Letter To The Editor: Reader IDs Dangerous Dog

Los Alamos Resident
Name Withheld By Request
I just read one of your readers account of his dangerous encounter with a vicious dog on pipeline road. I had a similar encounter with that same dog and his owner about a month ago while walking a friends dog we were watching for them while they were out of town.
I too am a dog lover and this was without a doubt the scariest encounter with a dog I’ve ever had. Fortunately the dog stopped a few feet from us as we stood our ground and the owner grabbed the leash that had been ripped out of his had once his dog spotted us. 
I know where this dog lives as the owner was in his driveway when he lost control of it. He told me it is a South African Mastive. I’m calling animal control before someone gets seriously hurt.
