Accessible Veterinary Emergency Care

The attention your pet needs for the unexpected.

Quality Care With a Kind Heart

We aim to be an integral part of Western Montana’s veterinary community, caring for patients that need extra attention and an after-hours presence.

We focus on communication between all parties involved- from owner education to hospital organization and outreach- in order to provide quality veterinary care.

Emergencies can be the most difficult things to handle in our lives. Our goal is to reduce stress so difficult decisions can be made with a clear mind.

As we diagnose and treat animals in pain, we provide education about the issues known and unknown. We provide options for the ideal therapy and help guide you to an understanding of the prognosis and what to expect for your loved one’s future.

Our team is organized efficiently so we can stay calm and focused, giving our best to everyone we serve.

OUR DOCTORS are well trained to manage critical patients and help rule out possible causes of illness. We seek out constant learning for new ways to reduce complications and help heal our furry friends.

OUR TECHNICIANS  are seasoned in caring for painful and stressed animals, paying close attention to subtle changes as they are monitored. Our assistants are passionate about learning more and being present in every way possible for you and your loved one.

OUR RECEPTIONISTS understand the stresses involved with emergencies and approach each individual based on their needs and ideal form of communication.

What To Expect


Our team will gather a brief history and assess stability.

You will fill out forms necessary to proceed with care.

If you would like, you may enter your information ahead of time on our online portal.              

You will be seen in order of arrival with critical patients taking priority.


A technician and veterinarian will be with you to evaluate your pet and provide insight into their condition and needs.

We will provide a treatment plan outlining the diagnostic and therapeutic options, along with estimated costs, to help plan your pet’s care.


Once we decide on the approach that best suits you and your pet’s needs, we will proceed.

Treatment approaches may include:

  • Symptomatic care
  • Baseline diagnostics & treatment
  • Hospitalization


After you settle your bill we will go over follow-up care and address any questions you may have.

A copy of your records will be emailed you and your pet’s primary provider.

In addition you will have online access to your records.


We take patients in the order that they arrive with priority given to critical patients.

Our team will inform you if any significant wait time is expected.

Symptomatic Care

Alleviating Discomfort

We will always discuss some of the most likely causes of your pet’s symptoms and advise you on the best follow-up care or diagnostics that your primary provider may perform.

Frequently, there are a number of possibilities that need to be ruled out. When there is no obvious reason to suspect a life-threatening disease we are glad to alleviate pain or other discomforts.

Diagnostic Approach

What We Offer

A physical exam and detailed history can help decipher what’s going on with your pet. Diagnostics are used to rule out primary causes of illness or injury. Additional diagnostics are necessary to rule out things we cannot see. Baseline diagnostics can rule out common primary causes or help direct treatment. For example, nausea can be from eating bad food, metabolic disease, renal disease, diabetes, gall bladder issues, and gastric ulcers, just to name a few.

Hospitalization and Monitoring

Keeping a close eye while offering ideal therapy.

From minor illnesses to critical issues we can keep an eye on your loved one.

We have the ability to watch for subtle changes and adjust therapy as needed while patients are in our care. In our hospital, we are able to provide most medications intravenously since sick patients may not properly adsorb oral therapy and require fluids to maintain adequate cardiovascular support.

Payment Policy

Payment is due at the time of service.

We take Care Credit. You may apply for this service online prior to your visit.

If this is an emergency, come in. We will take care of financial needs once your pet is stabilized.
