well, your dogs might NOT need the daily excursions (they would no doubt enjoy however).. when you have large herding dogs, this is not an option if one is to maintain a "happy" home..
It is night/day when the pups dont' get adequate "burn off energy" time outdoors... An exhausted pet has a smile in it's soul & is gentle & fun in the home.
LOL! Good point Dolly. :) My dog is a couch potato. She gets spurts of energy and back to laying down. Although, when the weather is warmer she seems more energetic. :)
