Interesting...Yesterday he was a 90lb pit bull terrier, today he’s a 45-50lb mix who was fighting with another dog in the house when the cops arrived; pending euthanasia in case they need a cast of the dog’s teeth.
Hmmm...
Further searching turned up the following photo
that seems to me to show a mix breed and indications of fighting...
