What's going on with your puppy?
General tips, not vet advice. Emergency signs: trouble breathing (fast or open-mouth breathing while resting, pale or bluish gums, or the belly working hard to breathe); collapse, limp, won't respond, or a seizure; a puppy that's limp and cold; a swollen or bloated belly, or trying to throw up with nothing coming out; overheating (heavy panting, drooling, vomiting, weakness, confusion or collapse in the heat); or heavy bleeding. If you see any of these: This can't wait. Call your vet or an emergency vet now. If a person is hurt, call 911. Then call your rescue's foster contact. For everything else, answer two questions below.

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 |
Ask your rescue whether they want you taking temperatures, and how. If they do, use a digital thermometer kept just for the puppies.
Get to know each puppy's breathing while it sleeps, so you notice a change. Fast or open-mouth breathing while resting, bluish gums, or the belly working hard to breathe: This can't wait. Call your vet or an emergency vet now. If a person is hurt, call 911.
Lift the lip and look at a pink part of the gums, so you know each puppy's normal color. Pale or white, blue or purple gums: This can't wait. Call your vet or an emergency vet now. If a person is hurt, call 911. Then call your rescue's foster contact.
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
If it's slow to settle back, or the gums feel dry or sticky, call your rescue's foster contact or your vet now. If the skin stays up: This can't wait. Call your vet or an emergency vet now. If a person is hurt, call 911.
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.
