Shouldn't this be in the pet forum?

MoCo has two paths you can take. There is a number to call if the dog is actively barking and they send an animal control car right away. Or you call a different number and lodge a complaint that the county then follows up on. Seems the first is the better option if you want to guarantee that the county sees the situation underway.

Avoid what fees? I'm reasonably presuming that if one lives in CC, one is not concerned with fees.

I would buy this: Dog Barking Controller

Stop your own dog's barking without harsh discipline; stop a neighbor's dog from up to 50 ft. away. Easy trigger action releases a high-frequency sound audible to dogs which can also help train without harm. Effective with cats, too. Uses one 9V battery (not included).
