Elf Shoes

Elf Shoes grants a buck to be born with the rare dwarfism gene. These Bucks resemble the dog breed humans call "Corgi".

Elf Shoes causes the limbs of a buck to be stunted short

Elf shoes affect the buck it's applied to and have a chance to affect its offspring.

Elf Shoes only affects the buck's Feral form. (you can however choose to have it also affect the humanoid)

R= Recessive
D= Dominant

The dwarfism gene will not pass onto a buck that receives recessive copies or one recessive and one dominant. For dwarfism to pass onto an offspring, the pup will need two copies of the dominant gene.
Because of this unique trait, to successfully obtain a buck with dwarfism gene through breeding, you must breed two bucks that carrier either RD or DD.

R + R = No dwarfism
R + D = No dwarfism, but is a carrier
D + D = Dwarfism
