Sorry Nicki but this is incorrect. Puppies are born 63 days after ovulation which is on average on day 10 of her heat. When the eggs are mature (usually 2 - 3 days after ovulation) they are fertilized. They can't be fertilized ten days apart as they are only viable for about 2 days after they mature. If there is sperm from two dogs present at maturation they can become pregnant by two different studs but all pups would be due at the same time. Small or undeveloped pups at birth are usually the result of poor placement in the uterine horn causing lack of resources. My info is from Canine Reproduction and Whelping, A Breeder's Guide by Myra Savant Harris and is an excellent resource.
I wouldn't breed her anymore after she bled just to be on the safe side, 2 - 3 ties are usually sufficient if the timing is correct.
