This is a great dog park on the west side of Vegas. We've been bringing our husky, Buddy, here for a few months now. We used to go to a dog park closer to home, but once we found this park we never went back. We're willing to drive further for the nicer facilities here.
It's conveniently located right off of Summerlin Pkwy. There's 3 very large enclosed dog runs; One for small dogs, one for large dogs, and it appears the last is rotated and closed off to cultivate the grass. There are multiple covered seating areas with concrete benches, lots of shady trees, and the grounds are completely covered with grass.
We've come here at many times of day. By far there are the most dogs out to socialize at sunset when the temperatures drop a little but while there's still some light to see. Last night (which was an August Sunday) we came here around 7:30 PM and there were 40-45 dogs with owners hanging out in lawn chairs and blankets. Alternately, we have come here Saturday and Sunday mornings to usually find about 2-10 dogs in the large dog run. It seems that Sunday evening is the time to go if you want to get the most socialization opportunities for your furry friend.
