Quick spell check - on your Breeding Connection page it says to "Post your puppy's for sale here." It should be 'puppies'.
You might also consider making it so that the breeder can post contact info and a website, but not an actual ad for puppies. Otherwise it might seem too much like a 'next day pets' type of thing.
Also, your link to Sit Means Sit should go to Fred Hasen's main page (
SIT MEANS SIT DOG TRAINING).
I might also recommend the following article in its reprinted form. It's called "Why Not Seven Weeks - The Forty-ninth Day Revisited." It's about why it's better for pups to stay with their litter longer than seven weeks.
