending any more to move to RAW feeding, I can actually save money now as I was previously paying for a vet prescribed low grade kibble!!
Good luck, I dont think you have anything to lose by trying it!
