I learned that some (not all) yappy dog owners have literally tuned out the incessant barking and sometimes truly don't even realize how annoying their barking dog really is...especially if they are home a lot with that pet.
We have a neighbor who I've posted about before on here, whose dog not only roams the neighborhood and pees on everything, but also barks without mercy at what appears to be NOTHING.
I've gotten to know them a bit more since that time and finally said something to her while I was over visiting one day. We were sitting there chatting and yappy was going on and on and I finally said "I'm sorry, but I have to ask...how the hell can you stand that?" She goes "what..??" I said "the freaking non-stop barking!" She goes "oh my gosh...I'm sorry, I don't even notice it anymore...he's been like this for 11 years, and I don't even hear him anymore".
She is a SAHM so she's home with him all day. It wasn't 15 mins later her husband came home from work. After about 2 minutes of him being there he comes out of the bedroom and shouts "for god's sake yappy...stop!!!"
She started laughing (and so did I) because again...she has completely tuned him out. I told her - from now on I'm just going to call or text her when he's outside and needs to be tended to...and she thanked me because she honestly didn't even realize how annoying it is to others who aren't accustomed to hearing it day in and day out.
Either way - I agree - it's VERY annoying and for sure needs to be addressed. I was just posting this to realize it may not even be intentional as far as neglecting the barking.
