Is there a known aggressive dog living in one of MSR rentals? On the MSR website it states clearly no, "Pitbull Terrier" dogs allowed. It means absolutely nothing. LIE. It is posted for legal purposes only to protect MSR. We live 2 doors from an MSR property whose owners have a pitbull that has already attacked a dog in our neighborhood. I talked directly to the MSR attorney who was receiving all info about the attack. She was worthless. MSR will do nothing about aggressive dogs EVEN IF THEY HAVE ALREADY ATTACKED. MSR will just sit on their hands and wait for a lawsuit after your kid is mauled or dog killed. Main Street Renewal is a grotesque picture of big business.
