Emergency & Critical Care Services

Mile High Animal Hospital of Aurora accepts emergencies any time our facility is open. Emergencies can be events such as rat bait poisoning, chocolate ingestion, vomiting uncontrollably, a laceration, and one of the scariest: a beloved pet being hit by a car.

If your pet has a life-threatening emergency, please call us immediately at 303.693.6484 so that a staff member can advise you on your particular emergency. Many urgent situations can be treated here, while others might be referred to a 24-hour emergency veterinary center.

If you have an emergency with your cat or dog after we’re closed for the day, please scroll down to see the list below for 24/7 emergency vet clinics in metro Denver, Colorado.

Mondays-Fridays: 8 am – 7 pm
Saturdays & Sundays: 9 am – 5 pm


Our Location:

Mile High Animal Hospital of Aurora Critical-care Protocol

We also are available for urgent care when the condition is not life-threatening but still needs to be escalated. If you feel your pet needs to be seen by a veterinarian before you are able to get a regular appointment (critical care but not life-threatening), our veterinarians will work to “squeeze” you in between scheduled appointments. When you arrive, our team will be able to give you an idea of how long you may have to wait in order to be seen.
