I added green beans as a filler with a dog who needed to watch her weight but had a large appetite. Only 25 calories for 1/2 cup.
Most commercial turkeys are injected with a salt/other chemical solution - not necessarily what I want to feed my pets. Fresh ones aren't, but they are pricey.
Ginger, what is the Aussie being fed instead of bone? Raw should consist of 80% muscle meat, 10% bone and 10% organ meats, with only of that half liver. My last two dogs were raw fed - it was fun sourcing organ meats other than liver. There's some ugly stuff out there.
My cats are supposed to be on either wet or raw food, but they are kibble addicts and it's not going well.
