I had been coming to this park for a few years. It was a nice place to go, it has a small agility course, water and a separate area for small dogs.
The dog owners at this park are a mix between competent and down right rude.
My husband was nipped by a small dog in the big dog area while crouching down. He turned around to shoo the dog away and the dog's owner came up and started beating her dog right in front of us. She was confronted about it by us and several people in the park, and she left.
We have run in to several aggressive dogs, and a lot of people bring non-neutered/spayed dogs to the park.
My WORST experience was with a city employee coming in to clean up the garbage. My weim came to the gate as he was coming in and nudged his hand...he started screaming and swearing at me that he was going to kick my dog if I didn't get it out of the way. There were 2 witnesses with me that saw what happened. He claimed my dog bit him on the hand through leather gloves (she has no teeth). He got directly in my face and screamed at me. This guy was pretty big, and I am female. If my dogs were going to attack him, they would have done it when he was in my face being aggressive..go figure. The police got involved and I contacted his managers. They didn't really seem to care a whole lot and told me I was wrong to think that employees working in the park should be used to being around dogs, and should know the difference between a nose nudge and a bite.
Hate this park. Still go because it is the only one close to us, but I will NEVER GO ALONE again. I also carry a camera capable of video when I go now.

Are the other parks you talk about off leash parks??

EDITOR COMMENT: The parks discussed here are also legal off leash parks. I had added links, just click on the name of the park and it will take you to that dog park page.

Have you checked out Chatfield Reservoir? They have a lake for the dogs to swim. My lab loves it. You do have to get an annual State Park pass, but that will get you into both Chatfield and Cherry Creek, which both have good dog parks.

Try Cherry Creek Dog Park, it's my dog's favorite!

Moving from Houston area to Denver...The BEST Dog Park in Houston is Millie Bush Bark Park in West Harris Co...LOVE it..15 acres, fenced, two swim ponds, area for small dogs...Wanting to find similar in Denver area..my 4 friends (yes FOUR!) are HOPING Daddy finds them a new playground equal to the one they have been at..any comments would be helpful!

We have been here a few times. Most everyone is considerate, but of course you are going to find the occasional person that doesn't pick up after their dog. Overall a great place to take your dogs!!

Parks need more people like you, at least someone cares about other peoples feelings. You hear that world there is someone out there that cares

Lately I started cleaning up the dog poop myself on every Saturday morning. Hopefully people will follow my example. I'm not trying to blow my horn, just trying to keep the place enjoyable and clean.

I take my dogs here frequently but have noticed many dog owners are very lazy when it comes to picking up the doggie droppings lately. Filling up poop bags and giving them to the "offending" dog owners helps some but not enough.
The dirt is now everywhere but this place used to be all grass believe it or not. The obstacle course is a nice touch and the trees and fire hydrants are a winner. The summer only water pump is great, too. It's still a good social hangout for owners and their dogs.

This park has some good points... It has a separate area for small dogs, and it has some obstacle course equipment... The downsides... It's almost all dirt (very little grassy area); parking is far away from the fenced area; people do not clean up after their dogs much and there is ALOT of poop EVERYWHERE. There are mch nicer parks in the area to bring your dog to.
