In my doggie experience, it takes about 2 years to make a "good dog" meaning one that has been through and given up its adolescent bad habits, has gotten some street smarts, and is completely reliable. Of course, it's a continual process, so there will be both victories and some set-backs. When the dog exceeds its limits, tighten them back up a little until it can deal with them, then you can gradually relax them. 6 1/2 mos is still really just a puppy, so expect a lot of puppy behavior, including chewing, occasional pee and poops inside the house if they have to hold it too long, etc. When you think they have gotten big and are all grown up (about 10 mo - 1 year), they start adolescence, testing again, acting just like a human teenager so don't be surprised! This too will pass and the end result will be worth it appicon
