Thank you! No they are not both mine, and not related. Spirit lives across the street, she is about 2 yrs. older than Cache, has known him since he was a was a small pup and was wonderful, so gentle with him, (although 'gentle' is not how they play now!) at teaching him appropriate social skills and how to play 'like a border collie'.I love those pictures! Well photographed 😉 Are they both yours? Related? They are so beautiful against the white snow background.
