Another quiet walk on the Tangara Trail

I took a walk with my dog on the Tangara Trail at Acton Park/Roches Beach this Easter weekend. Lovely day for it - and not a a horse rider or cyclist in sight. I was out for 2 hours and covered about 6km. The weekend before I visited Acton Park and Mortimer Bay areas of the trail, a total of 4 hrs and 15km - and no cyclists or horses. On the few occasions in the past when I have seen cyclists and horses, I take control of my dog until they have passed. There is so much space for everybody. The proposed restrictions mean that I will have NOWHERE to take my dog for an off lead walk. Confining dogs to on lead walks with no options to run free and sniff is animal abuse. I drive 150km a week as it is to try and find places to take her. Why don't you just go the whole way and ban people from owning dogs altogether? How can I be a responsible and caring dog owner if I cannot provide my dog with sufficient exercise and mental stimulation?
