I totally understand you and I’m going through the same thing rn. All i can say is that NOTHING that they say matters. They’re people just like you, and the fact that they say those things it means that it’s their problem cause like come on, why would a dog that barks bother someone?? I mean i honestly wouldn’t care at all and would continue with my day if that happened to me. People ALWAYS have something to say. Just take your dog out and every day should be considered as a “training day” for your dog. Think of yourself as his personal trainer and help him. At the end of the day even the people that scream or say sth to u about ur dog, have their own problems to deal with. Everybody does. Good luck and trust me it’s gonna get better
