When I was with BEAR rescue in OH, I rescued a young B/Sheltie female Mix from a Columbus shelter. We went lure coursing in PA and stayed at a motel that had waterbeds. This girl was under the covers along with the Bs and in the middle of the night I woke up to hear panting. This crazy girl did not know any better than to get out from under the covers to get cooler. I had to physically pull her out, get her some water, and put her on top of the covers to cool her off! Even though she had a narrow snout like a Sheltie, a slightly heavier coat than a B, and a looser tail, she had a running style like a B and loved to chase the lure. There was a picture taken of her lure coursing. She also like to retrieve balls which none of the Bs would do. She was a sweetie and was eventually adopted.
