Case studies on the unexpected death of animals

Published in the December 2021 issue of the Vet Board's newsletter

The Vet Board frequently receives complaints relating to the unexpected death of an animal during or after delivery of veterinary services.

The death of an animal is always distressing, but much more so where that death may have been unforeseen. Good communication is paramount around such events, which can be challenging and stressful both for an animal’s owner and the treating veterinary practitioner.

Veterinary practitioners who are practising in Victoria should be aware that, in the event of an unexplained or unexpected death of an animal under their care, they are expected to offer an animal’s owner the option of arranging for a referral to another veterinary practitioner to undertake a necropsy (Board Guideline 18 – End of life veterinary services).

The two case studies in this article discuss complaints considered by the Board which involved the unexpected death of an animal. These case studies provide an opportunity for general reflection. Each case study is based on a complaint about an individual set of circumstances at a particular time.  As veterinary knowledge and professional and community standards and expectations change over time, readers should not assume that the Vet Board would make the same decision when presented with a similar complaint. 

Fido, a 10-year-old male desexed Blue Heeler, was presented to a veterinary practice by Ms Y with diarrhoea and reduced appetite.

Dr A examined Fido. Fido was depressed, had tachycardia and a tense abdomen. Haemorrhagic diarrhoea was detected on rectal examination.

Fido was admitted to the practice for blood tests, analgesia and intravenous fluids.

Blood tests revealed marked haemoconcentration, and a presumptive diagnosis of haemorrhagic gastroenteritis was made.

Fido appeared stable throughout the afternoon and was kept at the practice overnight to continue receiving intravenous fluids.

When staff arrived at the hospital the next morning, they found Fido had died overnight.

Ms Y was notified of Fido’s death over the phone. During the call, she became aware that Fido had not been monitored overnight. She elected to take Fido home for burial. A necropsy was not discussed.

Ms Y submitted a complaint to the Vet Board several months later. The complainant alleged inadequate care in that Dr A had failed to inform Ms Y that Fido would be unsupervised overnight. Ms Y believed that, if Fido had been monitored, he would have been able to receive further treatment and would not have died.

The Board delegated the complaint for preliminary investigation by a Preliminary Investigation Panel.

After preliminary investigation, the Panel recommended to the Board that an informal hearing take place into the professional conduct of Dr A, and the Board subsequently resolved to hold an informal hearing.

The allegations considered at the informal hearing were that Dr A had engaged in unprofessional conduct in that:
  • Dr A failed to inform Ms Y that Fido would be unsupervised overnight and failed to offer referral
  • Dr A failed to offer a necropsy.
Board Guideline 16.6 states, ‘Where an animal requires continuing care or hospitalisation outside normal business hours, a veterinary practitioner provides the owner with information on:
  • the nature and level of supervision of the animal provided outside normal business hours, and
  • the potential impact of restricted attendance on the animal’s expected course of recovery.’

Board Guideline 18.5 states, ‘In the event of an unexpected death of an animal under their care, a veterinary practitioner provides an owner with information on arranging a necropsy, including any anticipated limitations to necropsy results.’

Further, Board Guideline 18.6 states, ‘A veterinary practitioner refers an owner to another veterinary practitioner to carry out a necropsy, unless it is not possible or practical to do so and the owner provides informed consent.’

The informal hearing panel findings were that Dr A had engaged in unprofessional conduct, not of a serious nature, and that Dr A be counselled.

Counselling is one of the determinations that may be made following a finding of unprofessional conduct. It is a formal process during which the veterinary practitioner is informed of how their conduct failed to meet the minimum required standard and how that standard might be met in future.

A Panel may counsel in any way it sees fit. The counselling may be oral, written, given immediately or within 28 days of the determination. The determination is recorded on the veterinary practitioner’s file and may be referred to in any future hearing or action taken by the Board.

Spot, a 9-year-old female speyed Cavoodle, was presented to a veterinary practice with distress and breathing difficulties. Spot was panting but did not have laboured breathing. She was admitted to the practice for blood tests and investigation of a painful lump on her left hind leg.

Blood tests were unremarkable. Spot ate well during her hospitalisation. Pain relief was given and the panting subsequently improved. A biopsy of the leg mass was planned for the following day, as there was a concern that the mass was cancerous.

