Little scientific research, however, has been published on the rate at which dogs can learn to detect an odor, the variables influencing this rate, and how this rate may vary across dogs. In two experiments, we developed a procedure that allows the study of individual differences in the acquisition of an odor detection task in dogs.
The English word dog comes from Middle English dogge, from Old English docgaa "powerful dog breed". It is believed this "dog" type was so common, it eventually became the prototype of the category "hound".
German, like other European languages, has a word borrowed from the English dog which refers specifically to mastiffs. The process of birth is "whelping", from the Old English word hwelp; the modern English word "whelp" is an alternative term for puppy. An adult female is a bitch.
An adult male capable of reproduction is a stud. An adult female capable of reproduction is a brood bitch, or brood mother. Immature males or females that is, animals that are incapable of reproduction are pups or puppies.
A group of pups from the same gestation period is a litter. The father of a litter is a sire. It is possible for one litter to have multiple sires. The mother of a litter is a dam. A group of any three or more adults is a pack.
Taxonomy Inthe taxonomist Linnaeus published in his Systema Naturae the classification of species.
Canis is a Latin word meaning dog,  and under this genus he listed the dog-like carnivores including domestic dogs, wolves, and jackals.
He classified the domestic dog as Canis familiaris and on the next page as a separate species he classified the wolf as Canis lupus. Canis familiaris is used for domestic dogs, although taxonomically it should probably be synonymous with Canis lupus. Christopher Wozencraft listed under the wolf Canis lupus what he proposed to be two subspecies: Although this may stretch the subspecies concept, it retains the correct allocation of synonyms.
They also disagree with Crowther, based on the overlap between dogs and dingoes in their morphology, in their ability to easily hybridize with each other, and that they show the signs of domestication by both having a cranium of smaller capacity than their progenitor, the wolf.
Given that Canis familiaris Linnaeus, has date priority over Canis dingo Meyer,they regard the dingo as a junior taxonomic synonym for the dog Canis familiaris.
Tedford propose that the dog could be classified as Canis lupus familiaris under the Biological Species Concept because the dog can interbreed with the gray wolf Canis lupusand Canis familiaris under the Evolutionary Species Concept because the dog has commenced down a separate evolutionary pathway to the gray wolf.

It is known that the dog was the first domesticated species. Dog anatomy Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Size and weight Dogs are highly variable in height and weight.

Shades of coat colors can vary within breeds of dogs. For example, some Golden Retrievers have light, almost cream colored coats, and others may have dark, brownish shades of coat.

(Canis lupus familiaris) on a novel discrete trials odor-detection task. / Hall, Nathaniel J.; Smith. Geometric analysis of macronutrient selection in breeds of the domestic dog, Canis lupus familiaris. In the 2-choice study, dogs similarly selected a higher proportion of energy from fat in ESS than NSS (Figure 6), but in this case the proportion of protein was fixed and fat thus displaced carbohydrate.

Male and female dogs usually reach puberty between 6 and 12 months of age; however, the time that a dog actually breeds depends on many social factors, ranging from size of breed (larger dogs need more time before they are ready to breed) and level of confidence a dog . Diet selection studies were performed in adult dogs (C. lupus familiaris) of both sexes (neutered and entire) representing 5 breeds of dog from toy to giant (PAP, MS, COS, LR, and SB) at the WALTHAM Centre for Pet Nutrition (WCPN), Melton Mowbray, UK. Throughout each study, dogs were pair-housed in purpose-built, environmentally enriched facilities with constant access to an outdoor area where they .

The participating laboratories were asked to sequence two dog samples (one bloodstain and one hair sample) for the mitochondrial D-loop region comprised between positions 15, and 16, using suggested primers and PCR conditions, and to compare their results against a reference sequence.
