Mongrel (1982)

At a boarding house, a vicious dog gets loose from his chain and chews up a tenant's ass that was teasing him with a piece of raw meat. As a result, the dog is shot to death. Another tenant, a very high strung book editor, is picked on a lot. Soon he starts having dreams that the dog has returned and dead chewed up tenants begin popping up everywhere.
