Border Collie/Dane cross? That ought to be interesting. Does it still herd everything in sight?
No, just herds our other dog, a lab/feather-haired retriever mix.
The only true traces of "Dane" in him are an ever-so-slight jowl, a longer body and most prominently, his legs that make him really tall. I don't have to bend down to pet him -- his head fits right under my hand when I am standing.
Personality-wise, he is a very affectionate goof-ball with the family, but a real watchdog with everyone else. He does have "Rainman", obsessive-compulsive tendencies, but the most destructive side of that has been trained out of him. I can leave him in the house all day by himself and he doesn't pee, poop or tear anything up -- ever, inside. On the other hand, outside, he tore up most of our landscaping. Luckily we were "under construction" at the time and were going to redo everything anyway.
When he was a puppy, he easily did a thousand dollars worth of damage before he was six months old -- and that was my fault for underestimating him. At about five months, I did have a few serious thoughts about giving him up, but as soon as I even thought that, he turned "Mr. Perfect" (almost) and I am so glad that we got through that and I kept him. He is, however, still stubborn as a mule. He is a dog that you "partner with", and can never dominate completely because he doesn't back down when confronted. Not necessarily a bad thing, given that we are in a rural area.
