Here's why:
* Endotherms are animals that regulate their own body temperature internally. They produce their own heat through metabolic processes. This allows them to maintain a stable body temperature regardless of the external environment.
* Ectotherms rely on external sources of heat, like the sun, to regulate their body temperature. Examples include reptiles and amphibians.
Toy poodles, like all dogs, are warm-blooded and maintain a consistent internal temperature. They shiver to generate heat when cold and pant to cool down when hot.
