Con Slobodchikoff, PhD, has been working with the communication and social behavior of prairie dogs. He also has been doing consulting on pet behavior problems, and has offered dog training classes.
The prairie dog work suggests that prairie dogs have a complex communication system that borders on language. They have different alarm calls for humans, coyotes, domestic dogs, and red-tailed hawks. In addition, the prairie dogs can describe the size and shape of an individual predator. This is the most sophisticated animal language system that has been described to date.
Con also writes a Dog Behavior Blog which provides tips on solving behavior problems and short essays about some of the scientific research that is being done with dog behavior.