Spot was discharged that afternoon. Unfortunately, Spot’s condition rapidly deteriorated later that evening and she died while being transported to an emergency veterinary practice.

Several months later, Mr Z submitted a complaint about treating veterinary practitioner Dr B to the Board, alleging inadequate communication and that inadequate/negligent care of Spot resulted in Spot’s unanticipated death.

The Board delegated the complaint for preliminary investigation by a Preliminary Investigation Panel.

At the completion of the investigation, the Panel considered that:
  • the causes of the panting, distress and pain could not be definitively identified despite diagnostic testing having been performed
  • medical records detailing results of blood work, heart rate, mucous membrane colour, ability to walk, passage of faeces and voluntary consumption of food indicated that Spot was in a stable condition when discharged
  • a necropsy was performed at another practice and found:
    • small masses in the right lung lobes, the largest being 17 x 18 mm
    • some haemorrhage of the pericardium
    • the cause of the acute death was not grossly apparent
  • tissues were submitted for histopathology to a local pathology provider
    • the lung masses were found to be sarcomas, likely secondary tumours that had spread from a primary sarcoma that had been present on the leg (which records showed had been present for at least 8 months)
    • there were signs of inflammation in the pericardium, damage to the kidneys and liver
    • the pathologist suggested that the cause of the sudden death may have been disseminated intravascular coagulation.

After considering the information provided to it, the Preliminary Investigation Panel recommended to the Board that the matter should not proceed further.

The Panel found Dr B’s clinical management of Spot to have been reasonable and that there was no evidence of negligence or inadequate care. It also found that there was no evidence that the treatment provided to Spot contributed to her death, or that any treatment that could have prevented her death was withheld.

The panel noted that thoracic radiographs may have identified the tumours in the right lung and that this additional information would have been of benefit but would have provided a poor long-term prognosis for Spot. There was no way of predicting the development of the (suggested) terminal disseminated intravascular coagulation which occurred later that evening.

After considering the Panel’s recommendation, Board subsequently resolved that the matter should not proceed further.



Reflection and guidance

There are actions veterinary practitioners and animal owners can take in relation to the unexplained or unexpected death of an animal.

In Case Study 1, the veterinary practitioner did not provide sufficient information to the animal’s owner about overnight care arrangements for the animal, and they did not offer the owner the option of arranging for a referral to another veterinary practitioner to undertake a necropsy.

In Case Study 2, medical records indicated that the clinical management of the animal before discharge had been reasonable. Most importantly, an independent necropsy was undertaken by another veterinary practitioner. The findings from this necropsy assisted the Panel to find that there was no evidence that the treatment provided to Spot contributed to her death, or that any treatment that could have prevented her death was withheld.

Communication is key
Clear communication between the veterinary practitioner and the animal’s owner is essential at such times. The focus should be on collaborating to resolve any issues rather than on any perceived shortcomings in the animal’s care or treatment.

Under Board Guideline 4.12, ‘When an unexpected adverse event, including unexpected death of the animal, occurs during the provision of veterinary services, a veterinary practitioner has the responsibility to inform:
  1. the owner of:
    1. what happened
    2. any actions taken to rectify the event at the time it occurred
    3. what the short- and long-term consequences of the event are likely to be
    4. the availability of post-mortem examination
  2. the relevant authority of an adverse event involving the use, supply or administration of medicines, and
  3. the Board of the facts of the adverse event and resultant actions as part of any complaint investigation.’

Offering post-mortem examination
When an animal dies unexpectedly, it is appropriate to tell an animal’s owner that a post-mortem examination/necropsy can be performed to try to find out why the animal died. Veterinary practitioners should offer to arrange for referral to another veterinary practitioner to undertake the necropsy. Ideally the other veterinary practitioner would be independent from the current practice, as in Case Study 2. If an independent veterinary practitioner cannot be found to undertake a necropsy, the animal’s owner would need to give their informed consent to any necropsy being undertaken by the treating veterinary practitioner.

It is also important to communicate the costs of a necropsy to an animal’s owner. They would be expected to give their informed financial consent to a necropsy before it was undertaken.

As can be seen in Case Study 2, in addition to information about the clinical management of the animal, the results of a necropsy can help to provide transparency for an animal’s owner, the veterinary practitioner who treated the animal, and the Board (if a complaint is lodged about a matter).
