Cosmo Dog Park

Very nice dog park, large and always have a lot dogs for my pup to play with. Owners are great at picking up after their pets and it has a nice lake.

This place is bad new if you love your dogs. The lake has parasites and bad bacteria living in it just waiting for your dog to ingest it and get sick or die from. The dirt that our dogs roll, play and dry themselves off with is crawling with ticks and fleas. Not to mention the active mine field you walk through just to get to where you wanna go. Or the dog owners who should have taken an obedience class with there dogs just learn some manners.
The town of Gilbert should clean the lake from germs and bacteria which are harmful to our pets. Some people spend a lot of money on dogs just to come here to have them get sick or die. If your dog is mean then keep them at home. If you bring little kids then don’t be mad if they get knocked down or barked at. There are people parks for your kids. There should be a huge fine handed out right away if you don’t pick up you dogs solid waste. A ranger should be there to give them a ticket on the spot. If a dollar bill was on the ground people would bend over to pick it up. If you got a $ 500 fine for not picking up your pets waste you might not do it again.
This park has a lot of great features and I feel it would be 5 star worthy if it was better maintained. My dog drinks from lakes and rivers all the time and I have no problem letting her drink from it. But for a funded dog park I shouldn’t have to worry about the water quality she is drinking or playing in. I love my dog to bad she wont be going to Cosmo to play any more. Which sucks for me because I could just walk there from home. Make sure your dogs have all there shots, a flea/​tick collar and a friendly vet to take care of them if you decide to go. And try to ignore the dumb dog owners.

Cosmo dog park is fucking awesome. My dog loves playing there. Damn lots of dogs play there. They even have a sexy lake.

BEWARE! Keep your dogs out of the water. It is absolutely filthy had my 2 Goldens there my younger dog got a very bad urinary tract infection from the lake and my older dog got a septic infection that resulted in her Death. She just had a full checkup 1 month earlier and was very healthy. She loved to swim so decided i would take her for a nice swim. Less than a week later we were at the vets saying good bye to her. Tried the TV stations but they were no help. Have heard others have issues as well one dog got eye ulcers from the water. Do not let your dogs in the water please. I don’t you to go through what I went through.

This dog park is beautiful. It has a section for dogs that like to play in the pond, for dogs that are timid and dogs that want to do training thru obstacle course. But I have to say… it is pretty dirty. I almost step on dog poo a few times, genral grass area is dead in patches and one of my dogs came home with a cough that hasn’t gone away (I am sure it could be the weather too). Also, the pond smells very bad and it looks like no one has cleaned it for months. You can smell it from a distance away.
I was disappointed since this is one of their favorite parks. Hopefully they will clean it up soon. During the meantime, I’ll take my dogs elsewhere

Dog park is nice. The park has a pond for dogs, multiple gated areas for different sized dogs, and a small park for children. Dog owners are sometimes careless with their dogs. My pup was attacked twice in one week while owners stood and did nothing. Also, there is an exorbitant amount of dog pooh everywhere.

Ok, so I have been a dog owner for over 25 years. I have been going to Cosmos since it’s opening and my dogs name is on a brick (He died 1.5 years ago so I like to visit the brick. I recently got a new dog and began taking him there after his series of shots was complete.
I love this park and have had virtually no issues prior to this.
For the second time in a month, I have run into a very, very aggressive dog. The first experience was when my puppy who is only 6 months old and very nervous about the water, stepped in for the very first time… a rottweiler who was coming out of the water, dropped it’s ball and ran at my puppy and attacked and put him on his back IN THE WATER biting his neck! I called at my puppy calmly who was whimpering, Unilocaling and trying to get away at this point. The lady that owned the rottweiler named Honey I believe, practically fell over pulling her dog off of my puppy. I called my puppy away and got away from that dog. I was soothing him and had several other owners come up to me asking if my pup was ok and stated that this isnt the first time this has happened and that she had been told NOT to come to the park anymore. She tried to bring her Rott back to my dog to «make friends» and I told her to keep her damn dog away, that she was far too aggressive and should not subject others to that dog. She started to state that her dog was «jusst playing» REALLY? Come on! Other owners also chimed in and she finally left. Well, guess what? This morning I went again very early to avoid him having another bad experience… everything was fine for about 25 minutes when guess who arrived with Honey! This time, she tried to approach me and I told her that she and her dog should not be allowed in the park… she was holding her dog back by the collar btw… I told her I knew about other complaints and if she didnt leave I would call the ranger… which I did. She has been reported more than a few times.
Owners beware, if you see a short woman with blondish brown hair, sunglasses, wearing shorts and a tank top with wading/​rain boots and carrying a chuck-​it stick… keep your dog safe and get away and call the ranger. The number is on the sign by the gate.
ugh.

