I'm asking because my in-laws are wanting to come visit with us for Thanksgiving and Christmas. I have no problem with this, but they have two very out of control mini schnauzers. They have no money to board them so they are wanting to bring their dogs with them. They would be crated, but honestly they drive me crazy with their constant yapping and hyperness. Also, the male is very dog aggressive but my in-laws are clueless. They think that his behavior is cute and do nothing to stop it. They also have asked many times to let Gunner meet them and play with them, but obviously that's NOT happening. Gunner is not dog aggressive, but if their male terrier challenges him, I know what would happen. Okay, so my question is...should I allow them to bring the dogs and just deal with it for a few days, or is there something I should be concerned about regarding Gunner? Even if we keep them separate, could having another aggressive male dog in his home and using his yard cause issues? I want them to come visit, but I really dread dealing with those dogs. I also know that they are clueless though and won't understand my reasoning for wanting them to stay at home.
