Well first off, welcome to the forum, and congrats on the new addition! I can't wait to see puctures of your pur babies. *hint, hint* lol.
And good for you on wanting to go raw. It's probably the very best decision you'll ever make for your dogs. The results are amazing, you will not regret it!
I really want to switch over to raw but other than chicken quarters I don't know what to feed them.
Just about any kind of raw meat you can think of is okay.
You just don't want to give oddly cut bones. I try not to feed any cuts smaller than my dog's mouth, jsut as a rule of thumb. Things I buy regularly:
Chicken Leg Quarters
Whole Turkey
Turkey Necks
Pork Shoulder Pcnic Roast
Lamb Breast
Beef Ribs
Beef Brisket
Boneless Beef Shank
Goat
Beef Kidney
Pork Heart
Chicken Liver
Whole Talapia
Whole Sardines
Canned fish
I don't know if I can give the puppy a chicken quarter at 4.5 months or is she too young to chew that bone up?
My cocker spaniel started chicken leg quarters the night we brought her home at 12 weeks old. Chicken bones are some of the easiest for them to chew and digest, so they are a perfect starting point, and your pup can definately handle them.
I also am not sure how much to feed the 15 month old, Mack. He is about 105 pounds right now, a little light compared to his dad and mom who where 135 and 120.
Feed 2-3% of his ideal ADULT body weight, not current weight. Then over time yu can adjust that amount based on body condition, but that gives you a starting point.
I really hope this helps,feel free to ask any more questions you might have. Raw can be intimidating at first, but once you get in the swing of things, you'll see just hoe easy it really is!
