[Breeds] Can anyone help me identify what breed my dog is?

http://ift.tt/2rIn8bS is Willow. She is a 1 year old and about 35 lbs. I've had her since she was 4 weeks old. I was told she was corgi/red heeler when I adopted her but I'm not quite sure of that. Can anyone help out in identifying her? via /r/dogs http://ift.tt/2sGK5JT
