New puppy basics
How do I know if my puppy is anxious or just adjusting?
Last updated 23 September 2026 · How we write and check this
Short answer
A puppy that is simply adjusting eats, drinks and plays a little less than expected but gradually improves day by day, while genuine anxiety looks more like constant trembling, panting at rest, refusal to eat for more than a day, or flinching at ordinary household sounds that do not ease with time.
Ordinary adjustment moves in the right direction
A puppy quietly watching from a corner on day one but happily exploring by day three is following a typical settling curve. Small, steady improvement day to day is the key sign that this is normal adjustment rather than something more serious.
Signs that go beyond typical settling
Constant trembling that does not ease, panting while resting in a cool room, hiding for days without any improvement, or refusing all food for more than 24 hours point toward a level of stress worth discussing with your vet rather than waiting it out.
Key takeaways
- Gradual, day by day improvement is the hallmark of ordinary settling in.
- Constant trembling or resting panting that does not ease is different from typical adjustment.
- Refusing all food for more than a day warrants a call to your vet.
