It’s 11:47 p.m. and your dog just ate a handful of raisins, or your cat is straining in the litter box and crying. Your regular vet is closed. Do you jump in the car and head to the 24-hour emergency clinic, or call the on‑call vet first? That decision can save time, money, and in some cases, a life. After-hours care isn’t one-size-fits-all: some problems need immediate ER intervention, while others can be triaged safely over the phone and monitored at home. You’ll get clear criteria for true emergencies, practical steps for quick triage, and what professionals wish pet owners knew at midnight. By the end, you’ll feel comfortable making the call—literally and figuratively—so your pet gets the right care, right now.
Quick Answer
If your pet has life-threatening signs—trouble breathing, severe bleeding, seizures over 5 minutes or repeated seizures, suspected bloat, inability to urinate, hit-by-car—go straight to a 24-hour emergency clinic. If the situation is non-urgent or unclear, call the on‑call vet first for guided triage; they’ll tell you whether to head to ER immediately or how to safely monitor.
Why This Matters
Deciding where to go in the middle of the night impacts your pet’s outcome and your wallet. Some conditions are measured in minutes, not hours. A male cat with a urinary blockage can develop dangerous electrolyte shifts and kidney failure within 24–48 hours; waiting until morning can be the difference between a simple unblocking and intensive care. Dogs with suspected bloat (gastric dilatation-volvulus) often show unproductive retching and a tight abdomen—delays increase complication risk and mortality.
On the other hand, a dog that vomited once but is bright and comfortable may not need ER-level care at 1 a.m., and an on‑call vet can talk you through what to watch and when to escalate. Choosing wisely prevents overcrowded ERs, reduces stress for your pet, and avoids unnecessary costs. You’ll learn how to identify red flags, what info to share on the phone, and how to transport safely when seconds count.
Step-by-Step Guide
Step 1: Do a 60-second home triage
Check the basics while staying calm. Note breathing, behavior, and gums. You might find should i go to a 24 hour emergency clinic or call the on-call vet first kit helpful.
- Breathing: Count breaths at rest for 30 seconds and double it. Dogs: normal ~10–30/min; cats: ~16–30/min. Over 40 at rest or labored breaths = ER now.
- Gums: Pink is normal. White, blue, or brick-red gums suggest shock or poor oxygenation—go ER.
- Heart rate: Dogs ~60–120/min (smaller dogs run higher); cats ~140–220/min. If a calm pet’s heart is racing and they look distressed, that’s concerning.
- Temperature: Dogs 99.5–102.5°F; cats 100–102.5°F. Over 104°F or under 98°F is urgent.
- Behavior: Collapse, severe pain, repeated vomiting, unproductive retching, or inability to urinate are red flags.
Step 2: Call the on‑call vet for guided triage
If no immediate red flags, get professional eyes on the situation. Have details ready:
- What happened, when, and how much (e.g., “ate 4 raisins at 11:45 p.m.”).
- Current vitals and signs (breathing rate, gum color, temperature).
- Photos or short video of breathing pattern, gait, or swelling if requested.
- Medications, chronic conditions, and any toxins involved (xylitol, chocolate, lilies, antifreeze).
Follow instructions closely. The on‑call vet can often determine if home monitoring is safe or if you should head to ER right away. Don’t give medications unless they specifically advise—some human meds are dangerous to pets.
Step 3: Decide and move—safely
If advised to go to ER, leave now. Call the ER to say you’re en route so they’re ready. You might find should i go to a 24 hour emergency clinic or call the on-call vet first tool helpful.
- Transport: Use a secure carrier for cats; for painful dogs, support large dogs with a blanket sling. Consider a soft muzzle for dogs if they’re painful (never if vomiting or struggling to breathe).
- Do not feed your pet; no food, no water if surgery or sedation may be needed.
- Bring a list of meds, allergies, and your pet’s medical records if you have them.
Step 4: Know what to expect at the 24-hour clinic
Most ERs triage on arrival. Critical cases go first; stable pets may wait.
- Costs vary: exam $75–$150; diagnostics (x-rays, labs) $200–$800; hospitalization or surgery can exceed $1,000–$3,000. Ask for estimates and options.
- They may place an IV, give pain relief, or stabilize breathing right away.
- Be ready to authorize treatment and discuss finances; deposits are common for major care.
Step 5: If monitoring at home, do it like a pro
Write down times and observations. Set alarms to recheck every 30–60 minutes initially.
- Measure resting breathing rates and note changes.
- Watch for worsening: repeated vomiting, bloating, lethargy, swelling of the face/muzzle, or new pain.
