Jose I agree with Ice.Give him some freedom.It doesn't work for all dogs or situations but you never know if you don't try.Start with short trips.
Take some time to scan all rooms he can get to.Remove possible dangers like electrical cords,lamp cords,cleansers,chemicals,antifreeze,any thing he could hurt him self on.
Daisy's had free run of the house since about 8 ?months old?Hard to remember now.No damage to furniture,destroyed a few dog beds,and an occasional pilfering from the trash can to shred some paper or something.Heck she doesn't even dig in the back yard.
Get lots of toys,balls,kongs,etc to keep that little mind and mouth busy.
Start with quick trips,like 3 minutes.Slowly increase how long your gone.
Don't walk in after being gone and be excited.Walk in almost ignoring him,like this happens all the time and it's no big deal,...because it isn't really.
He will probably be excited to see you,don't react unless it's to correct him if he jumps up or does something undesirable.Then go on about what ever it is that Jose does.He's a Dobe,he'll pick it up in no time.
