Achondroplastic Dwarf Horses
Achondroplastic dwarfism (also known as achondrodystrophic dwarfism)
refers to a horse that possesses a normal-sized torso neck and head with
abbreviated leg and ear length.
The Achondroplastic dwarf may have the following physical
characteristics (Figure 1). This is “Spot” a dwarf (deliberately bred
from a dwarf mother). She has very crooked legs and has received surgery
to repair her constricted tendons. While still crippled, she takes
regular Adaquin injections and she can now gallop freely and lives a
relatively pain-free life. Note that her characteristics include:
- Short limbs
- Normal torso and neck
- Normal intelligence
- Normal internal organs
- Small ears

Another example of an Achondroplastic dwarf is Twinkie (Figure 2), who
was lucky to have good legs and overall health. Aside from trauma from
having traumatized from having been bred (she lost her baby), Twinkie is now spayed and is a
happy and healthy 17-year old.
