RAW FEEDERS-Allowing dog to drink the blood from meat packages-yay or nay? And how much fat?

I just got a 15 lb shipment of lamb from a place called Green Zabiha. Each lb is shrink wrapped and each contains a couple tbs of blood at the bottom. I'll be going through a little over 2 packages per week between her and my two cats (it's all for them) and accounting for the bone (none of them will eat it so I'm making them lamb broth) I know you aren't normally supposed to give them the blood because of salt, etc. but this is organic, gr fed, additive free meat and it seems a good source of vitamins, especially while I'm waiting for the next bag of liver. I would only be giving her the juices of one package per week because she'd be sharing with the kitties as well. Also, how much fat should I give her? She's been eating 2 oz a day of 15% fat ground beef (only organic grfed meat I can get around here) plus small amounts of dehydrated chicken organs and a couple tbs of steamed purred veggies, and of course her supplements, including about half a tsp of salmon oil. Her weight is perfect at 7.4 lbs, energy is sky high and she's nicely muscled so I think she's getting the perfect amount
