Dogs can die of bloat within several hours. Even with treatment, as many as 25-33% of dogs with GDV die. The gastric dilatation is one part of the condition and the volvulus or torsion is the second part. In bloat (dilatation), due to a number of different and sometimes unknown reasons, the stomach fills up with air and puts pressure on the other organs and diaphragm. The pressure on the diaphragm makes it difficult for the dog to breathe.
The tunnel systems were of great importance to the Viet Cong in their resistance to American forces, and played a major role in North Vietnam winning the war. The Cu Chi tunnels were built over a period of 25 years that began sometime in the late 1940s during the war against the French.
Vietnam, however, was divided at the 17th parallel. Ho Chi Minh led a communist government in the north (Democratic Republic of Vietnam) with its capital at Hanoi, and a new Republic of South Vietnam was established under President Ngo Dinh Diem, with its capital at Saigon.he VC were often supplemented by units of the Peopleâs Army of Vietnam (PAVN), more often called simply the North Vietnamese Army (NVA) by those fighting against it. Following the Tet Offensive of 1968, the NVA had to assume the major combat role because the VC was decimated during the offensive.
