Going down.....

Anybody checked our inbreeding coi in the last few days????? It's gone down from 5.1 to 4.8 HURRAY! Ok it's only a little bit but it is definately the right direction.  But then we seem to be developing a couple of other problems.... The number of bitches missing after matings  and when they are in whelp... The size of the litter! I keep looking on Facebook and the litters on the continent just seem so much bigger that ours, nine and ten pups seems standard to them, while here it seems to average four or five pups! Any body got any bright ideas???
