Are you giving her a calcium supplement. She will definitely need one. I recommend Pet-cal or Doc Roy's Healthy Bones from Revival. I give my females 1/2 tablet in the morning and one 1/2 in the evening. It is also essential that the momma eats about 4 meals a day, the last meal being right before bedtime.
I am not familiar with Origen dog food so I can't comment on it. I always give my mommas dry Chicken Soup puppy food mixed with canned Pedigree puppy food.
Be sure you have Oral Cal Plus on hand just in case the momma has any problems with eclampsia. You can get it from Revival also.
BTW, congratulations on your new litter.
