I have a dog & I work al day I leave at 07:30 & return at 17:30! Yet my dog is very content! He is walked before i leave & again when i get home. He is given a kong toy filled with treats that takes up some time, waits to bark at the postie & then mostly sleeps. The neighbour only hears him that once! He has never destroyed anything. He was a resue dog & compared to a kennel he is now living in luxury!! He is healthy, happy & very spoilt!!
