Crying Babies

Louie is a new addition out at Templeton Equestrian Center. He is an 8 week old Boston Terrier now owned by my trainer, Michelle Merkin. She got him on Sunday night and brought him to the barn Monday morning and boy did he cry! The interesting point to all this is the reaction of the mares at the barn. They were beside themselves. Maddy just kept looking in the direction of the cries and got all flustered. I didn't get a lot accomplished because she was so worked up. I just thought maybe their maternal instincts kicked in. Either that, or they were just scared at the sound. I don't know which. Has anyone else had a similar experience with "crying babies" and horses?
