I might be a dog, but I know how to communicate effectively with my people. I can make a lot of different growls and barks, and I've trained Mom and Dad to hear all the nuances and know what I'm saying.
There's my "airplane going over" growl. It's really short and quiet. I don't like it when airplanes fly over my head. Mom says there is nothing we can do about it and I should stop complaining. She's probably right but I'm exercising my first amendment rights and expressing myself.
I have different growls for when deer or fox or crows are in my yard. When I bark and growl, Mom and Dad know more than one critter is around. When I just bark, they know whatever it is is close to our house. Then there's a different bark when someone is coming back the lane. That's a fast and loud bark. When I'm outside I talk to the neighborhood dogs. That's a loud and long bark with a pause to hear a reply before I do it again. I'm the local boss. Sometimes I tell everyone to shut up and be quiet and they listen to me. Mom thinks that's funny.
When I bark in the house, Mom tells me to use my inside voice. I don't think so. Just like I know words and phrases Mom and Dad know growls and barks. It's a pretty good system.
But sometimes I just need to tell Mom something special like how much I love her. Face-to-face is best for that. Mom says I'm special.
I'm Deuce. Of course I'm special!
