One of the best things about adding a puppy into a family where there is already a well mannered dog is that the new pup will pickup on good manners from the already established dog in the household. Well, it's the total opposite!
Kyuubi is very easy to direct. If he's chewing on something he isn't supposed to and there is a toy near him all I have to do is make the sound "ah, ah, ah", he stops what he's doing and goes after the toy or if there isn't a toy nearby I bring one to him and he forgets about whatever he is chewing on and goes for the toy.
Taking my dogs with me everywhere I go, I always have a bag full of their toys, treats, poo bags, etc. so little Kyuubi thinks it's okay to chew on the bag that has his goodies in it. Mika did see him chew on the bag, and she also saw me redirect him to an appropriate thing to chew on. Then an hour later when I put Kyuubi down for a nap, I find Mika chewing on the bag now! Something she's never done before. Oh well, doggy see, doggy do.
