My Pets:


Originally from Burlington, Ontario, Dr. John Murray obtained his DVM degree in 2008 from the Ontario Veterinary College and subsequently completed a rotating small animal internship at the Ontario Veterinary College. During this time, John developed an interest in emergency medicine. In 2009, John moved to Calgary to join the talented emergency team at the C.A.R.E. Centre. John considers emergency practice to be very rewarding and embraces the challenges and variety it provides, with particular interest in transfusion medicine, CPR, arrhythmias, trauma, and shock.

In his spare time, John enjoys basketball, soccer, snowboarding, camping, and hiking, and spending time with family including his Bernese Mountain Dog “Kramer”.

Cranial vena caval thrombosis associated with endocardial pacing leads in three dogs

Cranial vena caval thrombosis associated with endocardial pacing leads in three dogs

Objective: Three dogs were examined several years following implantation of transvenous, single-lead, endocardial, right-ventricular permanent pacing systems for signs consistent with cranial vena caval syndrome. Angiograms performed in all dogs revealed filling defects within the cranial vena cava and, in some instances, intracardiac filling defects. Medical therapy was instituted in two dogs, with one surviving several weeks. One dog underwent surgery to address intra-cardiac thrombosis but did not survive the immediate postoperative period. Postmortem examinations were performed in two dogs and confirmed cranial vena caval and intracardiac thrombosis. Cranial vena caval thrombosis associated with transvenous pacing leads appears to carry significant morbidity and mortality.

Emergency & Critical Care

VCA Canada CARE Centre Animal Hospital Emergency Service
Any time, every time. We are here for you and your pet 24 hours a day, 7 days a week, 365 days a year.

Our highly trained emergency veterinary health care team is dedicated to helping you and your companion any time of the day when your pet is sick or injured. No appointment is necessary.

Whenever possible, our veterinarians work in consultation with your primary care veterinarian.

We do everything possible to ensure that every patient receives timely access to veterinary care. Like human emergency rooms, we operate on a triage system – this means that more seriously ill or injured patients are seen before less seriously ill or injured patients. During high-volume times patients with minor ailments and injuries can experience longer wait times.

What happens “in the back”?
At times, potentially seriously injured or ill patients may be taken straight into our hospital’s triage room or treatment areas based on our triage system. These patients will be assess by a doctor immediately and receive life-saving treatment such as fluids and oxygen and/or pain medication when appropriate.

Financial Policy & Fee Structure
Each patient is charged an emergency consultation fee that covers the doctor’s initial examination and assessment. Additional fees are charged for all diagnostics and treatments required based on your pet’s medical condition. It is our policy to prepare a detailed estimate of your pet’s medical costs for your review on admission and keep clients updated on the ongoing medical costs of their hospitalized pets. We do not wish to extend anyone beyond their means. Please do not hesitate to communicate your intentions or concerns to your doctor.

Our fee schedule is structured to support a modern, fully equipped medical facility enabling our staff to deliver the highest possible quality veterinary services by highly trained staff. A 75% deposit is required for all hospitalized cases with the balance due in full at discharge.  For your convenience we accept cash, debit, AMEX, Visa & Master Card.

If you have financial concerns, please let us know as soon as possible. Whenever possible, we try to provide appropriate diagnostic and treatment options to ensure that your pet receives quality care. Please see our Payment Options page to learn about our financing options.
