My 2 older ones get free reign. But since we got the puppy a few weeks ago, I've been gating off the upstairs & leaving the puppy in her expen. The other 2 stay downstairs so she won't be lonely. Although, she's almost graduated to free reign. I've left her downstairs with the other 2 twice for about 15 minutes & she was unharmed and no puddles when I got home

She'll be 5 months on July 5th.
