(SFGATE) — There are some things that the digital newspaper subscription on an iPad can’t do. Helping toilet-train puppies at an animal shelter is one of them.

San Francisco Animal Care & Control has been relying on public contributions and occasional Chronicle donations of old newspapers to line animal cages and catch waste from puppies who don’t know how to take their business outside yet.

But Thursday, an animal control van parked at the San Francisco Public Library was loaded with two 32-gallon recycling bins full of old newspapers from the library as part of a new program to ensure that the shelter has a consistent stream of paper.
