WASHOUGAL — Double-up those leashes. A dogfight in a Washougal industrial park has reached the breaking point.

The West Columbia Gorge Humane Society says the owner of a neighboring company, Northwest Underwater Construction, has been harassing its animals and volunteers as part of an ongoing noise dispute. The two entities are located within the Port of Camas-Washougal Industrial Park.

Last fall, the neighbors traded accusations about noise levels at the shelter: The construction company alleged that the constant barking emanating from the shelter’s kennels was a nuisance; the no-kill shelter countered that a high-pitched siren the company installed atop a fence separating the properties, meant to quell the barks, disturbed the dogs.

Washougal finally intervened, spending $8,000 to build a sound-dampening wall between the properties. The city owns the Humane Society’s property and leases it to the shelter for $1 a year.

In the ensuing months, the barks haven’t been silenced. Neither has the dispute. The owner of Northwest Underwater Construction, Jesse Hutton, routinely drives his Humvee across the street from the shelter so he can videotape the kennel.
