The Secret Service is so dumb they can’t get their breeds straight. The black colored one is a German shepherd.
Not to be a wet blanket but I have questions about their dog handling. It appeared they kept the dogs on leash which penalizes the dogs and restricts their movements. After checking with some K9 handlers I knew from NAM they concurred that that would not be the best thing for the dogs and they are more likely to get injured when restrained during an attack.
