LOL I don't have four YORKIES - but I do have 4 DOGS
2 Yorkies and 2 other dogs (a Mini Dachshund and a mixed breed/rescue)....and of course we can't forget THE CAT
Sooo, no...I don't think your nuts - and hey, if you are, I am!
By the way, those new babies of yours are soooo cute!! That little boy is a total doll and I can definitely see why you are falling in love with him!
Congratulations!
