Achilles doesn't bark a whole lot either however he nearly attacked my mom one night when she came to visit. My mom was in my room and Achilles and i were asleep on the couch. Apparently my mom woke up to get something to drink and Achilles let out the most ferocious bark i had ever heard. My mom and i both had to calm him down cause he was going off....

Guess he forgot mom was staying with us and thought she was a robber!
