This comes up OVER and OVER on breeder groups, and you do get a range of responses, with a few breeders not allowing visitors. Here's the thing: parvo can kill a puppy, but so can undersocialization. IMO there are many ways short of keeping puppies in a bubble for 8-10 weeks to protect them from parvo and other diseases while providing a stimulating environment (i.e., outdoors and a variety of surfaces) and lots of human interaction.Is there really risk of Parvo if they let too many people visit the facility? One breeder is saying that is the reason that you can only come on visit day
The other thing to understand is that assuming the dam has good immunity from parvo and distemper, and assuming the puppies got adequate colostrum (first milk after whelping), the puppies will have good protection via maternal immunity for some weeks after birth. In fact, that's why you need to give a series of parvo/distemper shots to puppies--to make sure that one of them is given late enough that it isn't overridden by maternal antibodies. That is a long geeky way of explaining that although I don't want to introduce parvo into my house, I also don't see visitors as walking parvo bombs. I'm more worried about my breeder friends who have been tromping around dog shows than I am my non-dog friends and other visitors.
So I welcome visitors. I ask people to wear clean clothes and make sure they haven't recently visited a dog park, a dog show, or another breeder's house. Visitors remove shoes and wash hands.
Last year we lost a wonderful toy poodle breeder, Gayle Roberson of Poco a Poco toy poodles (BEST kennel name ever!). But her website lives on, and includes some great advice on shopping for a puppy.
