NEW: Man mauled to death in front of his 4-year-old son by his "bully dogs," in Mira Mesa, California.

Owning these dogs should be illegal.

26-year-old Pedro Ortega was killed by three of his own dogs.

The dogs turned red because they were so bloody and fled the scene after police tased them. One of the bulldogs wandered into a man's garage which was caught on surveillance camera.

Ortega was rushed to the hospital where he was pronounced de*d.

"Bully dogs" are a similar breed to pit bulls. It's unclear why they attacked.

All three dogs were euthanized.
