The event will be from 7 a.m. to 7 p.m. Saturday, Aug. 11, and Sunday, Aug. 12, at 1403 E. Washington, Union Gap.
The goal is to place more than 200 pets in loving homes, and Benton County Animal Control in Kennewick also is among the groups participating.
According to organizers, this event will feature mostly dogs, but there also will be some cats ready for adoption.
Never miss a local story.
Fees will vary, but all adoptions include a spay/neuter, vaccinations and de-worming. Most of the dogs and all of the cats will be micro-chipped.
There will be a number of coupons and giveaways throughout the weekend.
