For months the family dog had it figured out. The baby could sit. The baby could crawl a little. The baby mostly stayed where you put her. Then she stood up.

A mom shared a short video this week that captures the exact moment her dog realized the rules had changed. Her little girl is toddling around the house with that wobbly first-steps swagger. In the background stands the dog, frozen, wearing the face of someone who just saw a ghost walk through the kitchen.

The words over the clip set the scene. The baby suddenly starts walking and the dog is terrified.

Room to room with nowhere to run

What follows plays out like a slow-motion chase scene. The baby heads for the dog. The dog politely backs away. The baby turns the corner after him. The dog relocates again. No matter which room he picks she eventually comes waddling through the door with a big grin.

His mom summed it up in her caption. His peace ended the day she took her first steps.

Viewers feel his pain

People watching could not stop laughing at how betrayed he looked. One viewer said the poor dog thought he had a few more months before the chase scenes started. Another spotted the moment the baby got near the stairs and said you could practically hear him yelling for his mom.

Anyone who has raised a baby with a pet at home knows this stage well. Crawling is cute. Walking means a tiny new roommate who can suddenly reach your bed, your toys and your tail.

The good news is that most dogs make peace with it soon. Give it a year and these two will probably be partners in crime splitting snacks dropped from a high chair. For now the dog is simply grieving the quiet days. We wish him a good nap while he can still get one.
