Funny the things that dogs get emotionally attached to.
My first Akita got an unreasonable attachment to a Winnie the Pooh bear that he slept with, wouldn't let anyone sit next to (it was enthroned in one corner of the couch) except me (grudgingly) and oddly enough my mother. For years he wanted to bring it with him on our every single walk, but I put my foot down about that after the first time since once outside he dropped it and made me carry it (rather embarrassing, that). First thing he'd do when returning from a walks was rush to the couch to be sure that Pooh was unharmed in his absence. I got used to telling people that came over for the first time to not sit next to Pooh bear. That very much upset Kato, and he'd rush to protect his Pooh by shoving himself between Pooh and the person and glaring at them.
After he passed away, Boo, my next doggie inherited Pooh bear, but he wasn't the least bit emotionally attached to it and promptly ripped it to shreds which he did with every stuffed toy he got. Yoshi likes to beat up on his stuffed toys and only injure them enough that I have to fix them... and he will bring them to me to fix and insist that I do it (and insist that this be done immediately while he watches and waits) only to injure them again. I think I spend part of almost every day stitching up one of his injured stuffed toys.
