This dog park is great for BIG and small pups! Located passed the railroad tracks on 18th St, just under the Birmingham Bridge.
The park is split into two sections, big pups and little pups (under 25lbs) which is great because my boyfriend and I have a chihuahua that is normally afraid of big dogs, so it's nice to be able to let her loose in the small dog section and her not be afraid or timid around the other pups. It is well equipped with benches and great landscaping, and has an amazing view of the river. A great way to spend an afternoon chillin with your favorite doggies! The park has a nice amount of trash cans, it may seem odd that I mention this but the dog park at Olympia Park on Mt. Washington is about 3X the size with no trash cans for doggie waste.
Only negative thing I would have to mention is this park can get pretty muddy! Especially near the entrances/exits. Don't go right after the rain!
