Deformities in dog puppies may be caused by a variety of reasons, including but not limited to genetic mutations, genetic problems, environmental factors, improper breeding, etc. The specific cause requires professional diagnosis and analysis by a veterinarian.

For dog deformities, prevention is very important. Owners should choose regular kennels to buy dogs and avoid buying dogs from unknown sources or illegal breeding. At the same time, pregnant female dogs should be provided with adequate nutrition and appropriate exercise to avoid excessive stress and stimulation.
