Coyote Puppy Saved From Dangerous Cactus

The coyote, also known as the American jackal, brush wolf, or the prairie wolf, is a species of canine found throughout North and Central America, from Panamain the south, north through Mexico, the United States, and Canada. It occurs as far north as Alaska and all but the northernmost portions of Canada.

Currently, there are 19 subspecies, with 16 in Canada, Mexico, and the United States, and three in Central America. Unlike the related gray wolf, which is Eurasian in origin, evolutionary theory suggests the coyote evolved in North America during the Pleistocene epoch 1.81 million years ago (mya) alongside the dire wolf. Although not closely related, the coyote evolved separately to fill roughly the same ecological niche in the Americas that is filled in Eurasia and Africa by the similarly sized jackals. Unlike the wolf, the coyote’s range has expanded in the wake of human civilization, and coyotes readily reproduce in metropolitan areas.

The name “coyote” is borrowed from Mexican Spanish coyote, ultimately derived from the Aztec word cóyotl, meaning “trickster”. Its scientific name, Canis latrans, means “barking dog” in Latin. Female coyotes are monoestrous, and remain in estrus for two to five days between late January and early March, during which mating occurs. Once the female chooses a partner, the mated pairmay remain temporarily monogamous for a number of years. Depending on geographic location, spermatogenesis in males takes around 54 days, and occurs between January and February.

Dog is the common use term that refers to members of the subspecies Canis lupus familiaris (canis, “dog”; lupus, “wolf”; familiaris, “of a household” or “domestic”). The term can also be used to refer to a wider range of related species, such as the members of the genus Canis, or “true dogs”, including the wolf, coyote, and jackals; or it can refer to the members of the subfamily Caninae, which would also include theAfrican wild dog; or it can be used to refer to any member of the family Canidae, which would also include the foxes, bush dog, raccoon dog, and others. Some members of the family have “dog” in their common names, such as the raccoon dog and the African wild dog. A few animals have “dog” in their common names but are not canids, such as the prairie dog.
The English word dog comes from Middle English dogge, from Old English docga, a “powerful dog breed”. The term may derive from Proto-Germanic *dukkōn, represented in Old English finger-docce (“finger-muscle”). The word also shows the familiar petname diminutive -ga also seen in frogga “frog”, picga “pig”, stagga “stag”,wicga “beetle, worm”, among others. Due to the archaic structure of the word, the term dog may ultimately derive from the earliest layer of Proto-Indo-European vocabulary, reflecting the role of the dog as the earliest domesticated animal.
