The only thing i know ladys is that when i dont walk any of my dogs ,when i get home ive got plants ripped ouy ,dog bedding everywhere ,washing line pulled down ect ect ....in my book this is what you get when there not walked enough ! pork chews are good like pigs ears ect ect ! But the bottom line is if you dont walk him enough and your not there, then they end up getting bored and distroying your house !
