Luna is now heading into her last week of pregnancy too. Though Zoe was mated 5 days before Luna I think the pups will arrive closer together. Zoe ovulated on the Tuesday and was mated Wednesday, Luna ovulated 2 days later on the Friday, but wasn't mated till Monday. Going on ovulation dates the pups could come as soon 2 -3 days apart. When people have used my dog I like to show interest and be helpful where I can, to be honest I'm really excited.
