What is the recommendation if a dog's temperature reaches 105°F?

When a dog's temperature reaches 105°F, it indicates a state of hyperthermia or potential heatstroke, which can lead to serious health complications if not addressed promptly. Seeking medical attention in such a scenario is crucial because a high body temperature can result in organ dysfunction, brain damage, or even death. Veterinary professionals can provide the necessary interventions, such as intravenous fluids, medications, and monitoring, to mitigate the risks associated with elevated body temperatures.

In contrast, the other options involve actions that could worsen the dog's condition. Stopping cooling measures may lead to a further increase in body temperature, while continuing outdoor exercise is inappropriate as it could contribute to overheating. Giving medication at home without professional guidance is risky, as the incorrect dosage or type of medication could have detrimental effects. Therefore, immediate veterinary care is the recommended course of action when a dog's temperature becomes critically high.
