Chloe the White German Shepherd Talking to Momma in the morning

Chloe always has to talk to momma in the morning. She will say "Mamma! Mamma!" when my wife3 comes home. if you listen close she says "momma" softly a couple of times. Notice that she winks at the camera at the end.... then gives a big yawn. And who says GSD's arent smart.
