lab + dalmatian = only 1 pup?

[Cincy'sMom]

I really don't know what is normal, but my Sadie was the daughter of a Dal female (2 year old, first litter) and a male black lab. She was one of 11, 4 female, 7 males. Cincy was one of 8 from a black lab mixed female( age unknown, 2nd litter) and an unknown (hound?) male. Sorry I can't be of more help!
