My boyfriend is probably going to end up getting this dog. She currently belongs to a family member of his who is needing to rehome her. We are both trying to figure out what she is and can't quite pinpoint her breeds. These 2 dogs are littermates. The brindle one is the one who will probably end up his. Their current owners were told when they got them that they were Lab/Heeler mixes. Not so sure about that...and that definitely doesn't explain the brindle! So, info and several pictures... They are around 1 year old. They are roughly 40-45 pounds. They are very high energy, though some of the pictures suggest otherwise, lol--the pictures were taken after looooots of frisbee play. I haven't gotten to see her yet, just these pictures. Anybody have any input as to what she could be?
