A barking mad Russian man is accused of keeping a pitbull as his personal sex slave.

The abused dog has since been rescued by animal rights activists.

According to Russian news site kp.ru, Ramzes had been taken off the street in Salavat in the south central republic of Bashkortostan.

Cops became involved when the man was brazenly spotted raping the dog in a local park. They called animal rights activists.

"The rectum had severe deformations. It certainly seems as if the dog was raped more than once,” vet Aynur Makaev told the website.

The vet added that they had considered putting Ramzes down because of severe internal injuries but changed their mind.

Animal rights activist Elena Zhdanova, who the dog now lives with, added: "He is really getting better. He regained his appetite and finally managed to relieve himself as well."

As for the defiled dog’s twisted owner, he was fined just $45 for offending public decency for his canine carnal capers.

Thousands have signed a petition demanding the sicko be prosecuted.
