55I brought a rescue dog that I was transporting from Washington to Denver here after two long days in the car and before dropping him off at his new shelter. George was incredibly hospitable and very welcoming to us, checking in with us to ensure we were good. There are many smaller and secure areas for your dog to play and sniff in if the acerage is too much for your dog, but our rescue LOVED the space. The fencing was secure enough for our pup, and he was able to run and sniff to his heart's content. There was water available and the views were amazing. If I lived in the area, this would be a go to spot for me and my own pooch, for sure. Amy P.

55This was the perfect spot for our dog. She was able to run, jump and be free off leash in an area that was protected with secure fencing. The hosts were lovely and accommodating. We look forward to going back. Christine C.

55“Dogs Run Free” is the perfect name for this spot. My pups had an amazing time running around all of the beautiful open space. If your dog likes to sniff like mine does, they’ll be in heaven here with so many interesting things to smell! For the humans, the view of the mountains was wonderful today from this spot. George was a wonderful host as well and I’m so thankful to him for sharing this fantastic space with us. Celeste M.

55George was a great host. The property has such a beautiful view of Longs Peak and is fully fenced with smaller areas fenced in as well. There is also water available for the dogs. They had a blast sniffing and running, we will definitely take them here again! Mersaides M.

55This is a beautiful spot with plenty of room for the dogs to run. My dogs loved the space and the smells. They had a great time. George was also very nice and very helpful. I would recommend this spot. It is also good to know if you have a smaller dog that there are some spaces where they can sneak through the wire fence, so you need to know that they have good recall. But also, there’s nothing dangerous on the other side of the fence, just neighbors’ fields, and my dog and my puppy ultimately came back safely when I called. Jennifer W.

55Awesome spot to take the dogs! They had so much fun running around and exploring the pasture. A determined dog can make it through certain sections of the barb wire (mine went under once to try to get a prairie dog, but came right back). Just keep this in mind if you have a high prey drive dog. Overall, this was a wonderful spot to let my dogs get their zooms outAlexa V.

55Loved this spot! George is a fantastic host. He greeted us and gave a rundown of his property. Our 9 month old border collie had the time of his life running free! We will definitely be returning. Martha B.

55George was great! Very helpful and really allowed full access in his backyard, between letting the dogs interact with his chickens and getting exposure, to have multiple different areas for the dogs to have fun in. Even when I arrived late he late me stay later than the time. I will definitely be returning!Kate M.

55George’s space was lovely! Our dogs had a blast running around and sniffing. There is lots of room to explore, and options for smaller fenced areas too if you want a little less space. The pasture is well maintained and secure. You do walk past contained chickens on the way to the pasture, but this was not any issue. It was quite nice to let the dogs see them! There is water on site as well. George was very welcoming and the views were stunning! Alexis A.

55If your dog wants to escape, they can! Make sure your dog will come when called. Great property, kind people! There's a stretch of the fence that doesn't have chicken wire along it, so escape is easy. BUT it's not the property owner's fault my dog doesn't have great recall yet, so 5/5 rating! I'm going to get a shock collar to see if that'll deter my dog from escaping through the fence, then I'll be back! Jordan I.

FAQ about our Milliken dog fields
Are dog fields safe?
If you are looking for an adventure, but also looking for safety, Sniffspot dog fields are a great option. While public dog parks have a number of safety issues, such as aggressive dogs, distracted dog owners, disease transmission and general cleanliness, Sniffspot dog parks are much safer than public dog parks. With Sniffspot all bookings are private space for just you and doggy friends you bring with you and we require all dogs to be vaccinated (or have equivalent titers). Especially for training, privacy is ideal. Contrary to public dog parks, all Sniffspot locations are vetted and reviewed by guests so you can find the perfect place for you and your dog for off leash exercise or outdoor training. 93% of reviews on Sniffspot visits are 5 stars, while public dog parks often do not even have verified reviews. All payment is done securely online by credit card in a few simple clicks.
All park rental information is available online. Start by filtering parks by fencing, size and distractions, to find a private spot that works for your dog. If your dog has poor recall, you can visit one of our secure fields. If your dog is reactive to other dogs, you can visit one of our dog fields where there are no dogs audible or visible nearby. You can review the details of the listing to make sure it works as your desired activity space, for example, safe dog exercise, dog training, a stress-free adventure with your furry friend or even a puppy event. You can even check the park amenities chart for amenities such as indoor training facilities, agility field, synthetic turf, exercise balls or field parking availability in advance. If inclement weather is an issue or poor field conditions, you can reschedule your visit up to 2 hours in advance.
What are the requirements to bring my dog to a Sniffspot dog field?
We require that all four-legged friends have basic vaccinations or equivalent titers. We do not allow dogs with a bite history. We require that guests sign our waiver and agree to follow our safety rules. Make sure to check host rules before visiting to ensure, for instance, that you are following allowable sports activities rules and any special events rules.
Will there be other dogs at the Sniffspot field at the same time as me?
No. Facility rentals are for private play time and any host dogs are required to be kept away from the area during visits, so this is perfect for a private adventure for you and your doggie friends, and perhaps a human friend. Hosts understand that many guests have dogs in training and are nervous owners. So when you book a Sniffspot dog field you have the entire private spot to yourself. We also enforce 30 min time buffers between time slots so you will not run into other guest dogs or a previous person when coming or leaving in the field parking area. Some hosts may have multiple fields, but there is always a buffer between fields.
How much do Sniffspot fields cost?
Dog fields in the Milliken area range from $10.0 and $10.0. The least expensive dog field is Big yard, lots of smells. The most expensive dog field is Big yard, lots of smells. Each host sets their own price, so you can check the price on the specific Sniffspot dog park listing.
