Anna Faris Coughs Up $5k in Lost Chihuahua Caper

Anna Faris paid thousands of bucks as a penalty for giving the family dog away.

Anna sent a $5,000 check to Kinder4Rescue earlier this month for giving away Pete the Chihuahua she shared with hubby Chris Pratt ... without notifying the rescue org.

Pete apparently escaped or was thrown out of his adoptive home and surfaced on the streets looking like skin and bones.

A microchip led Kinder4Rescue back to Anna, and the org demanded the $5k penalty she agreed to pay if she gave the dog away without prior notification.

Pete's still hangin' at Kinder4Rescue ... in search of a new home.
