A veterinarian who sedated and euthanized two dogs after they entered his property can face several civil claims, including veterinary negligence, a Washington appeals court ruled. The April 2026 decision turned in part on whether the veterinarian was acting professionally or as a property owner protecting his livestock.
In Bean v. Portenier, the Court of Appeals reversed a lower court’s summary judgment ruling on most of the claims brought by Tyler and Leticia Bean, the dogs’ owners. The decision does not establish that the veterinarian was negligent or liable. Instead, the court found unresolved factual questions that must be addressed in further proceedings.
The case highlights a legal question for veterinarians: When does using veterinary training and prescription medications outside an established veterinary-client-patient relationship (VCPR) expose a veterinarian to professional liability?
Why a Veterinarian Faced Civil Claims After Euthanizing Two Dogs
The dispute began in February 2023, when the Beans’ two Siberian huskies escaped their yard in rural Pierce County, Washington, and entered property owned by Dr. Mardez Portenier, DVM, who kept sheep there.
Portenier said he saw the dogs biting sheep, including animals that were dead or seriously injured. He also reported that one dog growled and snapped at him. Rather than killing the dogs immediately, he restrained them with leashes and administered xylazine to sedate them.
About 45 minutes later, Portenier returned to the dogs and observed that their vital signs were poor and they were twitching. He then administered propofol and lidocaine, and the dogs died.
The Beans sued, alleging negligence, conversion, trespass to chattels, breach of gratuitous bailment, malicious injury to an animal and veterinary negligence. Portenier argued that Washington law allowed him to kill dogs caught attacking livestock and that his actions were justified under the common-law defense of property.
The trial court granted summary judgment in Portenier’s favor, dismissing the claims. The Beans appealed.
When Can Livestock Owners Legally Kill Dogs Attacking Sheep?
The Court of Appeals found that Washington’s livestock-defense statute did not protect Portenier’s actions because he killed the dogs well after observing the alleged attack. The statute allows a person to kill a dog seen chasing, biting, injuring or killing livestock, but the court concluded it did not apply under these circumstances.
The court also rejected the common-law defense of property as a basis for summary judgment. By the time Portenier euthanized the dogs, they had been sedated and confined. The court concluded that killing them was no longer reasonably necessary to protect his sheep.
As a result, the court reversed summary judgment on the Beans’ negligence, conversion, trespass to chattels and gratuitous bailment claims. It found unresolved questions about whether Portenier had unjustifiably interfered with the dogs as property and whether his actions met the applicable negligence standards.
The court reached a different conclusion on the claim for malicious injury to an animal. Although the Beans pointed to allegations of excessive sedation and questions about the euthanasia method, the court found insufficient evidence that Portenier acted with malice. It affirmed dismissal of that claim.
Can a Veterinarian Face Negligence Claims Without a VCPR?
The veterinary-negligence claim centered on whether Portenier was acting in his professional capacity when he sedated and euthanized the dogs. Both parties agreed that he had no VCPR with them and had never served as their veterinarian.
Portenier argued that without a professional relationship, no professional duty arose. The Beans argued that he made clinical decisions, used his veterinary training and administered prescription medications available to him through his veterinary credentials.
The appeals court concluded that the absence of a VCPR was not, by itself, enough to defeat the veterinary-negligence claim. The key question was whether Portenier acted in a personal capacity as a sheep and property owner or in a professional capacity as a veterinarian.
The court found evidence supporting both interpretations. Portenier was protecting his property, but he also used veterinary knowledge and medications to make decisions about the dogs’ sedation and deaths. That created a genuine issue of material fact that could not be resolved through summary judgment.
The Beans submitted an expert report from Dr. Heidi Shafford, DVM, who questioned the dosing and treatment decisions. Shafford estimated that the dogs may have received a xylazine dose five to 10 times greater than appropriate for a 100-pound dog. She also opined that the overdose was not necessarily fatal, that Portenier should have sought outside assistance and that the medications used for euthanasia would not produce a quick, painless death.
These were expert opinions submitted in the case, not findings made by the appeals court. The ruling addressed whether factual questions remained that could allow the veterinary-negligence claim to proceed. It did not determine whether Portenier’s treatment was negligent.
What the Ruling Means for Veterinary Liability and Professional Conduct
The decision does not establish that every veterinarian who intervenes in an animal emergency assumes professional liability, nor does it eliminate the importance of a VCPR. It does show that the absence of a formal client-patient relationship may not end a veterinary-negligence claim when the veterinarian’s conduct could have been professional in nature.
For veterinarians, the case highlights the potential legal risks of making treatment decisions outside a normal practice setting. When intervening as a property owner or livestock producer, veterinarians may still face questions about their professional conduct if they use veterinary training, make clinical decisions or administer prescription medications.
The Pierce County docket lists a mandatory court review hearing for Nov. 20, 2026. The available docket information does not establish a trial date or indicate how the remaining claims will be resolved.
