Dogs bark because they really do have something to say. Barking may sound like just noise to us, but dogs can say a lot of things with their bark. "That guy in the brown uniform is coming to get us!", "Help! My head's stuck through a hole in the fence, and I can't get out!", "You're home! I'm so happy to see you! I've been so lonely all day!"
Barking is just one of many ways that dogs communicate with us. Dog don't just bark for attention, they bark to warn us of danger and when they need help. Who can forget Lassie's warnings? Bark! Bark! (Translation: "Timmy's in the well!")
Dogs bark when they're excited, and sometimes they bark just for fun.
But here's something maybe you didn't know! When you yell at your dog to "Stop barking!", they get even more excited! "Cool! My owner's barking back at me! Now we can have a real conversation!"
So, that's why dog's bark.
If your dog is doing a lot of barking, the last thing you should do is bark back! Now you have a solution . . .
