Yes they are. My beagle is very loud and very silly. I got him a baby sister a few weeks ago. An 8 week old mini goldendoodle. She has been trying to imitate my beagle's bays, but only ends up howling. It's so great lol. He is so concerned over her and gets very jealous of I give his sister attention. He's not upset that I'm giving her attention, he's upset that she isn't giving him attention.
