Sam Ronson's Dog Banned from West Hollywood After Dog Killing

Sam Ronson's problem child Lindsay Lohan Cadillac has been banned from West Hollywood, the scene of the crime.

Cadillac killed a dog in Ronson's condo building last August. 

As we first reported, the Department of Animal Control investigated the incident and there was talk of destroying Cadillac.  We're told the dog was sent back East but returned to Sam, who now lives with Cadillac in Venice, CA , a beach community in L.A.

But Cadillac is dogsona non grata in WeHo and, according to documents obtained by TMZ, the city declaring the pooch a "dangerous dog." 

A WeHo spokesperson tells TMZ, "The dog has been permanently removed from our City."
