I do see your point WG, but I did take offense. It seemed that the OP did not think that someone with a Russian background was capable of taking care of pets as family members.
I respect the fact that he/she wants to do a background check on anyone who is purchasing his/her puppies. That is admirable as many people just want to get the pups out of the house. At least this OP is caring enough to make sure that his/her pups get a loving home and live long healthy lives. I have gone through similar background checks when adopting my fur babies, and I would not have it any other way. One of the ladies I adopted my lab/aussie from still calls me every so often. She was adopted 9 years ago. She calls because she cares about the dogs she adopts out.
However, I was not required to list my genealogy on my background checks.
Again, it is admirable that the OP does care enough to make sure that the dogs go to good loving homes.
