Study Notes
Dog Characteristics and Evolution
- Dogs are domestic mammals of the Canidae family, order Carnivora. Their scientific name is Canis lupus familiaris.
- They are a subspecies of the gray wolf (Canis lupus) and related to foxes and jackals.
- Dogs are one of the two most common and popular domestic animals.
- Dogs' sizes range significantly, from the small Chihuahua (5-8 inches) to the large Irish Wolfhound (30+ inches).
- Dogs' roles and value vary across cultures.
- Dogs' roles range from hunting companions and protectors to beasts of burden, guards, and even food in certain parts of the world; in other areas, they are highly valued.
Dog Communication and Behaviour
- Dogs bark to communicate with other dogs and humans.
- Barking can signal territoriality, threat, or a desire for attention.
- Sniffing other dogs' rear ends helps dogs gather chemical information regarding identity, genetics, reproductive status, diet, and emotional state.
- Specialized scent glands on either side of their anus provide unique scent profiles.
Dog Health and Vaccination
- Dogs receive a series of four combined vaccines (distemper, hepatitis, parainfluenza, and parvovirus) starting at six weeks old, with booster shots at one year and then every three years.
- Dogs get a rabies vaccine at three months old, and boosters are given yearly or every three years, depending on the schedule.
Dog Ageing
- Dog years aren't a simple multiple of human years; their aging depends on size and breed.
- Small dogs typically age more slowly than large ones.
- Some breeds, like beagles, may have a different aging rate than others of a similar size.
Dog History and Origin
- Dogs evolved from the genus Miacis.
- Cynodictis was an early, true dog-like ancestor.
- Tomarctus from the Eurasian branch of Cynodictis is the progenitor of wolves, dogs, and foxes.
- Genetic evidence suggests that dogs descended from wolves.
- Domestication wasn't a single event but a process occurring thousands of years ago in northern Eurasia.
- Dogs likely facilitated their own domestication by foraging on leftover game animals.
- Early domestication events may have occurred in different regions of Eurasia, with dogs and wolves interbreeding.
- Some genetic studies suggest initial domestication events for livestock purposes in China (16,300 years ago) or with a smaller wolf strain in India (12,000-14,000 years ago).
- Dogs arrived in the Americas around 10,000 years ago, not with the first humans.
- Some African breeds might have descended from jackals, not wolves.
Canine Anatomy and Physiology
- Dogs are mammals that bear live young, and have mammary glands for suckling.
- Early dog breeds had erect ears and pointed/wedge-shaped muzzles.
- Dogs and other carnivores share similar dental structures.
- Dogs develop two sets of teeth: deciduous ("baby") and permanent.
- Dogs are homeothermic (have an internal thermostat), and walk on their toes rather than flat-footed.
Types Of Dogs (Fossil Record)
- By the Bronze Age (about 4500 BCE), five distinct types of dogs existed: mastiffs, wolf-type dogs, sight hounds (e.g., Saluki, greyhound), pointing dogs, and herding dogs.
