i know you said med.size dog but i just have to vouch for the pitbull. i had a large, very scary looking red pit w/ yellow eyes. he was extremely smart and protective. all he had to do was look at someone with those wicked eyes and even the biggest,baddest man [or animal] would run. but to my family and 2 year old son he was a loyal, loving family member. we lost him in Nov. but if a pitbull is raised responsibly, i think they are the best all around breed. good luck with your decision...
