I have had dogs tear apart wire crates..my sister's gsd ripped apart a sliding glass door....I have a friend who's one dog jumped through a closed window to get at and attack their other dog...please DO make certain any containment system is extremely secure. As mentioned before, dogs not living together may tolerate each other but once under the same roof, dominance and territorality start kicking in. Is there any way you can have friends or family watch YOUR dog while you are keeping your friend's dog? Same sex, same age...and we never found out if either of these dogs is neutered...and with your boy starting to reach adulthood...all can have the potential for a disastrous outcome. PLEASE do not put your boy in any kind of jeopardy...again, make absolutely certain both dogs are securely contained separate from each other at all times.
People are passionate about it because they understand the probably outcome of this.
