Second trimester

Baby gates, a dog retreat zone, shift routines, start daily special time.

Third trimester

Baby sounds at low volume, lotions and smells, stroller walks, a care plan for the hospital stay.

Quick answers

When should I start preparing my dog for a baby?

As early as possible. Many steps work best 4+ months before the due date, but every step helps.

How do I get my dog used to a baby?

Introduce baby sounds, smells, gear and new routines gradually during pregnancy, and reward calm behavior.

Do I need a trainer to prepare my dog for a baby?

Not always. If your dog has growled, snapped or bitten, or guards things, work with a certified professional.
