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. |
