Meet Shadow. She is a sweet 3 year old weimaraner. Not only is she the most intellegent dog that I know, but she is a great mommy dog. Out of 4 litters of no less than 6 she has not lost one. We gave her the nickname Houdini because we used to try and lock her up or put her on a runner while we were away but she will not stay on them. It's hard to have a dog smarter than their owner.