There’s a pond!!!
Now that that’s out of the way we can get down to business. This park is actually pretty nice overall, there is plenty of parking, different areas for the dog sizes and they actually have two large dog areas that they rotate to avoid overuse. Now, with that being said there are much larger dog parks in the Mesa-​Gilbert area, most notably quail run dog park. The thing that quail run does not have though is a pond which is the absolute highlight of this park, my brothers two water dogs burst through the gates and launch themselves into the pond like they were in the Olympics. My dog (who mind you has webbed feet) was much more hesitant and took about a year of water exposure before he would venture into any body of water, of course now he loves it and hardly ever wants to leave. I would absolutely recommend this park to anyone who has a high energy dog that maybe doesn’t like to play with the other dogs per say in the grassy dog park area but is a big swimmer, it will surely tire them out.
When you are leaving make sure to wash your dog down with the provided hosing area as you do not want pond water on your dogs body for a long period of time.
The only thing I would change about the pond area is some sort of circulation to keep the water moving as stale water turns gross quick.
Enjoy!

This is a great dog park. There’s lots of room and a few separate areas depending on your dogs temperament and what they want to do. The pond is great but it was pretty dirty which made me a little nervous because my dog will drink just about anything. My only gripe is that there is not much shade available, especially during the day, and I wish there was an area for the dogs to drink from other than a hose, like the water fountain at Hance park. Overall, we had a really great time here and my dog really enjoyed it.

My dog, Rowdy, had a great time at this park once he got over his fear of the water. There was one lady (whom I am told is a regular) who allows her dog to bully other dogs, without correction of any sort. It is unfortunate. We only left when we did because of this lady and her unruly dog. Other than the experience with this woman and her bully, we had a very good time.
Be aware that the water is quite dirty. Giardia (protozoa) is very prevalent in water like this. Make sure you have your dog on anti-​parasitic before taking him here and water for runny stools.
I also recommend a very good bath in the bathing area. You should probably even bring your out biodegradable (planet friendly) shampoo to make sure your dog does not bring home a bacterial or fungal infection. Or stink to high heaven and ruin your car seat. A super thirsty towel is good, too.
Owners WILL get wet. And probably dirty/​muddy also.
But it’s worth the hassle!

I have a smaller dog, and I’m upset that my dog got attacked by a bigger dog. The park is not safe at all for smaller dogs. I would like if there was a smaller area in the lake section for smaller dogs.

Updating to add a heads-​up to anyone who takes their dog to play in the pond at Cosmo. We took our dog to the vet and found out that she has Giardia, which is an intestinal parasite that is most commonly transmitted through feces contaminated water. Our dog is now taking meds and will be retested in two weeks. Our vet says she usually gets at least two cases a week from dogs that play in the pond at Cosmo. I’m still giving Cosmo 5 stars because it’s awesome, but we will be playing only on the grass side from now on. (Don’t worry… we will be keeping our dog home until she gets a clean bill of health from the vet!)

Great dog park, way too far from home to go regularly, but a great trip to beat the summer heat.
The swimming area is great to escape the Phoenix area summer time weather.

This is the largest dog park that I’m aware of in the east valley. I like the variety of play areas and how they help to group certain types of dogs to avoid conflicts. The main attraction here is the small «lake» for water loving dogs.

went here for my first time a couple weeks ago with my pug and frug and frenchie
my pug LOVED swimming in the lake with the big dogs — I’ve never had so much fun at the dog park with my babies!
the lake is not completely gated but I didn’t see any dogs swimming so far as to where they would jump out on the ungated portions. You’d want to keep an eye on your pets to make sure they don’t get to that point
it’s gated enough to where I felt safe. the lake dog park area is shared with all sizes of dogs and everyone got along great. it’s like a beach where you walk in the shallow and then it gets deeper the farther they go out.
there’s a washing station to wash off your pets when it’s time to go –wish there was more than one but the wait wasn’t bad.
you can take them to one of the normal gated dog park areas after the rinse off to dry
it’s a 40 minute drive from where I live but I’ll be back!

