Their is a male white who drives a black 4-runner. He comes to the park and owns a brown and white St. Bernard and a large black dog. The St. Bernard is well in escess of 100 lbs. The black dog is approximately 90 lbs. This man cannot or will not control his dogs. they are aggressive and attacked my dog just outside the front gate. They were also observed trying to attack (aggressively) either another man and/or his dog. A police report is on file. At this time, the people who run the dog park do not have a plan to keep out overly aggressive dogs and forbid them from returning. I think they are working on this problem but until then, we can only warn others about problem dogs and their owners. If you see this man and his dogs, you may want to exorcise caution.
