Which vascular outcome mitigates overheating during canine exercise?

💡 Explanation

Dermal vasodilation occurs because widening of blood vessels increases blood flow near the skin, promoting radiative heat loss, therefore lowers body temperature rather than vasoconstriction which conserves heat in core.
