Aging In Dogs
Aging in dogs varies from breed to breed, and affects the dog's health and physical ability. As with humans, advanced years often bring changes in a dog's ability to hear, see, and move about easily. Skin condition, appetite, and energy levels often degrade with geriatric age. Medical conditions such as cancer, kidney failure, arthritis, dementia, and joint conditions, and other signs of old age may appear. The aging profile of dogs varies according to their adult size (often determined by their dog breed, breed): smaller breeds have an average lifespan of 10–15 years, with some even exceeding 18 years in age; medium breeds typically live for 10 to 13 years; and giant dog breeds have the lowest minimum lifespan, with an overall average of 8 to 13 years. The latter reach maturity at a slightly older age than smaller breeds, with giant breeds reaching adulthood at around two years old compared to the norm of around 13–15 months for other breeds. The accelerated rate of growth re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10 Yr Old Mastiff
1 (one, unit, unity) is a number, Numeral (linguistics), numeral, and glyph. It is the first and smallest Positive number, positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit (measurement), unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In Digital electronics, digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In math ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Shepherd Dog
The German Shepherd, also known in Britain as an Alsatian, is a German breed of working dog of medium to large size. The breed was developed by Max von Stephanitz using various traditional German herding dogs from 1899. It was originally bred as a herding dog, for herding sheep. It has since been used in many other types of work, including disability assistance, search-and-rescue, police work, and warfare. It is commonly kept as a companion dog, and according to the Fédération Cynologique Internationale had the second-highest number of annual registrations in 2013. History During the 1890s, attempts were being made to standardise dog breeds. Dogs were being bred to preserve traits that assisted in their job of herding sheep and protecting their flocks from predators. In Germany this was practised within local communities, where shepherds selected and bred dogs. It was recognised that the breed had the necessary skills for herding sheep, such as intelligence, spee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lancashire Heeler
The Lancashire Heeler is a small breed of dog developed for use as a drover and herder of cattle. The Lancashire Heeler is listed by the Kennel Club (UK) as an endangered breed. The breed was recognized by the American Kennel Club in 2024. Description The dog's coat is harsh and smooth with an undercoat which keeps the dog dry in all weathers. It may have a slight mane around the neck in winter. The dog is usually black and tan, but liver and tan is also recognised by the Kennel Club. They are slightly longer than height at withers, usually measures between at the shoulder and weighs . In terms of personality, the breed standard used by the American Kennel Club describes them as "courageous, happy," and "affectionate to owner". When happy, Lancashire Heelers may part their lips to mimic a human smile. Health A 2024 UK study found a life expectancy of 15.4 years —the highest in the study— for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreed ...

Scientific Reports
''Scientific Reports'' is a peer-reviewed open-access scientific mega journal published by Nature Portfolio, covering all areas of the natural sciences. The journal was established in 2011. The journal states that their aim is to assess solely the scientific validity of a submitted paper, rather than its perceived importance, significance, or impact. In September 2016, the journal became the largest in the world by number of articles, overtaking '' PLOS ONE''. Abstracting and indexing The journal is abstracted and indexed in the Chemical Abstracts Service, the Science Citation Index Expanded, and selectively in Index Medicus/MEDLINE/PubMed. According to the ''Journal Citation Reports'', the journal has a 2023 impact factor 3.8. Reviewing policy The ''Guide to Referees'' states that to be published, "a paper must be scientifically valid and technically sound in methodology and analysis", and reviewers have to ensure manuscripts "are not assessed based on their perceived impor ...

Mutt (dog)
A mongrel, mutt, or mixed-breed dog is a dog that does not belong to one officially recognized breed, including those that result from intentional breeding. Although the term ''mixed-breed dog'' is sometimes preferred, many mongrels have no known purebred ancestors. Crossbreed dogs, and " designer dogs", while also a mix of breeds, differ from mongrels in being intentionally bred. At other times, the word ''mongrel'' has been applied to informally purpose-bred dogs such as curs, which were created at least in part from mongrels, especially if the breed is not officially recognized. Although mongrels are viewed as of less commercial value than intentionally bred dogs, they are thought to be less susceptible to genetic health problems associated with inbreeding (based on the theory of heterosis), and have enthusiasts and defenders who prefer them to intentionally bred dogs. Estimates place the prevalence of mongrels at 150 million animals worldwide. Terminology Mixed-breed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Standard Deviation
In statistics, the standard deviation is a measure of the amount of variation of the values of a variable about its Expected value, mean. A low standard Deviation (statistics), deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. The standard deviation is commonly used in the determination of what constitutes an outlier and what does not. Standard deviation may be abbreviated SD or std dev, and is most commonly represented in mathematical texts and equations by the lowercase Greek alphabet, Greek letter Sigma, σ (sigma), for the population standard deviation, or the Latin script, Latin letter ''s'', for the sample standard deviation. The standard deviation of a random variable, Sample (statistics), sample, statistical population, data set, or probability distribution is the square root of its variance. (For a finite population, v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Cattle Dog
The Australian Cattle Dog, or simply Cattle Dog, is a breed of herding dog developed in Australia for droving cattle over long distances across rough terrain. This breed is a medium-sized, short-Coat (dog), coated dog that occurs in two main colour forms. It has either red or black hair distributed fairly evenly through a white Coat (dog), coat, which gives the appearance of a "red" or "blue" dog. As with dogs from other working dog, working breeds, the Australian Cattle Dog is energetic and intelligent with an independent streak. It responds well to structured training, particularly if it is interesting and challenging. It was originally bred to herd by biting, and is known to nip running children. It forms a strong attachment to its owners, and can be protective of them and their possessions. It is easy to groom and maintain, requiring little more than brushing during the shedding period. The most common health problems are deafness and progressive blindness (both Heredity, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
