About 15 yrs ago before I'd heard about barfing, had an old red cattle dog that needed to lose some weight and vet suggested that we reduce her meal size by 1/2 and make up the bulk with grated raw carrot. Just this simple change alone apart from helping her lose weight, we saw some improvements in her coat, less incontinence probs, she was more active and showed more spark, less probs with grass seed allergies etc. Then found out about barf and decided to go the whole hog. Haven't looked back since. Rescue dogs that we fostered recovered from skin probs, improvements in arthritis w/o medication, found that old dogs are less likely to get that old dog smell...none of our dogs really get that doggy smell..they smell more like leather than the doggy pong you get on processed foods.
I basically give the raw meaty bones and then if I'm cooking vegies or using the other permissable barf ingredients in something I'm cooking for us, I keep a blender on the bench and throw the raw barf ingredients in that for the dogs as I go. So our dogs bascially get a selection of whatever we're having only raw. But its freshly prepared every day. I do however try to follow the following formula:
50%RMBs
10% organ meat
30% fruit and veg
10% other stuff eg raw egg, yoghurt, fish, cottage cheese etc.
I also add to the blender a bit of garlic and brewers yeast.
