Dogs take over the pool at the 4th annual Pooch Plunge held in Fort Collins, Colorado. City Park pool is open for the summer season and then closes for the rest of the season. Before the pool is drained our four-legged friends get to enjoy the pool. This August 19th – 20th, from 4pm to 5:30pm you could bring your pooch to the pool. $5 pre-sale, and $7 at the gate.
