Dog Anatomy in 3D: Skeleton, Organs and Super Nose
Dogs are built around one superpower: smell. Their noses and the smell areas of their brains are far bigger than ours, compared with body size. In the 3D Animal Anatomy simulator you can turn a dog around, look inside at its organs and see its skeleton, all in one place.

The dog skeleton
A dog's skeleton is built for running. It walks on its toes, the long bones of the legs act like springs, and its shoulder blades are not locked to the rest of the skeleton, which gives it a long stride.
Inside the dog
In the Inside view you can tap these labels on the 3D model:
- Brain
- A big part of it is built just for reading smells.
- Heart
- Pumps blood around the whole body, all day and night.
- Lungs
- Take in oxygen from the air with every breath.
- Intestines
- Long tubes that soak up food into the body.
Interesting facts about dogs
- A dog's nose has up to about 300 million scent receptors, against about 6 million in ours.
- Dogs walk on their toes, not on flat feet like us.
- Adult dogs have 42 teeth, including long canines for gripping.
- They cool down mainly by panting, because they have few sweat glands outside the paw pads.
- The wet surface of the nose helps catch scent particles from the air.
