Hyperthermia may occur in which type of animals, particularly during hot weather?

1. Brachycephalic breeds

2. Working dogs only

3. All animals regardless of breed

4. Only older animals

The correct answer is: Brachycephalic breeds

Hyperthermia, which refers to an abnormally high body temperature, can occur in brachycephalic breeds, particularly during hot weather. These breeds, characterized by their short snouts and flat faces, such as Bulldogs, Pugs, and Persian cats, have a compromised ability to regulate their body temperature effectively. Their anatomical features can lead to decreased airflow and increased respiratory difficulties, making it harder for them to cool themselves through panting. During hot weather, these dogs are particularly vulnerable because their inefficient cooling mechanisms can quickly lead to overheating. While other animals might also be at risk under extreme conditions, brachycephalic breeds are especially susceptible due to their unique physiological traits. The other options do not accurately reflect the specific risk associated with hyperthermia. Working dogs, while they can certainly be affected by heat, are not the only group at risk, nor are all animals equally vulnerable. Additionally, hyperthermia is not limited to older animals; it can affect individuals across age groups if they belong to breeds that struggle with heat regulation.
