why not humans too?
Because dogs that small wouldn't stand much (if any) chance against armed humans. Sure, if you want to sacrifice your dogs for the sake of a distraction. There's a reason why modern police, armies, and security forces don't use dogs that small. Nor did ancient armies.

The Early Roman Empire conquered Greece in 146 B.C. Roman soldiers were intrigued by the Molossus Hounds and took some of them back to Italy when they returned home.
They crossed this newfound breed with native Italian dog breeds and created their own war dogs.
These fearless canines are direct ancestors of the Cane Corso and eventually the later developed Neapolitan Mastiff as well.
Polybius, a Greek historian, reported that these war dogs were used by the Roman army to push enemies back on the front lines. They called these dogs the Canis Molossus.
They were sent charging towards calvary with flaming buckets of oil on their backs. The dogs would run under the horses and cause them to throw off their riders.
The Roman emperor Marcus Aurelius was possibly the first to formally employ the Canis Molossus in legionary warfare. The dogs were equipped with spiked protective collars and mail armour as well as chest plates.
They were even trained to run in attack formations.
They are credited for their role in helping secure many Roman victories in battle and even then were renowned for their extremely protective demeanour.
Pay particular attention to this bit:

Mail armour as well as chest plates, not gonna work with 30 pound dogs.
