Oh hunni I know they need tons of exercise. She won't be in there 24 hours a day. I'm thinking just like off and on like 2hrs total max (outside time while I go run errands) or during the nights some if its warm out.

I wouldn't leave either of my huskies alone in there for more than 15 mins tops, ESPECIALLY unsupervised. That's just asking for trouble or an escape. To Koda, that would be a fun toy momma gave him to see how quickly he could escape from it.

An unbolted, unsecured pen like that wouldn't hold him for more than 2 seconds if he decided he wanted out (saw a squirrel, bird, cat, dog, or just got bored).

I would be very wary leaving your puppy or even adult dog in something like that while unattended especially if you're leaving the premises. My initial thought would be someone would swipe him or let him out and my dogs could knock that over or do something to it to get out fairly quickly. The safest place for your dog while you are busy and especially if you aren't home in the crate inside the house.

i'd be really nervous about it getting knocked over by her, I can't image it would be too difficult. My worst fear is mine being stolen, so I never, never leave them outside unsupervised.
