Bulldogs are in high demand, but there is a growing concern over the breed.

There are nearly no more natural births for purebred English Bulldogs.They need to be delivered by cesarean section. This is largely do to breeding for specific traits for ‘best in show’, including large wrinkly heads and smaller hind quarters.

Now a groundbreaking English Bulldog DNA study conducted in a lab by UC Davis Professor Niels Pederson shows just how dim the future is for this breed.

Pederson discovered that bulldogs are very closely related, as almost every purebred English Bulldog in the world can be traced to the same paternal line.
