dog in bushes

Question
my 13 yr old lab sticks her head in any bush she is around and just stands there like she's playing hide and seek. why?

Answer
Hey, Don,

Sorry to say I don't know exactly why your dog is exhibiting this behavior. I just know that it's not unusual for an older dog to continually get his head "stuck" in a corner, or in your dog's case, in a bush. It's an old age thing.

A vet might have an explanation, but I don't. Sorry.
