Anxiety the most when alone Will escape fence, kennels with a person or without outside with him--He is superfast. even known to jump out windows right through the screen--only has done this while alone Very cautious with little kids. I recommend no young kids. known to snip at my 2 year old,even while he is playing alone, crawling he snips at his butt and toes. Never hard enough to scare him or make him cry, however he does it and hasn't always done it. Known to cry alot
