Do you think that dogs can communicate with each other as we do? My dog and my next door neighbor's dog love each other. When they were puppies, the would dig under the fence and go to each other's yards and play. When they got big, they couldn't cross over anymore. What I noticed now was they would stick their head under the fence and make weird noises that I haven't really heard dogs make. And Cocoa (my dog) would make this weird moaning noise and Rosie (neighbor dog) would make the same noise. It's nothing I've heard before... it was strange, but so cute! I have a picture if you guys want to see!
