⚠️ Not veterinary advice
⚠️ This is not veterinary advice. This content is for educational purposes only. Always consult your rescue coordinator and a licensed veterinarian before making medical decisions for a foster pet. The “call your rescue coordinator” guidance throughout this resource is a decision-support tool — it does not replace professional veterinary judgment.
For fosters raising puppies — what’s normal, when to watch, and when to act.
Foster triage tool
What's going on with your puppy?
Answer two questions and you'll get the one thing you actually need: is this normal, do you watch it, or do you call right now.
Not veterinary advice. This tool helps you decide how fast to act. It does not diagnose. When in doubt, call your rescue.

Quick Vitals Reference
| Age | Normal | 🟡 Monitor | 🔴 Needs Vet — Call your rescue |
|---|---|---|---|
Newborn (0–1 wk) | 95–99°F (35–37°C) | Below 94°F or above 100°F | Below 92°F or above 101°F |
2–4 weeks | 97–100°F (36–38°C) | Below 96°F or above 101°F | Below 94°F or above 102.5°F |
4–8 weeks | 99–101.5°F (37–38.6°C) | Below 98°F or above 102°F | Below 96°F or above 103°F |
8+ weeks | 100–102.5°F (38–39°C) | Below 99°F or above 103°F | Below 97°F or above 104°F |
How to take a puppy’s temperature:
- Use a digital rectal thermometer (baby section at any pharmacy — about $10).
- Lubricate the tip with petroleum jelly or KY jelly.
- Insert gently about ½ inch — hold the puppy still, get the reading, done in 10 seconds.
- Clean the thermometer with rubbing alcohol after each use.
- Never use a glass/mercury thermometer. Digital only.
| Age | Normal Range |
|---|---|
Newborn (0–1 wk) | 120–200 bpm |
2–4 weeks | 140–220 bpm |
4–8 weeks | 120–180 bpm |
8+ weeks | 100–160 bpm |
How to check: Place your hand on the puppy’s left chest behind the elbow. Count beats for 15 seconds, multiply by 4.
| Age | Normal Range |
|---|---|
Newborn | 15–35 bpm |
2–8 weeks | 15–30 bpm |
8+ weeks | 15–30 bpm |
Note: Puppies breathe faster when warm, excited, or right after eating. Count when they’re resting.
Lift the lip and look at the gums — this is one of the fastest ways to spot trouble.
| Gum Color | What It Means |
|---|---|
🟢 Bubblegum pink | Normal, good circulation |
🟡 Pale pink / whitish | Possible anemia or shock — monitor closely |
🟡 Bright brick red | Possible fever, infection, or heat stroke |
🔴 Blue/purple/gray | Not getting enough oxygen — VET NOW |
🔴 White as paper | Severe blood loss or shock — VET NOW |
Capillary refill test: Press your finger gently on the gum until it turns white, then release. It should turn pink again in 1–2 seconds. If it takes longer than 2 seconds, that’s a red flag.
Hydration Check (Skin Tent Test): Gently pinch the skin at the scruff (back of the neck), pull it up like a little tent, and let go.
- 🟢 Snaps back immediately — well hydrated
- 🟡 Takes 1–2 seconds — mild dehydration; offer water/Pedialyte, monitor
- 🔴 Stays tented or takes 3+ seconds — moderate to severe dehydration; needs fluids, call the rescue
Also watch for: Dry or sticky gums, sunken eyes, thick saliva.
🚨 Parvovirus (Parvo)
Parvo now has its own guide. See Puppy Parvo — Spot It Early, Act Fast for the full timeline, the signs that mean call now, what treatment involves, and how to disinfect afterward.
The Printable Packet
The Puppy Foster Packet gathers these as printable documents — the emergency-kit checklist, the daily checklist, the contact-and-rescue-info sheet, and a fold-up “when to call” wallet card. Print each one, fill it in, and keep it where you can grab it.
When in Doubt…
Text your rescue coordinator a photo or video. A 10-second video of a puppy breathing, eating, or behaving oddly is worth a thousand words. They’d much rather see 20 “this is probably fine” videos than miss one puppy who needed help.
Don’t wait until morning. Most puppy emergencies get worse, not better, with time. A puppy who seems “a little off” at 10pm can be critical by 3am. Call.
You are the expert on THESE puppies. You see them every day. You know their normal. If something feels wrong, trust that instinct — even if you can’t put it into words.
