Just curious. It seems every dog has things that they pick up with almost no effort, like loose leash walking or certain commands or appropriate behaviours around the house ...and then there are other things that take forEVER to catch on to. For instance, my friend has been teaching her pitbull to drop the ball when he brings it back to her...FOR SEVEN YEARS and he still doesn't do it reliably. But some other dogs just naturally drop it without a moment's thought. For myself...Nova was a dream in the car from day one. She lays down and goes to sleep right off the bat. We didn't have to do any of the exhaustive "little bits at a time" thing I know a lot of people have to do to have their dogs ride happily in the car. HOWEVER, she has a huuuuge blind spot for using her mouth. The other puppies in puppy class were gentle will their mouths from like...3 months on, no one had any problems with it at all...not my little land shark though! She just doesn't put it together. Even our private trainer said she's WAY harder with her mouth than most other puppies and that she seems to be extremely orally fixated. So that it's going to be some work for us! So what did your dog figure out in a heartbeat, and what does she really, really have a mental block for?
