Basenji/Chi Mix?

[Deni]

So I rescued this little (4 lb) Chi mix, and the more I read about Basenji's the more I think she's mixed with one. She's super sweet, smart, very energetic, very athletic, has a great nose, finds lots of things on our daily walks, hops when she runs, has a wrinkled brow and almond shaped eyes and she rarely barks. Think Basenji's can be so small though?
