No, not Rumor. A friend asked me for advice, and I figured I'd pass what he told me on to you guys to get even more insight/advice. The information he gave me: he is fine with the immediate family. and fine with MOST people... however it seems as though he seems to have a problem with men. particularly older men. he literally pulled Doyle across the yard, and ended up snapping at my neighbor. neighbor is cool with it. (this time). there was nothing doyle could have done to stop it. the thought of a muzzle seems possible... but would really only be a bandaid for the situation. he's a 2 yr old chocolate lab that we adopted the week before h2o. i assume this stems from incidents prior to us getting him. if anyone comes in the house, he barks, and the hair is up on the back of his neck until he figures out who is coming in. a friend of ours (female) can come in and feed him without issue... if her husband comes in with her - he is a bit more aprehensive about the whole situation. i am assuming that a man did bad things to him in the past. i however have never had an issue with him though. Thanks.
