Does bull-mastiff head split

Yes, bull mastiff puppies can experience a condition known as "head splitting," where their skulls appear to separate or develop a prominent ridge along the skull. This is due to the growth patterns of their bones and is most noticeable during their development. Typically, this condition resolves as they mature and their skulls fully form. However, it's important for owners to monitor their pets and consult a veterinarian if they have concerns.
