My 7 month old female GSD is a great dog! She is an awesome family dog, she does know basic commands! I am experiencing some problems though. Every time I am outside and I turn my back she climbs the fence! It's like I cannot keep her in the yard! I have been told when she gets out she goes to my neighbors yard, climbs the fence, and attack their dogs then leave! I honestly didnt know she was like this! She is so sweet and loving, I hardly ever hear her bark! How can I stop her from climbing the fence? Why would she attack another dog? How to correct this behavior?
