Brody was a mouthy little so and so when we got him, but he had never been taught any manners, so we didn't hold it against him. After a few months of training, most of his nipping had pretty much stopped. He still uses his mouth quite a bit to "communicate" with us. Sometimes, if he needs to poop and no one is paying attention, he will come up to me and very gently take my hand in his mouth and pull me a little. I don't really mind this, as I would rather him get my attention this way than bark, or just give up and poop on the floor. Sometimes, he just seems to want to hold our hands in his mouth. No pressure is applied at all, but he will take someone's hand and just hold it. This is a little weird, but not really troublesome. The problem comes in when he needs to communicate something of a more serious nature, and uses his mouth to do so. Last Sunday, Brody was lying in the middle of the kitchen floor (one of his favorite spots when any cooking is being done) while my husband was cooking. All was fine, until hubby needed to toss something into the trash inside a cupboard. In doing so, he accidentally stepped on Brody's front paw. He was wearing shoes, so he had no idea he had done it, but I saw Brody lift his head and put his mouth around my husband's ankle, then remove it quickly without him even feeling it. A few minutes later, hubby moved quickly toward Brody, and Brody went for his ankle again, same as before, but he got caught that time. Hubby was surprised, and I explained to him what had happened, that he had stepped on Brody's foot and now he was scared it would happen again. Yesterday, Brody was lying on the kitchen floor in front of the cabinet where we keep our microwave. Hubby stepped over Brody to get to it, and Brody stood up and took his hand into his mouth. Hubby was very disgusted (he HATES dog saliva on his hands!) and loudly asked "Why did you bite me?" Now I know Brody has a history of biting, but this was a very different scenario, and he didn't cause any pain whatsoever, it was just the "hold". He does the same thing to me when I try to get him to back up when we are walking side by side, as I have stepped on him a few times when his back end curls around behind me. If I can't teach Hubby to respectfully get Brody to move out of the way when he wants to use the kitchen, then I need to teach Brody not to use his mouth this way. (I know I should probably also teach Brody not to lie on the kitchen floor, but it is the only floor in the house, other than the bathroom, that is not carpeted, so he likes to lie there when he is cooling off after play time.) With the nipping and mouthing he used to do, it was so frequent and bothersome that it was easy to remember to pull our hands out, stand up and turn our backs on him. Everyone was on board and it sent a clear message. The way he uses his mouth now, it's so subtle and gentle that we hardly realize he's doing it until a few seconds have gone by, so pulling away isn't as effective.
