I believe it's called Little mans complex... LOL! Casper barks like crazy when he is around people he dosen't know. Especially men LOL It was cute at first but not it gets out of hand. I have noticed though that since we have been taking him out more lately he's been a little better. My boyfriend and I went to the lake last Saturday and took Casper with us and he was the best boy i was so proud of him! Especially since there was a little Pomerainian (sp) who was barking and barking at Casper and all he would do is wag his little nob and try to be friends with him...
