Cecil the dog didn't give his owners any trouble - until he ate the $4.000 they needed to pay the groomer.
A retriever-poodle mix from Pennsylvania in the US became popular on the Internet after chewing through an envelope full of money.
Clayton and Kerry Lowe managed to glue most of the torn bills together after Cecil threw up and threw up most of what he had eaten.
The dog is big enough that, luckily, nothing happened to him.
