Pet emergency medicine by BluePearl.

Pet emergencies can be scary – we’re here to help you handle them.

We understand that seeing your pet sick, hurt or in distress can be stressful – especially if you don’t know what’s wrong. Fortunately, our experienced ER clinicians are prepared to take action and help.

We know an unexpected trip to the emergency pet hospital can be stressful, and we want you to be prepared so you have one less thing to worry about. Our entire BluePearl team will be with you every step of the way.

Before your visit

  • If possible, call us before arriving so we can discuss your pet’s condition, help you with directions and prepare our team.
  • Collect your pet’s medical records, current medication or any historical information.
  • If your pet has eaten something potentially toxic, bring the substance with you if it’s safe to do so.

During your visit

  • When you arrive, let us know if you need help bringing your pet in from the car, and we’ll be ready to assist you.
  • Our team will perform an initial triage exam on your pet to assess their condition.
  • To stabilize your pet, we may need to administer IV fluids, pain medications, oxygen therapy and sometimes blood or plasma transfusions.
  • Before you leave, you’ll receive discharge instructions and a list of any recommended medications.

After your visit

  • We’ll let your family veterinarian know about your pet’s condition and the treatment they receive at BluePearl. This communication is key in the ongoing management of your pet’s care.
  • You know your pet better than anyone, and you play a crucial role in any follow-up treatment necessary. If you have any concerns about providing care at home (such as giving medication or monitoring your pet’s symptoms), let us know – we’re here for you.
