The most fascinating behavior of Alvin's is how he watches other dogs and then imitates their behavior. It is often behavior that he wouldn't think to do otherwise. When watching videos of him in his previous foster home, I see so many examples of behavior that I haven't seen a hint of while here. I am attaching a short video that illustrates the point. Eli is the main focus for the first part of the video and watch his body movements. At about the 38 second mark, Alvin comes bounding in and you can see him imitating the same bouncing behavior of Eli. Well, Alvin's isn't nearly as coordinated but you can see how closely he tries to imitate it. Then there is the toy in the mouth, which he regularly had a toy in his mouth while living there. As previously mentioned, I have a basket full of toys and I can't get him to play with them and I suspect it is because there hasn't been a dog here that ever played with toys around Alvin. From living with Alvin, I can't tell you how different his behavior is on this video and there are plenty more with similar behavior captured. It fascinates me to no end. Take a look and if you have any insights or observations, please share them.
