imo the risk is outweighed by the benefit. An hour ago victor was climbing the walls..the weather was perfect, he knew it, and he knew i knew it. A good hard run like that cannot be obtained one an acre. Now he is sacked out on the bed, Pepper had a rock on lesson for bootcamp goes on the road, and Mary is sappy happy. THat would not have happened if i hadn't taken them there. It would take a horse and rider to give Victor the exercise he "thinks" he needs. Pepper is half as bad. There is a responsibility to having a dog like Victor, and dog parks are about the only outlet a lot of people have. I watch the basinji across the street that is on a tie out. HE is well cared for in every other respect but one. They never walk him, he doesnt' even have a fence so he runs in little circles like any other cage crazy animal. WE need dog parks for hard driving dogs. Maybe it isn't for a lot of breeds, maybe they don't need it worse then food and air to breathe like Victor does. I know only that i am grateful that such places exist and get him to one park or another every chance we get. He's never gotten sick, or been in a fight, there were two mastiffs that tried to hunt him down, but we just left to a different part of the park. OUrs is 55 acres and that is alot of room for everyone.
