us dog owners (any breed we have) must respect other users of the park ie runners, young familys, walkers, bikers, other dog owners, horse riders, etc. we must be in control of our dogs at all times. the park is there for all of us to enjoy in the right manner. as a dog trainer and walker i see good and bad in some owners. when i am walking a pack of dogs in the park that i trust and can control i have other dog owners with there dog come to me so there dog can play get involved with my pack. not understanding those dogs are bonded with me and see me as pack leader and the out sider is not on the list. in my view if you recall your dog and it dont come back the first time round keep the dog on the lead and do some recall training with him or her. my dogs and i are not perfect so a go back to the basics myself.
