I just bought my dog Lincoln, now 12 weeks old, an exercise pen for inside the house. My house is big and I struggled to try and keep an eye on him making sure he wasn't getting into things he shouldn't and having accidents throughout the house. So i bought him a good size playpen for the house. He does fairly well and its still adjusting but I need a couple of opinions. He seems to do well when we aren't walking by it too much but once he sees us he goes on a barking spree (granted it doesn't last too long) should I put his pen somewhere we aren't walking by it so often? Or should he get used to seeing us pass by? Also, what do you guys think about putting the pen in the backyard every now and then for an hour or so? TIA!
