My mom's dog was so sweet and quiet until he hit around 1 year. Now he is quite vocal and barky and he is driving me nuts!

My theory is that when he is barking, he usually is trying to tell us something and if we figure out what it is, the barking will stop. My mom's theory is that he is barking to get attention, so we should ignore him. Let me know if you have any advice for us!

Do you have a barky dog? How do you deal with it?
