pup begun his walks a couple of days ago and loves them! he keeps bursting into an attempted run though and I would love to let him offlead. There's a great enclosed park nearby where dog walkers seem to gather. When and how soon should he be permitted offlead? i find the prospect quite scary! What if he runs off? Or another dog goes for him? The walkers arecall a lovely bunch with lovely well behaved digs hut.......
