Your pictures of the two of them sure are cute. The chocolate color is easy to get patchy when crossbred with some other color. He sure sounds like a neitherland dwarf cross.He has a short face.His ears stick right up when he is excited or nervous, or when he hears something. He is patchy.. I don't know how to describe his colour, but it's throughout his pelt. He's all shades of brown
The dog in this picture is a miniature poodle. So maybe you can size him based on her. Daisy Mae is the size of a house cat, and Frankle is a bit smaller than that. My dog has a thing for bunnies. She loves them.
