I'm curious to know how different people knew when their pup was ready to go off-lead in the park etc. Richo is now 9months old and we've just started having one of us leave the house (opening/closing the front door) with him just sitting inside and not on a lead. We know that he has no intention of 'escaping' - he would simply want to follow us out of curiosity - but I am sure that once outside, distractions would prevail and he'd be off on a big adventure. Is it simply a matter of being confident in the 'come here' command? Just knowing that wherever you were, and if he was at the end of a long lead, or a run, that a simple call would have him return? Where are the places that are best for testing this?
