A dog that went missing during the floods in Central Texas earlier this month was found alive with help from a trackable GPS collar.

The deadly flooding over the Fourth of July weekend killed at least 135 people, including dozens of girls at Camp Mystic, along the Guadalupe River, according to officials. Officials in hard-hit Kerr County had said the number of people believed to be missing was more than 100, a figure they later revised down to three.

Over the weekend, officials in Texas announced that the number of people missing after the July 4 floods had dropped from over 100 to 3.
