Emergency and 24-hour vets in Denver
22 emergency or 24-hour veterinary hospitals are mapped within about nine miles of central Denver. Call before you drive: they will tell you whether to come, what to do on the way, and whether a closer hospital is open. Keep this page bookmarked; nobody searches calmly at 2 a.m.
Denver has real winters: below about 20°F short-coated and small dogs need a coat and shorter walks, and road salt should be rinsed off paws. Summer afternoons still get hot enough to watch the pavement. 3 of these are marked open around the clock.
The 22 emergency and 24-hour vets, closest first
Before you go
- Go now, not in the morning, for: trouble breathing, collapse, a bloated hard belly, repeated vomiting, a seizure lasting over a few minutes, a bite wound, eating something toxic, being hit by a car, straining to pee (especially a male cat).
- If they ate something toxic, bring the packaging. ASPCA Animal Poison Control: (888) 426-4435 (a fee applies).
- Expect an exam fee of $100–$250 on arrival, with a deposit before treatment; ask for an estimate in writing.
What works
- Keep a towel, a slip lead and a carrier in the car; an injured animal bites.
- Do not give human painkillers: acetaminophen and ibuprofen are poisonous to cats and dogs.
- For heatstroke, cool with lukewarm water on the way, not ice.
- If your regular clinic is open, call them first; they may see you faster and know the history.
- Ask whether the hospital has a vet on site around the clock or on call; the sign says 24-hour either way.
