Familiarity has disappeared
New smells, sounds, people, and sleeping arrangements can make rest difficult even for a normally confident dog.
Keep the night simple
Use a nearby predictable sleeping area, a calm toilet routine, low light, and minimal play. Respond to needs without turning waking into a party.
Expect gradual change
Some dogs settle quickly; others need several nights. Look for shorter waking periods and easier return to rest.
What to avoid
Keep the response gentle.
Avoid leaving a panicking puppy to escalate for long periods in the name of training.
Safety boundary
When to get more help.
Repeated vomiting, diarrhea, breathing difficulty, pain, or severe unrelenting distress requires veterinary advice.
