That's one thing I learned about owning this breed is that they will have to be worked or you will run into problems with your neighbors (if you have any) or you will be spending money repairing dog houses/water buckets. The more I exercise mine the less they bark @ night, less digging, and no more chewing on the shade board from my young male who likes putting his mouth on any and everything. This joker worked the hide on the springpole for 40 minutes straight yesterday and didn't wanna let up on it and was screaming to get back on it once I got him off. I figured that it was a good enough workout (being that he is just 13 months old) and to my surprise he just took a sip of water and started running the chain spot like he was fresh again. He goes APE when he sees a piece of hide, a riding mower, or a shovel for some odd reason. Lol. With out the long walks and spring/flirt pole work, I would be in trouble. The good thing is that these animals keep me active as well.
It doesn't always work like that imo. Some dogs never cause any problems in their life until you start working them/giving them attention. Then they'll demand it every day and start making noises. I think a stable dog that didn't went trough many changes, and who has a proper kennel or chain setup won't be stressed like that. But there's a allot of natural monkey dogs also of course who're trouble no matter you work them or not.
Another thing to look at is the digestibility of the kibble your feeding...1 cup can equal to so much caories, but that does not mean he is digesting and obtaining all them calories.
