Meet Ranger, a German Shepherd who is 4 years old, but looks like a little puppy. The fact is that the dog has an inherited genetic disorder. The animal grow only a third of the standard size of his breed. This disorder is called animal dwarfism.

In case of Ranger pituitary dwarfism was caused because of inbreeding, closely related crossing.

According to the veterinarian Lynn the development of the dog is slowed from about two month of age because of the lack of growth hormone.

Dogs with this disorder are quite small and do not have the thick fur that adult dogs should have. Their fur usually remains fluffy, soft and short.

Ranger’s owner takes good care of the dog. Shelby Mayo carefully follows the health of the dog, feeds him properly and often takes for a walk.

Unfortunately dwarfism shortens animals’ life. Dogs with this disease die before reaching 3 years of age.

Thanks to good care Ranger is in good health. Shelby created an Instagram account for her pet, and often shares photos from this beloved dog. The dog has more than 160 thousand subscribers.

Dog owners quite often ask Shelby to breed dwarf Shepherd dogs, but the woman realizing that dwarfism shortens animals’ life refuse. The woman’s behavior is so reasonable and justifying.
