@knittedspoons I totally get what you mean, my dog is reactive towards strangers in certain situations. See a stranger on a path while walking, he's fine. Us ordering food through the drive-through, he's fine. He sees people working with lawn equipment or roofers, he's fine.
What he isn't fine with, is random people that are meandering near us. One example is while we were on vacation, I took him out to go potty. He's about to do his business, when we both see an older woman carrying a cup of coffee walking towards us. He starts barking, she gets closer. HE CONTINUES TO BARK AND SHE GETS EVEN CLOSER.
At this point, I knew that he will not use the bathroom and I try to walk away to put distance between us. SHE FOLLOWS US. Starts talking like "oh I had a dog who barked at everything, oh he's so cute, oh what's his name". Like cool you aren't scared of my dog but he doesn't want you near us.
I had to carry him back to the AirBnB and try again in 30 minutes.
So I get your frustration and I empathize.
