Our newly adopted 2 year old Standard Poodle is very well mannered, VERY curious, absolutely housetrained despite being raised in a household with way too many dogs. They apparently did not either "play" with him or walk him. Once he gets done with some "sniffing" he walks almost perfectly, but, has yet to urinate on leash. We've had him for a little over a week and my daughter had him for two weeks. He has been walked, sometimes long walks, at last once daily. No urination for our daughter or us. This, if it continues, could be a problem as we plan on camping with him. Suggestions?
