What happens to animals when they end up in the animal shelter?

It depends on where the pound is and its reputation. Sometimes dogs are held for a few days and if no one claims them, they're killed. Often, if the pound is already full, they'll take in dogs and kill them immediately. Some will allow dogs to be taken by rescue groups. And some, rarely, are no-kill.

Millions of dogs are killed every year in shelters and pounds. Encourage people you know to adopt dogs from shelters or rescue groups instead of buying puppies. Save a life.
