The owner should get worse.
The entire Pitt Bull breed should be EXTERMINATED. Anyone who thinks these animals are dogs, are full of you-know-what. These evil animals have no pain threshold. It’s clear by these photos that this evil animal continued his assault regardless, and I would not be surprised if the porcupine didn’t survive. People with pitt bulls who also have small children are placing their children’s lives in danger. These beasts can turn quite suddently and unexcectedly, no matter how “sweet they are”. You know why there are so many pitt bulls at animal shelters? Because their OWN owners become afraid of them. Pitt Bulls ARE NOT dogs and permits should be required to own them.
