It is difficult to identify dogs with Hyperplasia because it only becomes visible when the dog is on heat and not always the first heat that occurs but only sometimes at a later stage. Hyperplasia manifests in some bitches as a bulging of the uterus. In some bitches it is not physically discernible. Should tests indicate the presence of the Hyperplasia, the breeder has to decide whether to discontinue breeding with the animal or not. A number of experts maintain that the problem should be graded, as is the case with hip displasia, and that breeders should be allowed to breed with bitches that do not suffer from serious hyperplasia.
