Frolic has anawful lot of Sugar as well as fat, as do all the foods with the plasic like soft chunks. As an odd treat they are OK but long term could cause you problems at least with the teeth. I would also avoid foods with unnecesary colurants (like Bakers) as they are there for the owners benefit (pretty shapes too) rather than the dogs.
Bitches certainly shouldn't loose theri coats in pregnancy, as the cyclical hair growth will all be in the growht phase, so she should have a super coat (expect a little loss around the nipples though). bitches will have a heavy moult, down to bare boards after the litter are weaned, but by then their coats are getting pretty tattered wh9ile nurding and raising the litter. In a heavy coated breed the hair loss can be quite shocking if you hadn't expected,a dn the bitch looks horendous just as new owners are picking up their pups, especuially if any have not gone by 8 to 12 weeks.
I did forget to say that meals should be split ifnot several a day as and when she wants them
