I have had large dogs and small ones For 2 weeks i would need to use a crate after that they were trained, be consistant on time you feed them every day and until they were trained I would pick up there food by 6 pm, within 5 min. of feeding we would go outside for a potty break. before they got full run of our house I was always leery of chewing , I would leave them alone in the house shut the extra doors and watch from the outside of the window to see if they were going to start chewing or get in trouble. I would take 2 weeks and devote that time to get them trained and it has always worked for me, best of luck and enjoy your new little buddy!
