I meant that terriers can be aggressive by nature; they are very territorial. They can also be very, very sweet (pitbulls are a terrier too). One of my best friends and his wife get Bavarian Shepards (same things as German Shepards, just bigger) and they are VERY well mannered around others.
Yeah, my neighbor has a shepard/lab mix, and he's big too!! I have a feeling that our "pup' is proably going to be around 100lbs., if not more.
