I have had chloe since she was 12. She barked occasionally for the first 2 years i had her. But in the last 3 years, i dont recall her barking at all

I guess its because of her age
Did you ever notice that if a small dog barks even for a moment, they are cnsidered annoying or yappy? While a larger dog could bark all day and night but wouldnt be labbelled?
When my neighbor moved next door 4 years ago, they had a black lab x. Of course their was a fence seperating the 2 girls, and they both charged it barking. The lab barking more, and more loudly then chloe. My new neighbor sharply said. "I cant live next to a yappy Mutt! " I was stunned. It was all chloes fault in her eyes. I dont understand, A dog is a dog, wheather its a 90 lb lab or a 6 lb yorkie. They are both gonna bark when they feel threatened!
Thankfully my neighbors moved away again in 2 months time. Ironically, they couldnt deal with the complaits the neighbors were making against THEIR yapping dog.
I believe that is called poetic justice.
