Veterinary leaders warn of rising pepper spray exposure risk for pets

A new Veterinary Viewfinder episode is drawing attention to a problem many clinics may not have formally planned for: pets caught in the path of pepper spray, tear gas, pepper balls, and similar chemical agents used in public settings. In the episode, Dr. Ernie Ward and Beckie Mossor, RVT, speak with Steve Dale about what he describes as a surprising and underreported issue affecting dogs, cats, and other companion animals in U.S. cities.

The conversation appears to have been prompted by events in Chicago in late October 2025. In CBS Chicago coverage, Dale said there was growing concern about pets in neighborhoods where federal agents used tear gas, pepper balls, and smoke grenades. He warned that companion animals can be especially susceptible because their respiratory systems are more sensitive than humans’, and because their close-to-the-ground exposure may increase contact with residual irritants. He also flagged birds as a particular concern because of their sensitivity to fumes. (cbsnews.com)

That broader context matters because this is not just a public-safety story. It’s a veterinary preparedness story. ASPCA Poison Control says it is available around the clock for animal poison-related emergencies, and toxicology guidance published for veterinary teams notes that inhalation, ocular, and dermal decontamination may all come into play after chemical exposures. In that guidance, pepper spray is specifically called out as a hazard that can also affect veterinary staff if inhaled, meaning clinics need to think about secondary exposure, ventilation, PPE, and where decontamination should occur.

The clinical picture is consistent with what poison and toxicology sources describe for irritant exposures. Poison Control states that pepper spray can cause eye, skin, and mucous membrane irritation, with inhalation leading to coughing, breathing difficulty, throat and nasal irritation, and ocular exposure causing pain, redness, tearing, and light sensitivity. Dale’s practical description to CBS Chicago was similar: exposed pets may have runny eyes, appear distressed, and cough. Toxicology guidance for veterinary teams recommends removing the pet from the source, providing ventilation, evaluating for respiratory changes and hypoxia, and giving oxygen support when respiratory distress is present.

Expert reaction here is less about controversy than about awareness. Dale’s role in both the podcast and local media suggests he is trying to move this issue from anecdote to readiness planning. His advice to pet parents was straightforward: wipe the pet down, give it a few minutes, and contact a veterinarian if signs persist. For clinics, the more technical takeaway comes from toxicology literature: some animals may be too painful or stressed for safe decontamination without veterinary help, and sedation may occasionally be needed if the patient’s condition allows.

Why it matters: Veterinary teams are already trained for poisonings and environmental exposures, but crowd-control chemical exposure may fall into a gray zone between toxicology, emergency medicine, and disaster response. Practices in urban areas, mobile settings, shelters, and ER hospitals may want written protocols covering triage questions, staff PPE, outdoor or isolated decontamination space, and escalation triggers for dyspnea, persistent ocular pain, or worsening distress. There’s also a communication opportunity: pet parents may not realize that a pet exposed outdoors can carry irritants into cars, homes, and clinics, creating additional risk for handlers and staff.

This also intersects with access to toxicology support. ASPCA Poison Control explicitly positions itself as a resource for both pet parents and the veterinarians who support them, which may be useful in cases where the exact agent is unclear or mixed exposure is possible. In practice, that means clinics may need to collect details on whether the animal encountered pepper spray, tear gas, smoke devices, or another dispersal agent, because symptom severity, duration, and decontamination needs may differ. That last point is an inference based on standard toxicology workflow and the range of agents described in the Chicago reporting. (cbsnews.com)

What to watch: The next development is likely not a product recall or regulatory filing, but increased attention to protocols, CE discussions, and public guidance as more clinics recognize chemical-agent exposure as a real-world emergency scenario for companion animals, especially in dense urban markets.
