boxers dont require much exercise, but do need a good walk once a day. they are family dogs so need company but are very smart so need training (as do all dogs). if you set the ground rules early and get them trainined (well, i did it myself, and my two are little peaches) then you shouldn't have any problems. i don't think it's very nice for them to be left alone during the day, but i'm a fulltime student so not home much, but they tend to sleep all day and then go crazy when i get home. like badger said a walk in the morning is best to wear them out, but it all comes down to what they're used to, make sure they wont suffer from seperation anxiety as otherwise they will become destructive. other than that, provide lots of stimulating toys like kongs, treat filled rolly-balls and a comfy bed to sleep the day away in. all dogs start out like little demons though, chew chew chew, bark bark bark, comes down to your commitment to their training, its hard work but the rewards are a best mate that knows the rules, and love you to pieces!!
