I have belonged to Treecourt Unleashed Dog Adventure since the day it opened and hope that it will always be available in the future. There have been several expansions since it opened and it only gets better. We spoil our dogs by bringing them here, but they are so much the better for having the privilege of enjoying the park and time with the other wonderful dogs. My first dog did not do well in a social environment so I had to find something else for her to do. The two that I have now, a mixed Jack Russell female and a mixed Cavalier are very well adjusted and love this park. We attend daily where we find ample water holes for drink, pools for those that love to be in water, hills to climb for more cardiac exercise and multiple areas that have been added to increase their adventurous curiosity. A small mineral water pool in the back sections is always a popular place for the dogs to take a quick jump into after running with their friends. Wayne (owner) is very diligent about keeping the vaccinations current on the dogs. The cost is only slightly over $1.00/day. I can waste more money on unnecessary things and not have the enjoyment that this park brings my four legged friends an me. I like the fact that the park is private for better control of the dogs that come in. The dogs are greeted initially and observed by Wayne to determine if a dog is socially acceptable for the members dogs. Public parks do not provide that and having been to a few public parks that can create a problem. I also like the fact that Wayne is always present for any issue that may need to be addressed. The members understand that cleaning up after their four legged friends is essential. There are numerous bags/trashcans around to allow the members easy convenience to clean up. We have a clean park as a result. Keep up the great work Wayne, members and our four legged friends!!

This is a great dog park. It is spacious with about eleven acres to let your dog run and play. There are several water stations located within the dog park as well as several park benches and picnic tables. On warm days there is a shallow pond which has cool spring water piped into it which the dogs can lie in to cool off. Treecourt has many large trees that provide a great deal of shade where you and your dog can take refuge on those warm summer days. Many members who like to walk with their dogs off leash walk the perimeter of the park as well as Horseshoe Trail which goes up a hill and has a scenic view of Simpson Lake. I like that this is a membership park and that all dogs must be current on vaccinations before they can enter. I also like that the members actively interact with their dogs or pay attention to what their dogs are doing.

The best Dog Park there could ever be! Plenty of room to run and play and because it's so big it never seems crowded no matter how many dogs are there. Wayne, the owner, a super nice guy, takes the utmost care to make sure everything runs smoothly and genuinely loves all the dogs. He lives on the property so there is always supervision. He makes sure all dogs are up to date with their vaccinations. And the property is beautiful - all the trees and grounds are well kept. And the cost to be a member is more than reasonable!

The absolute best dog park in the world! It’s my dog’s favorite place to be and there is so much room for them to wander and explore all year round.

This is a wonderful place to bring your dogs! Wayne assures that the dogs are safe by making sure that all the adult dogs are spayed/neutered and interviews and tests all dogs before he allows them to join the park. There's a great place for the dogs to get wet (2 bone shaped tubs)! My 2 dogs love it!

Incredible dog park.. No other park is like it! Wonderful to tire out your pups! Wayne is awesome! Tempers every dog.. Other lower stars on reviews are just being sore over their dog either being untrained, not well mannered, or just unsure behavior.. Trust allllll the 5 stars! All the members have been so welcoming. Love this place! Would highly recommend getting your dog in here!

We’ve been members for over 10 years and have never regretted it. Lots of space and owner is almost always on site, which makes a huge difference with dog parks. We’ve visited many all over the country. An extra attraction is the big space and the varied habitat in and near the dog park, which is adjacent to Simpson Lake county park. There are lots of birds and local resident bald eagles, herons, and egrets are often seen.

This is by far the best dog park we have ever been to. Entering for the first time, you aren’t quite sure if it ever ends. The pups can run free while you can take comfort in a discreet perimeter fence. When it’s time to cool off, there are two bone-shaped pools and a natural spring. In addition to the many features of this puppy paradise, the owner, Wayne, is one of the nicest guys you’ll meet. I swear, he is THE dog whisperer. We highly recommend Treecourt!

Large open and tree covered areas with trails. Lots of fresh water and cooling pools for the dogs. Staff is attentive and patrons friendly. Cost is more than fair.

