Nature is full of surprises, and sometimes it loves to mix things up. A German shepherd named Ranger is two years old, but he still looks like a puppy. The dog’s size is the same as when he was born. When he was still a puppy he caught an infection that affected his body’s ability to produce growth hormones. Ranger has fully recovered but retained his puppy-like appearance.
He has turned 2, but still hasn’t grown in size
The dog had an infection very early in life that stopped his growth
He somehow contracted a parasite named Giardia that caused an infection in the frontal lobe. His owners got rid of the parasites, but pituitary dwarfism persisted as a side effect.
