Disorder - AchondroplasiaOrgan Systems Involved
A condition in which bone growth and development is slowed so that bones of the limbs, head and body may be shortened, resulting in a dwarf animal.
This disorder involves reduced bone growth and development and causes dwarfism in animals. Dwarf dogs may also have disproportionately short limbs, deformed limbs, or deformed bones of the head and body. Limb deformities often involve bowed forelimbs, while deformities in the bones of the skull may be indicated by constricted nostrils. An affected dog is usually less than half the size of normal mature dogs of the same breed. Achondroplasia may be suspected at fourteen days old if a dog does not gain weight as rapidly as its littermates. At four weeks of age affected dogs may be detected by an X-ray of the front foot. Around eight to twelve weeks of age affected dogs may be beginning to show skeletal deformities such as shortened and bowed forelimbs or abnormally shaped elbow and hip joints. Dogs that display dwarfism but are not deformed, and possess body parts in proportion may live a normal life with few health problems. Dogs displaying greater degree of deformity and a larger number of associated conditions will have a shorter life-span and a decreased quality of life. The most severely affected animals die a few days after birth.
