Most introductions between pets fail before the two animals ever actually meet, not because anyone did anything wrong, but because everyone in the house wanted it to be over quickly.

If you're bringing a new dog or cat into a home that already has an animal in it, you've probably already found the standard advice: meet on neutral ground, let them sniff it out, give it a few days. That advice was written for the easiest version of the problem. This book is for the rest of us: the senior cat who's had the run of the house for years, the rescue dog with an unknown history, the household with kids and no spare room to spare.

The Slow Hello walks you through a complete, staged introduction system built on how animals actually communicate, not outdated pack theory or one-size-fits-all timelines. You'll learn how to prepare your home before the new pet arrives, read your resident pet's real stress signals, run a scent-and-barrier protocol that works for dogs, cats, and cross-species households alike, and troubleshoot the specific setbacks that stall real introductions, from redirected aggression to fixation to sudden regressions. It also tells you honestly when peaceful coexistence, not instant friendship, is the successful outcome you should be aiming for.

Practical checklists, clear warning signs, and a patient, evidence-grounded approach for every stage of the process, from the first seventy-two hours through long-term life together.
