While dogs and lions are meat-eaters (carnivores), they don't necessarily *never* develop scurvy. Here's why:
* Scurvy is caused by a lack of vitamin C.
* Dogs and lions can get vitamin C from their diet. They can get it from the organs and other tissues of their prey.
However, it's true that dogs and lions are less likely to develop scurvy than humans because:
* Humans are the only animals that can't produce their own vitamin C. We need to get it from our diet.
* Dogs and lions have higher levels of vitamin C in their bodies naturally. This is because they have the genes to produce their own vitamin C, but the process is inefficient and they still need some dietary sources.
* Dog and lion diets are often rich in sources of vitamin C. For example, the liver and adrenal glands of prey animals are good sources of vitamin C.
So, while dogs and lions don't have a guaranteed immunity to scurvy, their diets and natural biology make them less vulnerable than humans.
