Canine reproductionCanine reproduction is the process of sexual reproduction in domestic dogs, wolves, coyotes and other canine species. As with all mammals, a dog's penis is made up of three pieces of erectile tissue. These are the two corpora cavernosa and the singular corpus spongiosum which continues in the glans. A notable difference from the human penis is that the visible part during an erection consists entirely of the glans. The Retractor muscle is attached at the shaft of the penis.
Fur clothingFur clothing is clothing made from the preserved skins of mammals. Fur is one of the oldest forms of clothing, and is thought to have been widely used by people for at least 120,000 years. The term 'fur' is often used to refer to a specific item of clothing such as a coat, wrap, or shawl made from the fur of animals. Humans wear fur garments to protect them from cold climates and wind chill, but documented evidence of fur as a marker of social status as far back as 2,000-years ago with ancient Egyptian emperors and high priests wearing the skins of leopards.
AlborzThe Alborz ( البرز) range, also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the smaller Aladagh Mountains and borders in the northeast on the parallel mountain ridge Kopet Dag in the northern parts of Khorasan. All these mountains are part of the much larger Alpide belt. This mountain range is divided into the Western, Central, and Eastern Alborz Mountains.
Roe deerThe roe deer (Capreolus capreolus), also known as the roe, western roe deer, or European roe deer, is a species of deer. The male of the species is sometimes referred to as a roebuck. The roe is a small deer, reddish and grey-brown, and well-adapted to cold environments. The species is widespread in Europe, from the Mediterranean to Scandinavia, from Scotland to the Caucasus, and east as far as northern Iran. The English roe is from the Old English rā or rāha, from Proto-Germanic *raihô, cognate with Old Norse rá, Old Saxon rēho, Middle Dutch and Dutch ree, Old High German rēh, rēho, rēia, German Reh.
Dirofilaria immitisDirofilaria immitis, also known as heartworm or dog heartworm, is a parasitic roundworm that is a type of filarial worm, a small thread-like worm, that causes dirofilariasis. It is spread from host to host through the bites of mosquitoes. There are four genera of mosquitoes that transmit dirofilariasis, Aedes, Culex, Anopheles, and Mansonia. The definitive host is the dog, but it can also infect cats, wolves, coyotes, jackals, foxes, ferrets, bears, seals, sea lions and, under rare circumstances, humans.
Ancylostoma caninumAncylostoma caninum is a species of nematode known as a hookworm, which principally infects the small intestine of dogs. The result of A. caninum infection ranges from asymptomatic cases to death of the dog; better nourishment, increasing age, prior A. caninum exposure, or vaccination are all linked to improved survival. Other hosts include carnivores such as wolves, foxes, and cats, with a small number of cases having been reported in humans. Warm and moist conditions are important to allow survival of A.
