Have a 110 pound Rotty. At about 2 y.o. he began to get a little unruly. Not mean or vicious, just hard headed.
.....and when your best friends come over and your 110 pound Rotty begins leg humping your buddy's 95 pound wife 😖, it's time to take action.

Took about 6 to 8 months to come full circle and the drive to drop off, but he's much calmer now and is much more obedient! .....and the neighbor's wife isn't concerned about getting raped when she comes over!
