Dog Anatomy ... All dogs (and all living Canidae) have a ligament connecting the spinous process of their first thoracic (or chest) vertebrae to the back of the axis bone (second cervical or neck bone), which supports the weight of the head without active muscle exertion, thus saving energy... This ligament allows dogs to carry their heads while running long distances, such as while following scent trails with their nose to the ground, without expending much energy...
Neutering ... Prevention of mammary tumors: Female cats and dogs are about seven times less likely to develop mammary tumors if they are spayed before their first heat cycle... Female dogs that have been spayed before their first heat have a lifetime chance of developing mammary tumors of about 99.5% less than that of intact females... Also, spaying female dogs more than two years before the removal of mammary tumors increases the dog's survival odds by 45%...
Wolves In Ireland ... The Morrígan was said to take on the form of a red-furred wolf, particularly in her battle with the hero Cú Chulainn. Mac Cecht killed a wolf feeding on a still living woman on a battlefield...

Pet ... In many locations, animals that are considered pets by their owners but are legally classified as livestock, including horses, pigs, camelids, and fowl may be banned from being kept within the city limits or restricted to property of a certain larger size. The cities of Berkeley, California, and Boulder, Colorado, have passed laws stating that people who have pets do not "own" them; rather, they are the pet's "guardian."...
Wolfdog ... In first generation hybrids, gray wolves are most often crossed with wolf-like dogs (such as German Shepherds, Siberian Huskies, and Alaskan Malamutes) for an appearance most appealing to owners desiring to own an exotic pet... Horand became the centre-point of the breeding programs and was bred with dogs belonging to other society members that displayed desirable traits... New World Black Wolves Genetic research from the Stanford University School of Medicine and the University of California, Los Angeles revealed that wolves with black pelts owe their distinctive coloration to a mutation that first arose in domestic dogs...
Bloat ... Causes Bloat in dogs is likely caused by a multitude of factors, but in all cases the immediate prerequisite is a dysfunction of the sphincter between the esophagus and stomach and an obstruction of outflow through the pylorus,or a clog... Studies have indicated that the risk of bloat in dogs perceived as happy by their owners is decreased, and increased in dogs perceived as fearful... This may be due to the physiological effects of the dog's personality on the function and motility of the gastrointestinal system.; alternatively perhaps the dogs become unhappy/uncomfortable as a consequence of the conditions that lead up to exhibiting bloat...
Origin Of The Domestic Dog ... Due to the difficulty in assessing the structural differences in bones, the identification of a domestic dog based on cultural evidence is of special value. Perhaps the earliest clear evidence for this domestication is the first dog found buried together with human from 12,000 years ago in Palestine and a burial site in Germany called Bonn-Oberkassel with joint human and dog interments dating to 14,000 years ago...
Canine Reproduction ... Most dogs come into season for the first time between 6 and 12 months, although some larger breeds delay until as late as 2 years...

California Assembly Act AB 1634 was a bill introduced in 2007 that would require all non-working dogs of mixed breed over the age of 6 months to be neutered or spayed... The clear genetic distinction between breeds of dog has made dogs of specific breeds good subjects for genetic and human medical research...
Cat ... Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. As crepuscular predators, cats use their acute hearing and ability to see in near darkness to locate prey...
Purebred ... A puppy from two purebred dogs of the same breed, for example, will exhibit the traits of its parents, and not the traits of all breeds in the subject breed's ancestry...
Gray Wolf ... Though once abundant over much of Eurasia, North Africa and North America, the gray wolf inhabits a reduced portion of its former range due to widespread destruction of its territory, human encroachment, and the resulting human-wolf encounters that sparked broad extirpation. Today, wolves are protected in some areas, hunted for sport in others, or may be subject to population control or extermination as threats to livestock, people, and pets...
Breed Registry ... Kennel clubs always maintain registries, either directly or through affiliated dog breed clubs. Some multi-breed clubs also maintain registries, as do non-affiliated breed clubs, and there are a few registries that are maintained by other private entities such as insurance agencies; an example of this in the United States is the Field Dog Stud Book...
Subspecies Of Canis Lupus ... Canis lupus is assessed as Least Concern by the IUCN, as its relatively widespread range and stable population trend mean that the species, at global level, does not meet, or nearly meet, any of the criteria for the threatened categories. However, some local populations are classified as Endangered, and some subspecies are endangered or extinct...
Miniature Horse ... Miniature horses are friendly and interact well with people. For this reason they are often kept as family pets, though they still retain natural horse behavior, including a natural fight or flight instinct, and must be treated like an equine, even if they primarily serve as a companion animal...
Cat Senses ... Many cats have a visual field of view estimated at 200°, versus 180° in humans, with a binocular field (overlap in the images from each eye) narrower than that of humans. As with most predators, their eyes face forward, affording depth perception at the expense of field of view...
