Hi Jennin, depending on which pre-made raw you fed, that would be enough - I started out that way for a while but felt I could do it better myself so bought a dehydrator, mincing machine (forgot what you call minced meat over there).
Regardless of bought or home-made raw, I add in small quantities of garlic powder, Omega oil (the complex one), kelp liquid, vits/mins, spirulina, egg yolk occasionally, scrambled eggs occasionally, sardines, tuna etc. - probiotics & enzymes (if they get through Customs from USA).
In addition to their minced meat they also get bones to eat/digest daily (chicken wings, necks, carcasses), small ribs from veal or lamb etc. as well as recreational bones.
I dehyrdrate my own beef, chicken fillets, liver and kidneys which they absolutely adore. If you search BrodysMom's posts you find that a raw diet really is easy and cheap and consists of nothing more than raw meat, bones and secreting organs in 85%, 5% and 5% proportions respectively.
I only feed ZiwiPeak because it's 100% nutritional and convenient in that if I have to go away, an accident was to happen, I fell off my perch etc. my babies won't starve whilst someone gets the hang of feeding raw.
Apart from that, I simply couldn't entertain the thought of my Chi's eating "cooked" kibble or wet food, no matter how many stars it had - mine poop & pee a lot inside the home, sleep with me etc. and on a raw diet they are completely odorless (both poops & coats), tiny black, hard, inoffensive nuggets - my Mastiffs, who are outside dogs, on the other hand, unfortunately have to cope with cheap'ish' kibble (well, $55 for 18kgs or 40lbs) and weekly bones - they stink to high heaven, their poos are beyond massive, wretched & stinky and their teeth are not brilliant.
Remember, cooked kibble, no matter how good it is, sticks to dogs teeth like poop to a blanket, even if it has 5 stars & 10,000 glowing reviews!!!!
