Harley is our newest addition. The best guess I can come up with is Chow/Border Collie or Aussie and who knows what else. One of my husband's relatives had her and her sister, two 1 year old Lab/Heeler mixes they said. They said they didn't have enough time for all their pets and wanted to rehome Patches(as they called her). Of course, we couldn't say no. Harley reminds me of a mixture between Zeke and Mudflap. She is moderately high drive, almost as obsessed with frisbees as Z used to be with tennis balls, loves to snuggle, and is very smart. And she's also a pansy, lol. She is very easily discouraged and not very confident yet. She is very ornery. When all the dogs come in, most of the time she comes right in with everyone else. But once in a while, she waits. So I'll give her a second chance and call her again. The first few times this happened, when she didn't come I went over to her to make sure nothing was wrong. She tried to entice me in a game of chase and looked quite pleased with herself. Lol, so she's learning now that that will not work and if she doesn't come in when asked then she gets left out all by herself. She also thinks that a barking fit will get you to throw her frisbee, so she's learning that barking is only rewarded when asked to bark, and any other barking ends the game. She is definitely an ornery brat but I love her to death. Her manners are coming along quite well. She loves cats and is very, very sweet to my cat Elli, who is still adjusting to all the newness. Harley is going to be a lot of fun to work with and I am really looking forward to watching her develop. So far, she knows: Sit Speak Jump my leg Shake High-Five Get up/Get off Here she is!
