While we humans are quite comfortable translating this type of "double
talk", it might surprise you to know that dogs also recognize double words,
such as "sit-sit", "down-down" and "come-come". Some dogs are even capable
of understanding "three-peats" such as "sit-sit-sit" or "stay-stay-STAY!!!"

One of the most common training errors is repeating commands. If Fido does not "sit" at the first command, we automatically say the word again ("sit-sit"). Over a series of repetitions, we inadvertently teach the dog to wait patiently until the second or third command before he is required to respond. While the owner fumes about stubbornness and laziness, the dog's comment would probably be, "Look , boss, the command isn't "sit", it" is "sit-sit!" I'm just waiting for you to finish the sentence!" The ironic part of this exchange is that both participants are convinced the other is mistaken.
