Without humans to guide them, dogs returned to the wild. An obvious downside to dogs returning to their wild roots is that many dogs were left infertile from being spayed and neutered, this didn't hinder their survival, but it decreased the amount of contributions to the gene pool. Another problem for the now wild dogs was inbreeding caused by humans, severely inbred breeds usually had their genetic bred out by mixing with healthier breeds. The intermixing of different breeds led to endless amounts of mutt breeds and mutt packs roaming the world. Dogs didn't just interbreed with different breeds, they bred with other species and subspecies.
Diredogs
Diredogs (Canis lupus Starki) are a mix of a domestic dog and a Eurasian wolf. Diredogs may also have a combination of DNA from Italian and Himalayan wolves as well as jackals. These wolf-dogs are found in Europe and North Asia. They hunt medium-large sized animals like mowboars. Diredogs travel and hunt in packs, led by the breeding pair. Most diredogs are about the size of a pitbull. Diredogs behave similarly to normal dogs with similar forms of communication and intellect.
Cogolves
Cogolves (Canis Lupus Wilei) are a mix of a gray wolf, a domestic dog, and a coyote. They range from being the size of a husky to the size of a wolf depending on the climate. Desert Cogolves are the smallest subspecies and feast on prickly pears and small desert rodents. Plains Cogolves are the largest and feed on large herbivores. Cogolves contain the blood of Artic, red, Mexican, sea, and other subspecies of wolf depending on the area.
Cogolves are more coyote than dog because they don't hunt in packs. Instead of packhunting, Cogolves hunt in pairs, usually either scavenging or taking down smaller or weaker prey. If a Cogolf pair were to take down a larger kill, they usually team up with another pair to share their kill with. Cogolves are monogamous and never mate outside of their pairing with another Cogolf. The pups grow up and then leave to form their own pairings, unlike wolves who stay together.
Yodelers
Yodelers (Canis lupus infanscomedenti) are a mix of a dingo, a domestic dog, and a New Guinea singing dog. They are about the same size as a dingo. Genes that were previously a problem in dingo hybrids have largely been bred out, save for mostly insignificant changes like tail shape and coat coloration. Their singing dog lineage lead to yodelers losing the ability to bark and instead, as their name suggests, yodel. These calls are unique for each pack and function like an actual language rather than a few signals. More complex calls help aid Yodelers in hunting by allowing their prey to be corralled into harm's way. Yodelers hunt in packs, usually only taking down medium-sized prey or scavenging from the kills of larger predators.
Tidogs
Tidogs (Canis lupus Schreibvogeli) are a mix of African wolves and domestic dogs. They are found throughout the northern half of mainland Africa as well as the Adzanian isles. Mainland Tidogs are around the size of a Spotted Hyena while Adzanian Tidogs are around the size of a large cat. Tidogs hunt in packs and conduct group ambushes from tall grass on chevrolopes and other small-medium sized animals. Tidogs get their name from the fact that they have red stripes on their backs to help them hide in tall grass. Their red coloration comes from the fact that they have a considerable amount of Ethiopian wolf genes. Tidogs also get their long snout from Ethiopian wolves.
