i'm sure there are some boxers that are a few cans short of a six pack - but as a general rule (we have probably 10-15 boxers within 6 square blocks from me) they're smart. not 'teach them how to count' smart, but they're very eager to please....so long as they recognize you as the pack leader. that's the part about boxers (and other working/guarding dogs in the same category) that's tricky. feeble/wimpy/non-dominant people don't make good boxer owners. i'm 6'2", 250 pounds...with a loud, booming voice. i don't yell, but there are times they both jump with i'm not happy with what they're doing.
