ginga densetsu weed 

popular japanese anime where the main character (Weed) searches for his father as his mother's last wish in the paradise of Ohu that was being taken over first by a genetically morphed dog and then a dog that ate his owner after months of being left with his brother and friends.

Ginga Densetsu Weed never had any english dubs probably because of too much violence.
