Puppy Room Temperature Chart
| Puppy Age | Room Temperature | Notes |
|---|---|---|
| 0–4 days | 85–90°F (29–32°C) | Critical newborn period. Keep the area warm, dry, and draft-free. |
| 5–7 days | 80–85°F (27–29°C) | Puppies are still very sensitive to cold. Maintain steady warmth. |
| 1–2 weeks | 75–80°F (24–27°C) | Puppies begin moving more but still need a comfortably warm environment. |
| 3–4 weeks | 72–75°F (22–24°C) | Begin gradual reduction as puppies gain better temperature control. |
| 5+ weeks | 68–72°F (20–22°C) | Most puppies can handle normal room temperatures at this stage. |
Setup Tips for Success
-
Use a reliable thermometer.
Place it at puppy level, away from exterior walls and direct heat sources. -
Provide a warm zone, not just a hot room.
Heat mats or lamps should allow puppies to move away if they get too warm. -
Keep the area draft-free and dry.
Avoid fans, cold floors, and direct A/C vents near the litter. -
Monitor humidity.
A moderate humidity range can help keep puppies comfortable and bedding from becoming too damp or too dry. -
Change bedding regularly.
Warmth and cleanliness both matter in the whelping area.
Watch Your Puppies
Signs Puppies May Be Too Cold
- Crying or frequent whining
- Huddling or piling tightly together
- Cool to the touch
- Lethargic or sluggish behavior
Signs Puppies May Be Too Warm
- Panting
- Spreading away from one another
- Moving away from the heat source
- Restlessness
The thermometer matters, but behavior matters too. If the puppies look uncomfortable, adjust the environment and recheck the room.
Why This Matters
During the first few weeks of life, puppies depend on their environment for warmth. A room that is too cold can increase stress and risk, while a room that is too warm can also make puppies uncomfortable. A simple age-based guide helps breeders make better day-to-day decisions in the whelping room.
For New Litters
Use the warmer ranges during the first days after birth when puppies are most vulnerable.
