I don't have any pups at this time and usually only have a litter every 2 or 3 years, but get emails everyday asking for pups. Most of them ask for a teacup, which I then try to respond and educate them so they don't get taken.
Many of the emails will give a one sentence question - If you have any pups - how much? Plain and simple. I try to email them back and just give them my website and hope the information page will help to educate them.
I also screen prespective parents too! I prefer to speak to them, because they are more likely to be more honest and if something isn't right - they will usually slip up. It is easier to feel out what type of parent they would be in voice or person.
I just feel really responsible to any babies I bring into the world and want to make sure they get the best - forever home!
