We’ve had at least one person in the house (in our bubble) with zero issues but today the chimney sweep came. Django was ok when he came on the door but when the guy went into our family room to start to clean Django went ballistic. Like serious barking and growling. I did have him on a leash and did distract with food etc but holy cow. Was not expecting that at all. He’s seen people on the street as well and never reacted like this but due to Covid we’re always quite a distance away. I’m hoping this isn’t going to be a problem. Right now he’s quietly lying by my feet but he can’t see the guy; he can just hear the vacuum. Any thoughts or suggestions. He’s 13 weeks old.
