Aside from the whole inbreeding aspect, my advice to you would be to take some more time and figure out what you want to do in regards to long term goals before you continue breeding. Looking back, you seem to have gone through quite a few dogs in a short amount of time. Correct me if I'm wrong, but....
8/06 You got male Lilo, 'after searching for years to find the right one'
9/06 You got male Vegas (10mths)
Sometime between Sept and Dec you got a female (Chanell)
12/06 You put Lilo(?) up for sale after having already rehomed Chanell
4/07 You posts about having a female (Bell, 10mths?) in heat
The girl weighed under 4 pounds and you decided to breed her anyway--she had her litter in July, a week early.
8/07 You are looking for another female
I *think* I got all of that....
No offense, but you seem to be rushing into things rather than taking the time to study and learn. Find a experienced, reputable breeder (not one that experiments w/ inbreeding) to mentor and guide you.
You will not be sorry.
