Itzi slipped passed me a couple of days ago when I was letting Blossom outside to do her business, and I didn't know it.(Itzi was with the pup about 15 minutes) When Blossom and I came back in we found Itzi in with the pup. Blossom had a fit.
I got Itzi out of the situation, and she still lays by my bedroom door and cries. So her getting to be by the pup didn't help. I appreciate those suggestions though.
