Depends what you mean by sick. If you are diligent and consistent you can do it properly but unfortunately playing musical chairs with what is on sale is not diligence. Neither is not supplementing with a very high quality vitamin & mineral mix.
Bull.
I don't supplement with a "very high quality vitamin & mineral mix" and my dogs are fine.
I've asked before and you haven't answered, sable123 - what is YOUR experience with raw feeding?
Mine is over a decade of feeding raw to over a dozen dogs (young and old, healthy and sick) and 2 litter weaned to raw.
Tara - Do you want to feed an ALL raw food diet or are you just looking to supplement your current kibble?
If you are looking to feed an ALL raw diet you will have to include bones in the diet - EDIBLE bones. Very few of the bones you get from a butcher shop will be edible for your dog. You want things like chicken legs, necks, thighs, turkey necks, pork neck bone, etc.
As I said above, I have weaned puppies right to raw so 7 months old is NOT too early.
I'm not sure what you mean by "what is BEST for her digestive system"? Can you clarify?
The best meat to feed her daily depends on if you are going all raw or partial.
If you are going ALL raw you want to provide 3-5 different protein sources per week. Chicken, turkey, duck, pork, beef, lamb, fish, venison, rabbit, buffalo, etc.
If you only want to supplement your kibble then you can use anything you want - just be sure to cut back on the kibble on those days you give the raw meat.
Some of my dogs have been raw fed for over 10 years and have never been sick from it.
