29th OF MAY would be 8 weeks and 3 days (59 days) and give the new owners Memorial day weekend home with the pups. The last 5 litters of Viszlas I did we shot for 8 weeks. So I guess we agree. Sorry for the 1 am Tequila math. I took Mickey home at about 52 days with only one pup from the litter left at the breeders and she survived. I am not to worried about it. I have herd the 49 day thing helps pups to bond a bit tighter with the owner but it does seem a bit early to me. If the new owner felt strongly about it and could show a bit of supporting evidence I wouldn't fight it to hard.
Thanks for your concern...Art
