I am not by far an expert, but your dog does look like it may be mixed. She is still a cutie and you should be very proud to have her. What bothers me is that you saved up your money and paid $900 to someone who sold you a "purebred" dog under false pretenses. I'm sure it took you a while to save up, as it would me, and you deserve to get what you paid for. In the end, you have a sweet, wonderful dog who is sure to bring you and your daughter many years of joy, but this "breeder" made money off of you and is probably doing the same thing to other hard working people. It is just wrong!!
