So I adopted a dog this past weekend (have had him 5 days now), and he is the most adorable and loving guy. I am attempting to implement the two week shut down. He is just over 1, and he has never been consistently disciplined. I read that during these two weeks you are not supposed to train them. However, he has a nipping problem. I know this is not unusual behavior but I am having a hard time stopping it and yelping and ignoring him isn't working. He is 50lbs, so he is not small and he is strong. When I take him outside on the 6ft leash he is usually ok, but on the long lead (when I am not directly controlling him) he will sometimes come charging at me to play but he starts nipping me and it hurts and is very difficult to get him to stop. He occasionally does this in the home as well even on the leash, but it is less likely. In the spirit of not heavily training him during these two weeks and just letting him adapt and bond with me, how do I handle this? In the case of the lead, would just walking out of the range he can reach send the wrong signal to him? In the house I do not want to crate him when he does this, because his crate is his sanctuary but I feel like it's too soon to put him on time out and redirection does not always work (I am still trying to find a toy he will latch on to almost every time). Any advice is much appreciated.
