At Le Thi Lan's pho shop in Cu Chi district, Vietnam, there is a dog named Lucky that she has raised for more than 10 months.
The dog was donated by Lan's neighbor. Although not trained, Lucky dog ​​is still very intelligent.
When a customer buys Pho, the dog automatically runs out of the house to get money from the customer. The dog can distinguish two types of money in Vietnam: paper money and polymer money.
When the neighbor tried to play with the polymer money and tissue, the dog only took the money, not the tissue.
The dog was given beef and beef balls by Ms. Lan as a reward for him.

Interview Mrs. Le Thi Lan – Dog owner:
From a young age, I told him to pick up something, he would run to pick up the exact same thing. I told him to collect money from the sale, he also ran to collect money himself, not teaching anything. Neighbors love it and come to play with it.
Whoever hits me, it will immediately run back to intervene, when I go to sleep, the dog will often lie next to me, when I sleep, it will sleep, wherever I go, the dog will follow. Lucky is afraid to go to the street because the container truck runs continuously.
In particular, when he was full, Lucky stopped working but stayed still, no matter how he called out, he still wouldn't budge.
Someone paid me a very high price to bring Lucky, but I refused because this dog is a family member, no matter what I can't leave Lucky
