How are you going to help your bitch and puppies if something goes wrong?
Do you have homes for all the puppies, before you do the mating?
Homes spoken for four months or more before the pups are ready to go to their new homes suddenly disappear, and you are left quite literally holding the baby growing into a delinquent.
Do you have the resources to look after any unwanted puppies?
As above, one puppy is usually great but more than one of the same name is a disaster area. You will be ready to GIVE them away to the first person who walks past your house by the time they are four months old.
Are you available 24 hours a day for the first three weeks to act as foster mother if all goes WRONG and the bitch cannot look after the litter?
