I am the current proud owner of a blenheim Cavalier King Charles Spaniel. I am about to adopt a rescue dog. Her surrendering family says she is also a purebred Cavalier King Charles Spaniel. However, she is described as "SOLID very light brown". (I am fine with a mix, as long as she is a good pet.) Out of curiousity, could she be a purebred Cavalier? Has anyone ever seen one that is light brown? Is it possible she is a very light ruby? I know that rubies start out lighter as puppies and darken as they age, however, she is an adult (will be 2 in May 2008). If you don't think she is purebred, does anyone have any suggestions to what mix she could be??? Thanks so much! BTW, I don't have any pictures.
