Case Description- Among the patients which referred to our hospital during one year with parvoviral gastroenteritis, intussusception was diagnosed in three dogs. First dog was two month-old, male, Great Dane, second dog was three month-old, male, crossed breed, third dog was seven month-old, female, crossed breed which referred. Clinical Findings- In clinical examination depression, dehydration, weight loss, vomiting, dyschezia, tenesmus, rectal prolapse and haematochezia were revealed. The cause of enteritis was considered to be parvoviral gastroenteritis since canine parvoviral antigen (CPV-2) by kit (Quicking CPV Ag Rapid Test Kit, Model No. W81006, China) was detected. Abdominal radiography and abdominal ultrasonography were performed on the patients that were suspected of having intussusception. Thereafter they referred to surgery department for treatment. Treatment and Outcome- First patient died under general anaesthesia due to severity of systemic disease. Second patient surgery was successful and he recovered completely. Third patient died one day after surgery due to systemic disease and complications. Clinical Relevance- Intussusception is a type of intestinal obstruction that is created by the forceful invagination of one part of the intestine into the lumen of an adjacent segment and affects mainly young animals. The exact pathophysiology of the intussusception still remains unclear. It may begin as a result of a local intestinal incongruency in homogeneity (induration, acidity or sudden anatomic change in diameter) or a mechanical linkage of nonadjacent intestinal segments, which leads to a kink or a fold in the bowel wall. Intussusception has been reported to occur as a sequel to a number of conditions such as intestinal parasitism, linear foreign bodies, non-specific gastroenteritis, viral-induced enteritis (parvovirus, distemper), leptospirosis, intraluminal masses and prior abdominal surgery. Treatment of intussusception in dogs is by laparotomy and manual reduction or resection and anastomosis of the affected intestinal segment. Intussusception associated with systemic disease (e.g. acute viral enteritis or gastroenteritis) has an increased morbidity and mortality. In this case serial report, an attempt has been made to demonstrate that acute enteritis or gastroenteritis is the most likely predisposing factor for the intestinal intussusception in young dogs. It must be noticed that it is a severe pathologic life-threatening condition if diagnosis and surgical correction was postponed.
