55First time as a Sniffspot guest and it couldn’t have been better! The area was HUGE. There was so much space for my fur baby to run and sniff, along with some shaded areas. Instructions on where to park and the entrance for the spot were clear and Kristie was very pleasant :) Will be coming back soon! Lani B.

55Had a great time! The host even had a dog pool and water drinking buckets ready for the hot day. The area is on a hill good for tiring your dog if they don't have mobility issues. Shade covers the bottom side of the area. My dogs loved the odd shaped tree branch at the fence.Saba X.

55would recommend going on a much cooler day as it gets hot there very quickly but wow there's so much space to run around in and they provided buckets of water, a pool, poop bags, there's also about 3 chairs for ppl to sit. Will definitely come back on a cooler day/time Jasmine A.

55What a dream for my pups and I! So much room to play and sniff. It was a pretty hot day so they didn’t run as much as they usually do - but that just meant I had a chance to relax.
Kristie was super communicative and even allowed me to bring ok a back to back slot since I drove about 55 minutes to get there.
Highly recommend and will 100% be back. Lynda G.

55We've visited twice now, and think it's a lovely spot. There is much room to run around, plenty of water, and of course, lots to sniff. Kristie is also a very nice and communicative host.
There are a couple of chickens visible and we have heard the neighbors' dogs barking once. We think these are great opportunities for our dog Walnut to learn.
I would highly recommend this sniff spot. Josue R.

55This was our first visit to a Sniff Spot. My dog definitely enjoyed lots of sniffing and exploring. The perimeter had nice shade. We went mid-day in July so it was pretty hot, but there was plenty of water and shady areas. In the future if I go in summer I would go earlier or in the evening to avoid the heat. The owners were very nice and helpful. It was nice to get away from the concrete jungle. Christa L.

FAQ about our Castro Valley 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 Castro Valley area range from $4.0 and $4.0. The least expensive dog field is Cozy Yard Friendly Owner near Greenwood. The most expensive dog field is Cozy Yard Friendly Owner near Greenwood. Each host sets their own price, so you can check the price on the specific Sniffspot dog park listing.
