The occiput in dog terms is the bump or protuberance clearly seen at the back of the skull in some breeds like the English Setter and Bloodhound. However, in other breeds it is barely perceptible. Myths in dog folklore believed that size of the occipital protuberance was somehow a measure of the dog's sense of smell.
Conformation refers solely to the externally visible details of a dog's structure and appearance, along with the dog's expected temperament, which varies for each breed or type of dog. [ 8 ] For details about contents of a breed's breed standard and what is considered good conformation for a particular breed, see the article about that specific ...
Multiple health issues are associated with runts and teacup dogs. They may suffer from hypoglycaemia (low blood sugar); hydrocephaly due to the small size of the skull; portosystemic shunts; periodontitis and gingivitis due to the small jaw leading to problems with tooth growth; tracheal collapse; degenerative mitral valve disease; luxating patella and Legg-Calvé-Perthes disease; and hypothermia.
In 2007, a study identified a gene that was proposed to be responsible for dog size. The study found a regulatory sequence next to the gene Insulin-like growth factor 1 (IGF1), which, together with the gene and regulatory sequence, "is a major contributor to body size in all small dogs." Two variants of this gene were found in large dogs ...
Coren's book presents a ranked list of breed intelligence, based on a survey of 208 dog obedience judges across North America. [10] When it was first published there was much media attention and commentary in terms of both pros [11] and cons. [12] Over the years, Coren's ranking of breeds and methodology have come to be accepted as a valid description of the differences among dog breeds in ...
An Olympic-size swimming pool holds over 2 acre-feet of water For larger volumes of liquid, one measure commonly used in the media in many countries is the Olympic-size swimming pool. [47] A 50 m × 25 m (164 ft × 82 ft) Olympic swimming pool, built to the FR3 minimum depth of 2 metres (6.6 ft) would hold 2,500 m 3 (660,000 US gal).
Thus, the "top" of a human is the head, whereas the "top" of a dog would be the back, and the "top" of a flounder may be on either the left or right side. Unique terms are also used to describe invertebrates as well, because of their wider variety of shapes and symmetry. [3]
A study in 2013 indicated that dogs appear to recognize other dogs regardless of breed, size, or shape, and distinguish them from other animals. [ 25 ] In 2014, a study using magnetic resonance imaging demonstrated that voice-response areas exist in the brains of dogs and that they show a response pattern in the anterior temporal voice areas ...
