Just to had stop my great pyrenees 85bls (nicest dog) from eating my wife chihuahu (jerk dog) because it attack her while she was eating.
Napolean Complex is not just for humans. You should see some of the looks my rottie used to give little dogs that would run up to him at the dog park and go full on napoleon. I swear one look he gave me was, "Are you foogin kidding me, I just crapped out a pile bigger than this thing."
My smallest chihuahua is about 5.5 lbs and dominates two large pit bulls at the office.
This is Rootbeer, 80lb chocolate lab.
In the background is Daisy, a 14lb Jack Russell Terrorist......owning Rootbeers bed.
She owned every dog park she ever visited. Those dogs aint right!

Chihuahuas are 50% tremble and 50% hate.
