i think what we call exercise is learning and mental stimulation to a dog , a bored dog is a problem dog ....... as far as place stay , sit , lay down commands , unless your with the dog , or can tell him place and go to work , that really is as "temporary" as exercise ....... most everything my dogs learn is through exercise , they know to walk on a leash without pulling , they know stop , they know stay , i can tell them which way to go on a trail , or which side of a tree to go on , they know what side of me to walk on , they get socialized with strange dogs and people , they learn to ignore distractions , learn how to act in the car , learn how to act in leaving and arriving at my our house ............. as far as problem home behavior , give them acceptable stuff to do let them know what's unacceptable and you won't have a problem , i never have , i'm not a trainer and my dogs are absolutely not the sharpest pencils in the box ...... as far as enzo , i would say taking his dog to the dog park is a lot more involved than just taking the dog to the dog park ....