- If anything deteriorates or you feel unsure, escalate to ER—trust your gut.
Step 6: Prepare ahead to avoid midnight panic
Pre-planning saves precious minutes. You might find should i go to a 24 hour emergency clinic or call the on-call vet first equipment helpful.
- Save contacts for your regular clinic, on‑call line, and nearest 24-hour ER.
- Know your route and backup ERs; drive time matters.
- Keep an emergency kit: digital thermometer, lubricant, gauze, vet-approved muzzle, carrier, towels.
- Understand your pet insurance and set aside an emergency fund. Average ER visits often total $300–$1,500 depending on work-up and care.
Expert Insights
From the ER side, the toughest cases are the ones that waited just a little too long. A male cat “trying” to urinate but only producing drops can look okay, then crash fast—urinary blockage is a go-now problem. Dogs with bloat often attempt to vomit without producing anything, pace, drool, and have a tight abdomen; don’t watch and wait on that. Breathing trumps everything: if your pet can’t breathe comfortably, every minute counts.
Common misconceptions: “He seems fine after being hit by a car” still warrants immediate exam—internal bleeding and lung bruising aren’t visible and can worsen overnight. “She only vomited twice” can be okay if the pet is bright, hydrated, and resting, but repeated vomiting, blood, or lethargy changes the calculus.
Pro tips: Know your pet’s normal resting respiratory rate while asleep; write it down. For toxins, time matters—xylitol in dogs can cause hypoglycemia quickly, and even one piece of gum can be enough. Never use hydrogen peroxide to induce vomiting in cats; in dogs, only under veterinary direction and with the correct 3% solution. Calling ahead saves 10–15 minutes of triage and gets oxygen or pain control set up before you arrive.
Quick Checklist

Frequently Asked Questions
What if I can’t reach the on‑call vet?
If your pet has red flags (trouble breathing, severe bleeding, seizures, collapse, suspected bloat, inability to urinate), go straight to the 24-hour emergency clinic. If it seems minor but you’re worried, try the nearest ER or a pet poison helpline for toxin guidance. Uncertainty plus concerning signs should tip you toward the ER.
How do I know breathing is an emergency versus normal panting?
Normal panting has a regular rhythm and the pet can rest, lie down, and focus. Emergency breathing looks labored: wide nostrils, belly effort, open-mouth breathing in cats, or breathing over 40 breaths per minute at true rest. Blue or very pale gums, fainting, or noisy breathing are immediate ER signs.
Should I give hydrogen peroxide if my dog ate something toxic?
Only under veterinary direction and only the 3% solution. Some substances (caustics, oils) should not be vomited, and incorrect dosing can cause aspiration or ulcers. Never use hydrogen peroxide in cats. Call the on‑call vet; they’ll advise whether to induce vomiting, come right in, or monitor based on timing and what was ingested.
What counts as an emergency seizure?
A single seizure that lasts longer than 5 minutes, multiple seizures within 24 hours (cluster seizures), or a seizure followed by prolonged disorientation or breathing trouble warrants immediate ER care. If your pet has known epilepsy and short, self-limiting seizures, call the on‑call vet; they may adjust meds or still recommend ER depending on frequency.
Is vomiting at night always an emergency?
Not always. One or two episodes in a bright, comfortable pet that can keep water down may be monitored with guidance from an on‑call vet. Go ER if there’s repeated vomiting, blood, a bloated or painful abdomen, lethargy, known toxin exposure, puppies or small breeds at risk of hypoglycemia, or underlying conditions like diabetes.
What should I do if my male cat can’t urinate?
Go to a 24-hour emergency clinic immediately. Urinary blockage can become life-threatening within 24–48 hours, and earlier in some cats. Signs include frequent trips to the litter box with little output, crying, vomiting, and a firm, painful abdomen. This is not a wait-and-see situation.
How much will an ER visit cost compared to calling the on‑call vet?
ER exams typically range $75–$150, diagnostics $200–$800, and hospitalization or surgery can exceed $1,000–$3,000. An on‑call consultation may guide safe home monitoring for minor issues, preventing unnecessary ER expenses. The priority is safety—if red flags are present, go to ER despite cost concerns and discuss estimates once stabilized.
Conclusion
Middle-of-the-night decisions feel heavy, but a simple approach helps: act immediately for clear red flags and use your on‑call vet’s expertise when the situation isn’t black and white. Do a quick triage, make the call, and move fast if advised to head to the ER. Set yourself up now with contacts, a kit, and baseline vitals so you’re confident under pressure. Your calm, informed choices are a big part of good outcomes—trust your instincts and prioritize breathing, pain, and toxins first.
