When I talked to the woman she did say that it's just the way she was made up; I do know the dog is pretty active and the owner seems very friendly. She has had three huskies stolen from her yard (among other things) and her son had this great dane mix so since she had a big yard and no other dogs she brought him over-for both companionship and protection. I don't think she is doing anything wrong but I just thought it looked skinny-but again I understand the breed. She is a pretty dog though...I love great danes and greyhounds-it's pretty interesting seeing the mix.
