Machairodontinae
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe from the Miocene to Pleistocene living from about 16 million until about 11,000 years ago. The Machairodontinae contain many of the extinct predators commonly known as "saber-toothed cats", including the famed genus "Smilodon", as well as other cats with only minor increases in the size and length of their maxillary canines. The name means "dagger-tooth", from Greek μάχαιρα ("machaira"), dagger. Sometimes, other carnivorous mammals with elongated teeth are also called saber-toothed cats, although they do not belong to the felids.
Dog behavior
Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli. It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans and they are uniquely attuned to their behaviors. Behavioral scientists have uncovered a wide range of social-cognitive abilities in the domestic dog  The origin of the domestic dog ("Canis lupus familiaris" or "Canis familiaris") is not clear.
Separation anxiety in dogs
Separation anxiety in dogs describes a condition in which a dog exhibits distress and behavior problems when separated from its handler. Separation anxiety typically manifests within 30 minutes of departure of the handler. It is not fully understood why some dogs suffer from separation anxiety and others do not. The behavior may be secondary to an underlying medical condition. With chronic stressors in dog's lives, impairments can occur on their physiological health. Increased stress in the animal alters their hormone levels and thus decreases the animals immunity to various health problems. A visit to the veterinarian is always recommended if a dog's behavior changes suddenly.
Dog
The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of the genus "Canis" (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Their long association with humans has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species.
Animal psychopathology
Animal psychopathology is the study of mental or behavioral disorders in animals. Historically, there has been an anthropocentric tendency to emphasize the study of animal psychopathologies as models for human mental illnesses. But animal psychopathologies can, from an evolutionary point of view, be more properly regarded as non-adaptive behaviors due to some sort of a cognitive disability, emotional impairment or distress. This article provides a non-exhaustive list of animal psychopathologies. Animals in the wild appear to be relatively free from eating disorders although their body composition fluctuates depending on seasonal and reproductive cycles.
Dogs in warfare
Dogs in warfare have a long history starting in ancient times. From war dogs trained in combat to their use as scouts, sentries and trackers, their uses have been varied and some continue to exist in modern military usage. War dogs were used by the Egyptians, Greeks, Persians, Sarmatians, Baganda, Alans, Slavs, Britons, and the Romans. The Molossus dog of the Molossia region of Epirus was the strongest known to the Romans, and was specifically trained for battle. Among the Greeks and Romans, dogs served most often as sentries or patrols, though they were sometimes taken into battle. The earliest use of war dogs in a battle recorded in classical sources was by Alyattes of Lydia against the Cimmerians around 600 BC.
