I read recently that Huskies put the "H" in Houdini.
I beleive it.
I have a trolly between two trees in the pen, and my FIRST husky was on the trolly for 17 of his 18 years. I only let him off it very reluctantly.
Only in my fenced in dog pen in the back yard. (25' X 25'), or upstairs in my 3 level house. I also have a 15 1/2 year old Collie, and I keep them apart.
Henderson's only 14 MONTHS old, and not trained well yet.
