DANG

!!! What a rude person~! I can understand wanting to write instead of calling, I get nervous too, but she should have sent the letter WELL in advance of your upcoming appointment. And to groom them three times, THEN say she's not comfortable with puppies? WTH?
I feel for you, the groomers are so busy this time of year and it'll be hard to get the babies in before Christmas. BIG hugs to you and your babies
