Toy is a mutation that makes Kises smaller than normal: the smaller common Kise that you could see around will have be around 1,5 meters, but these kises can be smaller, up to 50 cm at the withers!
Toys weren't appreciated in the past since they are usually results of inbreed and they couldn't be useful for heavy jobs (Infact, inbreeding increases the chances to have Toy Kises, however there are small chances to get one as random mutation in normal breedings).
But lately people started to like them as pet or messenger, thanks to their small size, they are greatly demanded.
In description you have to write "Dwarf" in Size section and "Toy" in Mutation.
However, due to their mutation, Toy Kises can only have a maximum of 2 puppies in a nest.
Thanks to their size, they get different statistics: ATK -1, DEF -1 and DXT +2.
