I do not know what it is, but any dog that has lived with me or I have whelped is a cuddle bug with other dogs. Mine are always in a heap together. I always thought it was just the Whippets using their hairier brothers and sisters for warmth, but apparently not.
Thanks for the kind comments. It is lovely to know otthers find them sweet too.
I hope she likes the snow because they get lots of it. The day before this was taken, her Dad and some other men were all day digging the cars out, and a path to walk in and their driveway. All of their dogs romped freely all the time they were doing it. They had five foot drifts! YUCK! So I reallly hope this little lady learns to love it.
