A pack of dogs

A pack of dogs consisting of 9 (not counting the puppies; with the puppies, there are 12) dogs of various (and some identical) breeds. The pack includes an alpha, a beta, two hunters, and mothers with puppies.

Richard — the alpha of the pack, breed: long-haired German Shepherd. Richard's personality: aggressive toward humans, warlike, ready to defend the pack until the last drop of blood or the last breath.

Emm: a pregnant female, breed: Afghan Hound, personality: kind, polite, timid, afraid of humans.

Ford: the beta (assistant to the alpha), breed: Leonberger, personality: not particularly mean, aggressive toward humans, honest.

Bobik: an ordinary dog in the pack, breed: common mutt, personality: cheerful, clingy, energetic.

Reni: a female with three puppies, breed: White Swiss Shepherd, personality: kind, timid, afraid of humans. (Puppies: Rowan, breed: German Shepherd; Richie, breed: Russian Borzoi; Nelly, breed: long-haired German Shepherd.)

Hektar: a hunter, breed: Pit Bull Terrier, personality: aggressive, hates humans.

Schwarz: a hunter, breed: Russian Borzoi, personality: calm, kind.

Gem: just a dog in the pack, breed: long-haired German Shepherd, personality: calm, kind, polite.

Rayley: an ordinary female in the pack, breed: Spanish Galgo, personality: aggressive, hot-tempered.

Once, the pack was just wandering through the city in search of a place to spend the night. They found a spot by a fence, in a hole underneath it; there was a small cave-like space that easily fit the pack of 9 dogs and three puppies. Hm, the rest is up to you.
