We would like to get to a point where our dogs are able to be out of their cages while we are at work. I goto work at 530 and come home around 730, then I leave again from 0900-1130 and 1330 till 1700. My wife works 0730-1500. So the longest time they would be left alone in the house would be 2-3 hours tops. My only problem is my chocolate lab likes to chew on the corner of the wall. I constantly correct him if I catch him and hand im a toy. Is there another way? He also likes to chew on our coffee table and chair legs. My wife is getting very frustrated as am I. I know he is still a pup at 7 months old but there has to be something I can do. Any suggestions? I also know he is too young to be left alone, I jsut want him to get used to it for short periods of time. Thanks again.
