I am still new to the forum, so apologies for starting two threads in my first few weeks, but I did a quick search on this and didn't see anything immediately applicable to my question.
As some of you know, we've had our new guy Lucas, our first BC, for a couple weeks. My impression is he's feeling comfortable and gaining confidence (thanks all for your help in this area!). The first few days he had a few chosen spots around the house he would settle in. Now he comes to us for affection, greets us at the door enthusiastically, and loves walks. We've started some basic training and he's picked up 'touch' really quickly. I think he's adjusting well.
He wasn't a 'velcro' dog, even in the beginning, choosing to lie around and watch as we moved from room to room. But now, it seems to me his is forming an obsession with looking out the window to our backyard. There are some baby rabbits who have deemed it the perfect place to start their lives, and I know he can see them from time to time.
But this isn't just glancing. Lucas seems to be fixating. He will stare out the window, unmoving, unblinking, for very long periods of time if I let him. During these moments he doesn't respond to his name or even strange noises I make to get his attention. If I'm not engaging him with tricks, a walk, etc. he just goes to the window and stares. If we are training, he will abruptly get up at moments to go back and check the window. His prey drive seems VERY high (but he's not yet interested in toys - no flirt pole or toys that look like animals). We've blocked the window with our curtains and he will stare at the curtains too, when they really only let in light/shadows.
Anyway, sorry for the length. Not being as familiar with the breed, I'm looking for insight and/or advice. I know BCs can be very intense and develop quirks quickly so maybe some of my concern stems from that. I'd just like to direct this energy to engaging with us more and it seems this could potentially escalate, which I'd like to be ahead of if that is the case.
