Looks like there are some really great ideas among these posts! Cyclone fenced, double gated, water, shade and cleanup tools!
In Auburn Hills there is a large County park with a Doggie park set aside. I think there is about 15 acres, mostly mosquito infested! There are lots of woods, some bog area around the lake, various levels of terrain, and semi-groomed trails (gravel in the wet areas - chipped wood mulch in dry areas) There is a drive-in fenced area for about 10 cars. Normally that is more space than is necessary, as there are probably only 3 to 5 cars at any given time. However, Saturday mornings seem to be the biggest drawing for the Doggie Park, and then I've seen cars parked on the side of the 55 mph 2 lane blacktop road. This could be rather dangerous if people and dogs were entering and exiting on the road side.
The whole doggie park has lots of pluses. The minus' are mostly the owners and the dogs that don't play nice, or are totally uncontrolable. I think that is pretty normal of most of the DPks. It would be nice if all the people that used the parks would remember that just like humans, some dogs are bullies, some passive, and most are like Cindy Lauper.."Just Want To Have Fun!"
Great response everyone! Maybe more cities and counties need to consult more owners before building the DPk!
