Why do dogs bark?

[OAITW r.2.0]

Skippa, my GR. goes out at nights and sometimes I never him him. Other times, like, tonight, he is barking up a storm. Rural property. no harm, no foul. But why?

1. He smells something.

Do you have wolves or coyotes around? Any deer?

2. Deer, for sure. I expect to hear coyotes packing up and howling at the moon, soon.

3. Probably hears something that you aren't able to discern?

4. That and smell. He's way ahead of me on those senses.

5. Yup smell too.

Pretty sure my Pittie would suffer an anxiety attack if he knew alpha's hearing & sense of smell is so deficient.

6. Confused, happy, afraid? Don't let him watch the news any more.

Worry when he doesn't bark.

7. Maybe Kristi Noem is lurking about?
