The owner reported that the right swelling had been present for several
months and that it was reducible. The animal had normal urination,
behaviour and appetite, but experienced weight loss. The horse did not
manifest any of the other characteristic signs reported in the
literature, such as chronic constipation, tenesmus and difficulty in
urination. There was no evidence of severe dehydration or infection. The
mare was aged, and had foaled four times. In addition, according to the
Caslick Index, she also had a poor vulvar conformation (Figure 3).
All
these factors can lead to perineal muscle weakness. This situation could
predispose to herniation.
