My Maltipoo puppy (10lbs) is 17 weeks and since my husband works from home he's not crated often, we have a playpen area on hardwood that we mostly use when we can't directly supervise or need to leave the house, the max I've left him in the playpen while out is 2 hrs but I'm wondering if maybe he could go longer at this age? I know in the crate he can go atleast 3 hrs with no accidents but we also have yet to crate him any longer then 3 hrs. When home we take him out about every 2 hrs and restrict his water intake. He's slept overnight with no issue from 8 weeks. Thoughts?
