digging,,, hmm,, ok,,, now I have seen on Dr S Coren show herein Canada,, that to help a dog to dig in the RIGHT spot,,,, and still let him dig, is to make them thier own small sandbox.... encourage them to dig for toys and treats and hopefully they will catch on quickly that its okay to dig in there and not in mommys garden or grass....

the chewing,,, try giving your pup a bone or Kong ball filled with cheese wiz or peanut butter just as you leave. ,,, this might give him something to chew andwork at while youre away and give your deck a chance at .. life,, lol lol It also gives him the impression he isnt being punished by being left behind...
