In no particular order, here are a bunch of neat papers and links on feral dogs.

The ecology and behavior of feral dogs: A case study from central Italy, Boitani (from the Serpell book The Domestic Dog)

From the same book as above, Variation in dog society: between resource dispersion and social flux won't regret the book. I don't have an electronic copy of this.

Age-graded dominance hierarchies and social tolerance in packs of free-ranging dogs

Feral dogs of the Galapagos This talks a lot about variables to consider, such as the effects of climate and food supply on the phenotype, and on the social and hunting behavior of the dogs.

More on the Galapagos dogs, including their eradication with 1080 laced baits, as is done to Australian dingoes. It's worth noting that these are recently introduced dogs, being culled to protect unique native wildlife... As opposed to the ecosystem's apex predator being destroyed to protect livestock.

Nice overview of INdogs, the behaviour of street dogs in India.

Here is a book simply titled "Street Dogs", by Traer Scott, with lots of photos of the strays of Puerto Rico (Satos) and Mexico, . For those who can't find the book, here are two very short excerpts: one at Dead Dog Beach and also a rescue attempt in Mexico.

Some takeaways are that dogs are impressively adaptable and flexible animals. Whether or not they 'pack up' depends on things like their food supply and environmental pressures. Owned dogs, and dogs living directly off human support, may or may not form cohesive packs. They aren't required to for hunting, but often do simply because of the highly social nature of dogs. (A few people every year in the US are killed by packs of owned dogs, especially in the Southwest and/or on reservations. Ferals, though, are usually too afraid to approach a human.) Like coyotes and dingoes, ferals can and do pack up to hunt larger game. Multigenerational ferals tend to develop better social skills and cooperative groups. However, pup mortality is still very high, as they are less hardy than wild canids and domestication also took a degenerative toll on their parenting skills. Packs in rural areas can have quite a range, sometimes comparable to that of wild wolves.
