Obese and brachycephalics
What is the primary heat dissipation method for dogs?
What does heat stroke lead to?
DIC, SIRS, organ dysfunction, cardiovascular collapse
When does heat stroke occur?
When body's ability to dissipate heat is exceeded by the heat load
What results from hyperthermia?
Protein denaturation, apoptosis, activation of heat shock proteins
What is the heat critical temperature of dogs?
What are clinical signs of heat stroke?
Panting, staggering, collapse, altered mentation
Does a heat stroke patient always present with hyperthermia?
No, depends on timeline
How do you cool a hyperthermic animal?
Soak fur w/tepid water and fanning
At what temperature should you stop cooling methods and why?
