I have 4 Shelties, and they can be kind of obnoxious to visitors (in an attention-demanding way). If the pastor was an invited guest, and I knew that he wasn't fond of animals, I would allow them to greet him, and then put them outside or in another room for the duration of the visit. However, if he just happened to drop in, I probably wouldn't put them away--especially if I wasn't particularly interested in having visitors...
