There's no evidence that the guy abused the dogs, neglected, them, etc. How could a troupe of domesticated dogs do this?

Because they are dogs?! Domesticated dogs, of every kind, can become a pack. My uncle raised cattle in the mid-west, about 50 miles south of a very large city, where people would dump their dogs in the countryside. The dogs would form packs and would kill the cattle, so at least once a year we would have to hunt them. You name it, I saw every kind breed of dog in those packs. Believe it or not, the worst were the full sized poodles. I was shocked until I found out later that they are actually hunting animals in Europe. Dogs are smart and have very human-like behaviour but they are animals, nonetheless.
I had a river property in Echo, Oregon. It's along the Umatilla River. People who should have known better would let their dogs run, and those dogs were a terror. There was a shepherd mix, a little terrier, a black dog and a couple more - I saw different dogs at different times. We had horses and a couple of cows - and a sheep, come to think of it. Those dogs surrounded my mom once and after that it was war as far as I was concerned.
I came upon them in a circle around our mama cow and her calf; the cows were pushed back against the fence and the dogs were in a semi-circle around her, taking turns at darting in and biting at the calf. They heard my 30-30 click when I cocked it and first the black dog then the rest were gone, that fast.
I shot at one out behind our house in a couple acre open pasture; it was an aussie chasing all of my horses, including a couple of colts, in a big circle.
The neighbors who owned the big dogs said their dogs would never hurt anyone or anything, they just liked to play. The shepherd mix killed a bunch of sheep about 100 yards from my house and the other one bit a little girl in the face as she walked by their house on the way home from school. Both dogs were destroyed.
