[QUOTE=Yorkie Dad;1572439]Mardelin's comment
"No bearing" is a bit too broad of a statement. Some bearing would be more precise. It is really mostly a matter of statistics. Traits by either parent are more likely to be passed on to the descendant. In this case, using a smaller male is more likely to produce smaller pups then using a larger male. Size is determined by a suite of genes so as Mardelin implies, using a small male is not a guarantee that the pups will come out small. The best predictor for the stud will be in looking at what he has already sired.

Yes, probably a generalized statement.....but, without conducting a class on genetics and line breeding, it was probably best to generalize.
I have a very diminutive small male (line bred) that I bred to one of my females (6 1/2 pounds and line bred)......that throws pups between 5 & 7 pounds ( throws his dam and sire).
I bred the same female to a 6 1/2 pound male (also line bred) pups were between 3 1/2 and 5 pounds......
Attending several genetic/breeding classes and with a piece of expert advice given to me by mentor (40 years of breeding/exhibiting with over 100 Champions that she alone has finished).....if you happen to see a sire that you like, it is best to go back to his sire to breed to.....after all he is what threw what you liked.
