Great advice already given, I'll add my two peneth. :)
Tom Lonsdale I find is the best author on a raw diet, his books are avaliable on Amazon/eBay. Ian Billinghurst is another option if you want to include veg/dairy/grains, but the books are a bit confusing at times I think. It is a very good idea to read up on the diet first, so as you have a good understanding of the diet before you take the plunge.
Personally I'd do a straight swap onto raw, I'm not a fan of mixing raw and dry with pups, but that's personal opinion. Start with one protien source (chicken probably being the best), try minces first and after a few days try bones (chicken wings are idea for toy breeds). After a week or so of that try adding another meat (rabbitt is good), and so on. Leave offal to last, and when trying her on liver and kidney remember TINY amounts to start with, they are very rich. DO NOT rush into trying too much variety, too soon. Big mistake, and will more than likely upset the pup.
If you want to do a gradual swap over, I'd feed raw in the AM and dry in the PM, and slowly cut down the dry and up the raw. If she is not keen on the raw try flash frying some mince to get her interested, then reduce how much you cook it until she is having it completly raw. Also, some comercially fed pups aren't keen on cold raw at first, so perhaps remove it from the fridge for a few hours prior to feeding would be a good idea.
She will need 10% of her ACTUAL body weight, or 3% of her EXPECTED body weight in raw. Calculate here.
http://www.raw4dogs.com/calculate.htmI prefer the 10% rule, as you can update this weekly. You can then tweek the amounts you feed going by if your pup gains/loses weight.
I use The Dog Food Company for food (
http://www.thedogfoodcompany.co.uk/products.html), but if you have a toy pup you may want to try one of the fully prepared raw diets such as natural instict (
http://www.naturalinstinct.com/), as it may not be too expensive with a small dog and the hard work is all done for you. Also, I'm sure they'd give you advise on what varietys to start on etc.
Having said all this, I would probably not change the pup to raw for a week or 2, just to let her settle in with you and find her feet.
Good luck. :)
