Can heat stroke cause permanent damage in dogs?

Heatstroke can cause widespread organ damage; and unfortunately, many do not survive. The prognosis depends on how high the body temperature gets and how long it remains elevated. Underlying conditions that already affect the dog can increase the risk of permanent damage or death.

Can heat stroke cause neurological damage?

Heatstroke can lead to neurological complications, such as cerebellar ataxia, cognitive impairment, dysphagia, and aphasia (Leon and Bouchama, 2015). Long-term studies have revealed cellular damage in various brain regions, including the cerebellum, hippocampus, midbrain, and thalamus (Lawton et al., 2019).
