The A/C professional was afraid of dogs

Our dog is totally unusual when it comes to people coming to the house, for some reason when there are plumbers, heating as well as air conditioning professionals, or other contractors who come to the house, he freaks out as well as barks at them when they are coming to the door, then usually if the people are new to the home as well as our dog doesn’t think them, he absolutely goes nuts, that is until we invite the man into the house, as soon as the man gets in the house, our dog totally switches up the tune as well as abruptly wants to play around and be nice. There is a slight problem with our dog jumping on the people, but other than that he doesn’t try to bite or act ferociously at all. Oh man, we had a new HVAC professional come out to the home recently and the guy practically looked like he was ready to run when we were trying to let him inside the house! It was hard to contain our dog. Even when we temporarily put him in the guest kitchen, he managed to split the door open as well as went running for the HVAC professional. The HVAC professional screamed in fear but our dog only licked him as well as was acting friendly, but we had to explain to the guy that our dog is absolutely absolutely nice to people when they come into the house, he was still cautious around our dog despite the fact that he went to take care of the HVAC maintenance as well as then abruptly ran on his way when he left the house. He was afraid our dog would begin barking at him again, but our dog kept his cool.