This is a great place to let you dog run unleashed. There is lots of open space with trees and brush scattered through. My dog loves to run and he can do all he wants here. He also likes to visit all the other dogs and people. There are rules and breed restrictions. There are also benches and water stations all through the park. Restrooms No restrooms

Have been taking my two dogs, a lab and a chihuahua to Treecourt for three years. They love it and it is always a pleasant and fun experience. I've found no place better for letting your dogs run loose and socialize with other dogs that have been vetted for health and temperament. There is plenty of room for dogs to run and play or chase the ball or to just walk and get some exercise. And the dog owners that bring their pets here are a great group of people.

The real discrimination here is specifically Pits and Chows. There are pictures of other "power breeds" playing in the park. My dog isn't even a pit and I got a text saying they were canceling my meet and greet.

Max, our large yellow Lab, needs big spaces to run and roam and play in. This dog park has been a Godsend for us and for him!! He loves seeing his buddies and running and sniffing his way around every single area of the park. It's great for us to get in some good walks as well!

We tried to.take our dogs to this "dog park". It looks like a dump right off the bat. The owner was afraid of our dogs. They are 6 month old puppies and were reacting to the aggressive dogs at the gate, which he did nothing about. He told us one of our dogs wouldnt be allowed since hes a pit mix. Guess what buddy, they're brothers but don't look alike. He based judgement only on what he sees. I've never heard of a "power breed" before. Sounds lile something he made up. He also wanted shot records and for the dogs to be neutered. The guy is also kinda creepy. We'll never go back and recommend keeping your dogs far away from this place.

This is simply the best Dog Park in St. Louis. The best dog park I've ever been to period. So beautiful and such a relaxing way to begin the weekend day, or end your work day. I bring two Aussies here and they have always had such a fun time. The owner of the land and the park Wayne screens for aggressive/ problematic dogs and dog breeds as such our beloved, sweet, dogs have never been attacked or threatened. He is always happy to see his members and we are more than happy to pay what he asks for access to his beautiful property that he has turned into a gorgeous dog park.

Best Dog Park in St. Louis! Besides being huge and fenced in, the land has areas for hiking, swimming, and open field play for dogs. The owner Wayne is a genuine, friendly person who truly cares for the dogs and owners. My bulldog Dexter gets to interact with different dogs in a safe and fun environment. Also: DOG PARKS ARE NOT FREE. The amenities and space that this dog park offers is more than worth the monthly, quarterly, or yearly fee. The fee is not "greedy," it is simply paying for a service.

This place is enormous compared to the other dog parks in St. Louis, and all of it is off-leash. Dogs are carefully vetted before being accepted as members, so there is minimal problems with aggression. Going here multiple times a week is the highlight of our dog's life!

It's by far the best dog park in the area. Over 8 gorgeous acres of open play areas (expansion in progress!), 95% of which are well-manicured grass lawns with lots of shade trees, surrounded by a maintained walking trail for human exercise, benches and picnic tables where owners can rest and enjoy each other. 3 lovely spring-fed dog pools with easy access for all sizes and a beautiful hand-crafted pond circulate clean, ice cold water so dogs never overheat or play in dirty water. There are also water pumps throughout the park with bowls for fresh drinking water all year long. Best of all, Treecourt is a vetted dog park and dogs must pass muster as vaccinated, safe and friendly before they are admitted byTreecourt's experienced and knowledgeable owner. As there are dogs of all sizes and ages, if after a period of adjustment, a dog continues to play too aggressively and members complain, Wayne will ask the owner to seek further training for it before seeking reentry to the park. (Generally a dog is allowed three strikes.) This is to insure the dog park is a low-key, peaceful, fun and safe experience for all. Without a lot of heavy handed "rules", Treecourt is a caring community of responsible dog owners who monitor their dog's health and behavior so that everyone -- dogs included--can freely enjoy all its great green areas! A natural oasis. Can't recommend it more highly.

My Absolute Favorite Dog Park ⭐️⭐️⭐️⭐️⭐️ This members-only dog park is my absolute favorite, and I'd give it five stars every time! I love that it offers a huge open space for my dog to run, but also has wooded areas for sniffing and exploring. The walking trail/loop is a key feature that keeps us both moving and active. The fantastic variety of terrain makes every visit fun and guarantees that we both leave happy!
