Here are some categories of animals that are generally considered "short" compared to their relatives:
By Height:
* Dwarf breeds: Many animals have dwarf breeds, like dogs, cats, goats, horses, and rabbits. These breeds are significantly shorter than their standard counterparts.
* Small mammals: Shrews, mice, voles, hamsters, and some bats are known for their small stature.
* Reptiles: Some snakes like the thread snake are extremely thin and short.
* Insects: Most insects are naturally small, with many reaching only a few millimeters in length.
By Length:

* Amphibians: Many frogs and salamanders are quite small, with some species being less than an inch long.
