I work for the Humane Rescue Alliance. Debbie Duel, our DC-based Director of Humane Education, gave the following recommendations. Some have already shown up in this thread:
May I Pet Your Dog?: The How-to Guide for Kids Meeting Dogs (and Dogs Meeting Kids) Hardcover – Illustrated, April 16, 2007
Don't Lick the Dog: Making Friends with Dogs Paperback – March 26, 2022
Tails Are Not for Pulling (Board Book) (Best Behavior Series) Board book – September 15, 2005
Hot Dog: (Winner of the 2023 Caldecott Medal) by Doug Salati | May 24, 2022 *** Not a traditional safety around dogs book, but a lot of fun to read and talk about out loud. If I had a kindergarten or 1st grade class, I'd definitely try to build a safety lesson (for dogs and people) around this book.
