Bigstock New claims data suggest veterinary teams across the United States may see a predictable seasonal rise in heat-related illness, environmental injuries, and other preventable emergencies during the summer months. An analysis of Trupanion-insured cats and dogs from 2021 to 2025 found that, compared with the rest of the year, U.S. summer claims increased by 266 percent for heatstroke, 288 percent for foxtail injuries, 145 percent for snake bites, and 82 percent for insect bites during June through August. Traffic-related injuries—including pets struck by vehicles or injured while traveling in vehicles—also increased by 13 percent. Regional differences were evident across the country. California recorded the highest number of foxtail-related claims, while North Carolina reported the greatest number of snake bite claims. Florida saw high numbers of insect bite claims but relatively few foxtail cases. The analysis also noted that some northern states, including Connecticut and Idaho, recorded more heatstroke claims than Arizona, highlighting that heat-related illness is not limited to traditionally hot climates. Average treatment costs varied by condition, with claims averaging $1,673 for canine heatstroke and $1,319 for snake bites. For cats, average heatstroke and snake bite claims reached $1,890 and $1,960, respectively. The findings reinforce the importance of seasonal client education on heat safety, environmental hazards such as foxtails, parasite and insect exposure, and safe transportation practices. They also emphasize the need for region-specific preventive messaging based on local risks. The analysis was based on claims from Trupanion-insured pets in the United States and Canada between January 2021 and December 2025. Because the data reflect only insured animals, the overall incidence of these seasonal emergencies is likely higher. For more information, visit the Trupanion website.
