We have 2 dogs and they are only allowed in the nursery with supervision (mostly because my pug used to secretly pee in there once in a while when it was a guest bedroom). They love to come in and "help" me when I am organizing, assembling, or decorating.

The only problem we have right now is that going along with my "jungle babies" bedding we have lots of jungle stuffed animals in there, including a 5' tall giraffe. My larger dog tries to dismantle the giraffe every once in a while and there is also a parrot that she tries to pull apart, but they act really nice when they are in there and they like to sniff all of the babies new things.
