Structural follicular dysplasia varies by breed but all involve weakened hairs that break easily. Hair loss is originally seen in areas of repeated grooming or trauma, for instance the neck because of contact with a collar.
Research indicates that the majority of variation in coat growth pattern, length and curl can be attributed to mutations in four genes, the R-spondin-2 gene or RSPO2, the fibroblast growth factor-5 gene or FGF5, the keratin-71 gene or KRT71 [15] and the melanocortin 5 receptor gene (MC5R). The wild-type coat in dogs is short, double and straight.
The Great Dane was named the state dog of Pennsylvania in 1965 [42] and the University of Iowa had Great Danes, Rex I and Rex II, as mascots before the Hawkeye was chosen. [43] "Great Danes" is the nickname of the University at Albany. Their mascot is the Great Dane. [44] Military. Just Nuisance was the only dog to be officially enlisted in the ...
Often mistaken for a "double merle", a harlequin merle (or just harlequin), is a Great Dane that carries both the merle pattern allele and the co-dominant modifying gene for harlequin, PSMB7 (also known as H). This causes most or all of the diluted "blue" color to be replaced with white, resulting in a dog that is mostly white with black patches.
A great Dane, who has been described by his family as a “gentle giant”, has achieved the Guinness World Record (GWR) for the world’s tallest dog living (male).
A 135lbs Great Dane and a 10lbs ginger kitty = true love! Wish I was the proud owner of these two bffs, but these cuties belong to my older sister. I just get the honor of witnessing their heart ...
Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes, e.g., leg length in dogs) or discrete traits (traits that fall into discrete categories and are coded for by one or a few genes, e.g., white, pink, or red petal color ...
A Great Dane with the brindle color pattern. Brindle is a coat coloring pattern in animals, particularly dogs, cattle, guinea pigs, cats, and, rarely, horses. It is sometimes described as "tiger-striped", although the brindle pattern is more subtle than that of a tiger's coat. Brindle typically appears as black stripes on a red base.
