Emergency vet options in Las Vegas: what to do after hours

Think it's an emergency? Call a vet now. This page helps you find one. It isn't medical advice.

Las Vegas never closes, but most vet clinics do. When something goes wrong at 2 a.m. on a holiday weekend, you don't want to be searching for a phone number. Read this now, save the numbers, and you'll know where to turn.

From our directory: 24-hour emergency clinics

As of Oct 30, 2026, our directory lists 4 24-hour emergency clinics across the valley. They're in alphabetical order, and we don't rank or recommend any of them.

• Tropicana Animal Hospital · Paradise / East Las Vegas · 702-736-4944
• VEG ER for Pets - Henderson · Henderson / Green Valley · 702-529-4850
• VEG ER for Pets - Las Vegas · Summerlin / West Las Vegas · 702-790-8242
• Veterinary Emergency + Critical Care (VE+CC) · Spring Valley / Southwest Las Vegas · 702-262-7070

The valley is big, and getting across it at night can take longer than you'd expect, especially with Strip or I-15 traffic. Work out now which clinic is closest to your home and which is closest to work. Call before you set off. The AVMA suggests calling ahead so the team can get ready, and it's a chance to check they can see you right away. Every clinic's listing has its address and published hours.

Your own vet comes first

The FDA's advice to pet owners is to start with your regular veterinarian whenever you can, because they know your pet's history. During business hours, call them first. Listen to the whole message if you reach their voicemail, since it may include after-hours instructions. If you can't get through, call an emergency clinic and let their staff tell you whether to come in.

If your pet swallowed something

Two national poison hotlines for animals have veterinary specialists on call around the clock, every day of the year. Expect a consultation fee.

• ASPCA Animal Poison Control Center: (888) 426-4435
• Pet Poison Helpline: (855) 764-7661

Before you dial, grab the wrapper, bottle or box so you can read out exactly what it was. Have a rough idea of how much your pet ate, when it happened and how much your pet weighs. Bring the packaging to the clinic too. The national Poison Help line (1-800-222-1222) is for people, so call one of the animal lines above for your pet.

When not to wait

The AVMA says to call right away if your pet has eaten or touched something that could be toxic, has a seizure, collapses or struggles to breathe. Serious injuries, heavy bleeding and suspected heatstroke also call for an immediate phone call. Heatstroke is a real risk here from spring through fall (see our heat safety guide). If you're not sure whether it's serious, call anyway. Emergency clinics expect those calls.

Get ready tonight

• Save three numbers: your vet, your nearest 24-hour clinic and one animal poison line.
• Keep a folder: your pet's records, vaccine dates, current medications and recent weight, on paper or your phone.
• Plan the ride. Have a carrier for small pets, and a blanket or a second person to help lift a big dog. Know where you'll park.
• Brief your sitter or walker on your vet, the nearest clinic and what they're allowed to approve while you're away.
• Ask about fees and payment when you call, so there are no surprises at the front desk.
• Keep a basic first aid kit. The AVMA publishes a checklist. It's for getting your pet to the vet safely, not a replacement for the visit.

Someone else's animal in danger

For an animal in danger that isn't yours, such as a dog shut in a hot car, Clark County asks you to call 911 or Animal Protection Services at (702) 455-7710.
