Im devastated

I was going to the beach yesterday, and we went to Dollar General, and there was a beagle laying on the grass. We went inside Dollar General and asked if they knew how long the dog was there. They said about a week. My mom freaked out and said that we were going to get the dog if nobody took it. Then we went in our car and then we saw a guy that took the dog. My sister started crying and i was kinda mad but happy that the dog got a home.
