there are alot of views on this and ive heard dont mix them as they digest differently and ive had many people tell me they mix their kibble with raw and they have no problems. ive also heard to leave 12 hours in between so an am of raw and pm of kibble should be ok. salmon oil is good for shedding and the coat i use 2 pumps and sarah is 47 pounds. however i would not be adding all these things all at once to your dogs diet. i would add one at a time and then see how things go. lots of bullies are allergic to salmon and such so be slow when adding things.
