Synchronized Chompin'

Barley, a dog, sploots in a fenced yard beside and parallel with a golden retriever. Each chews a hunk of wood enthusiastically.

Barley was very fortunate to have many playdates over the summer months, and in doing so was able to share in her passion for chewing on crumbly hunks of wood. Her interest in “social chewing” turns out to be quite general, and is practiced in the context of acquaintanceship. She chews while hanging out with guests, whereas when she’s with people in her close ingroup, she’s much more inclined to relax or sleep. So the question is: Does she love to chew socially because it’s an outlet for her excess excitement, or is it a social performance?
