Symptoms of both types include vomiting, loss of appetite, depression, and increased drinking and urinating. Fever is seen in less than a third of female dogs with<unk> . Closed<unk>  is a more serious condition than open<unk>  not only because there is no outlet for the infection, but also because a diagnosis of closed<unk>  can easily be missed due to its insidious nature. Bloodwork may show dehydration and/or increased white blood cell count. X-rays will show an enlarged uterus, and ultrasound will confirm the presence of a fluid filled uterus.
