Your bitch needs to drink lots, and you should not be giving bone as calcium supplements are the ones along with VitD most likely to cause problems.
With cleaning that many puppies her mouth will get sore, and this is the reason I soak the food to a slop.
I don't think most people would consider Wagg a 'quality' food, but if your dogs do well on it? There are far superior foods at similar prices.

With only a guarantee of 10% meat (the better proteins for body building, your growing puppies very quickly) in the food as compared to at least 40% in some of the better puppy foods. Also with only 10% fat it will be rather low in energy, needed for the bitch to make milk.
