The statement that dogs are not mammals is false and likely a misunderstanding. Here's why:
* Mammals share key characteristics: Dogs possess all the traits that define mammals:
* They give birth to live young (not eggs).
* They nurse their offspring with milk from mammary glands.
* They have hair or fur covering their bodies.
* They are warm-blooded, maintaining a consistent internal temperature.
* They breathe air through lungs.
* They have a more complex brain structure compared to other animal classes.
* Scientific classification: Dogs belong to the order Carnivora, family Canidae, and genus Canis. This places them firmly within the class Mammalia.
Perhaps the confusion arises from the fact that dogs are domesticated animals, and sometimes their behavior or appearance can seem different from wild mammals. However, their biological classification remains clear: they are mammals.
