I have never in my life seen a puppy who at 8.5 weeks, whine or bark to go outside when they have to pee/poo.
It is amazing my husband and I how smart this puppy is. She had just barked at me, and I said "What?" she barked again. I asked "Outside?" with that she started getting all "bouncy" and ran to the patio door.
Within 10 seconds, she did #1 and then 2.
This is shocking to me. I have a savant for a pup.