I’ve lived in the Valley for a little over 27 dog years, and I’ve yet to find a better dog park than this.
Why is that?
You’ve got a giant swimming pond, a diving peer, obstacles, plenty of running room, and a whole lot of other dogs.
My pooch has been enjoying this spot nearly our whole time as residents in the state of Arizona, and when I say, «Cosmo?» he perks his ears up and immediately looks toward where his leash hangs on the wall. He knows what’s up, and if you have a dog in the East Valley, so should you.
While I’d love to give this place a 5-​star rating, I just can’t. That’s not because of anything Cosmo does or doesn’t do as a dog park specifically. Rather, it’s because sometimes you’ll run into dog owners who have no idea how or desire to learn how to maintain their dogs. It can be canine chaos at times due to the sheer number of pups, grizzled vets, and human children running amok. Occasionally you’ll find someone who wants to sit on the sidelines and let their dogs run roughshod, leaving the yeoman’s work of wrangling and corralling up to the other owners, without so much as even a hand from the actual owner or handler of the offending dogs.
That being said, this is a minor quibble, and the situation arises infrequently, while it’s something you’d probably expect at any other dog park.
I have friends who live closer to downtown Phoenix where there are plenty of dog parks to enjoy, yet they still want to meet me out here in the suburb of Gilbert with their pooches to enjoy some Cosmo time.
That should tell you all you need to know.

Ok, so I live like 2 987 912 miles away from here, but I occasionally make the trip out because my dog LOVES this place. This is one of the few/​only dog parks in the PHX metro area with a lake the dogs can swim around in, and the park is huge.
Overall, great if your dog loves water.

This is the nicest dog park I have ever seen. My husband said doggie park” to my in laws dog, and she understood and got really excited before getting there. And I saw why she was so excited when we got there. This dog park has a large pond for the dogs to swim and get in to play around. There is also plenty of land for them to run around on. Owners were playing fetch with their dogs and the dogs get to roam free and have a blast chasing each other. There is also a smaller fence area for miniature dogs if you don’t wish to mix them in with the bigger dogs. After your dog is done running around there is an area to rinse them off before u leave as well. The only reason I give this place a four us because some owners didn’t pick up after their dogs and you have to be careful where you step. And the places to get poop bags were also oddly located. Otherwise a very nice doggy play time!

This is the place to go with your furry friend! they have a lake, a fire hydrant watering pool, obstacle course, a marsh, giant steps (ampitheater). this is a great park all around.

Took our pup here after searching for a dog park with a water feature. It was a Thursday at 7pm and we drove 30 minutes just to check it out.
The park looks very nice upon I eat glance. There are some gazebos dotted throughout with a lake right in the middle. There is a basketball court that was packed.
The dog was eager to join the others so we quickly went inside the gates. The gates are double gated which is nice and is not standard at all of the dog parks in the area. There were about 10 dogs inside the big dog side. There was plenty of room to gallop. There could have been many more dogs and everyone would have room. Maybe this place is too big? There was only one place for the humans to sit while inside… But you should probably be up and about kind of near your dog rather than sitting on the other side of the park right?
There was a hose with a bowl for when he got thirsty. There were a few things to climb on. He wasn’t too interested. I love how the park was made as tribute to the first K9 officer in Gilbert. That is really cool and you can really see the love that was put in to the design of the park, giant paw prints and all.
We were wishing for some more grass so that was a bummer. If it were a bit wet it would have been all mud. Interestingly enough I was anticipating lots of land mines from idiot owners who pretend they don’t notice their dog dumping but I didn’t see a single one! There were plenty of bags, but they were the grocery bag sort of bags. Hey, reduce, reuse, recycle, right? I don’t know who is stocking those but it works.
After a while we wanted to see if the dog would like the little lake since he is half newfie. There were a bunch of little dogs jumping right in. Surprisingly enough he joined them! He was having fun until he fell off the edge of the beach and into deeper water (about 6 feet out into the water it it’s drops off) and he got so freaked out he didn’t want to get back it. After a while we hosed him off and dried him. He didn’t stink too bad. Many dogs were chasing balls and diving right in. Hopefully he will too some day!
I really would appreciate the fence to be extended. He’s a great swimmer and if he ever gets back in, it really won’t take him long to swim to the side on the left where he can get out and I’ll be stuck in the park. You have to be there and see it to understand but it would be really easy to escape that way and the humans have to double back to get out the gate. I have no idea how deep it is right there and maybe he wouldn’t be able to pull himself out of the water without somewhere to plant his back feet, but since he is huge I can see him managing it.
Im a tiny bit worried about the water making him sick only because we have never done anything like this before. I will definitely update my post if he does.
Go try this park out. It’s really not too shabby! We are going to go again on a warm weekend so there are plenty of friends for our pup.
