Yes, i have been feeding 100% raw for 5 yrs now and have had no issues. Its great!!! but the only thing is the cost.... with 3 dogs it gets kind of expensive...
If u are concerned Apple seems hungry, maybe add some green beans to the raw. I heard green beans r suppose to make them feel full. Aside from the raw, i do give my dogs veggies a couple of time a week and of course their treats

. But even without veggies they dont seem to be hungry on just the raw..
Maybe try giving her more of the raw?? and see if that helps.. It takes some time to figure out the right portion for your dog but once u get a routine going, it will be great!!! Also, u will see a big difference in your dog!!!
Good Luck!
