Breeding
Dwarfism in German Shepherds is due mainly to certain breeding practices. A puppy can acquire the condition if both parents carry the gene. Most often, this occurs when inbreeding is involved. Breeders can avoid this, but a small percentage of them don’t care about the animals’ well-being.
This condition is caused by commercial breeders, breeders that don’t care about the animals’ well-being, but are purely motivated by the money they earn through selling puppies. They aren’t bothered by the chance of dogs encountering genetic issues through their breeding practices.
The condition thankfully only has an effect on his physical health…
