I have several that are quite vocal when they want something. If I forget to give Dixie, age 12, her morning cherrios snack she make a cute woofing noise until I figure out what she wants. Bebe always lets me know when it is snack time at night, she is the spokes doggie for all of them. She can drive me nuts with her woofing noises. It does not matter to her that I might be trying to watch a show or reading on the computer. She is like a clock, come 9:30 p.m. I better swing into action.
My Little Man is the only dog I have that does not bark. He is 10 years old and I have only hear him bark maybe 2 or 3 times his whole life. He just make a cute little whining noise when he wants something. They all talk in their own little way.
