Pituitary Dwarfism

Dear Colleagues!

Pituitary dwarfism is hereditary endocrine condition which can affect German Shepherd dogs.

This disease is caused by a genetic defect that results in the degeneration of the pituitary gland and thus in a decrease of the growth hormone level.

dwarfism GSH 02The defect has already been investigated and we would like now to obtain more data concerning the disease pattern. Almost no information exists concerning the survival time of affected dogs, if they were treated and which treatment had been chosen and at last their cause of death. Until a few years ago it was very difficult to definitely diagnose pituitary dwarfism, because access to the measurement of canine growth hormone was limited. Often it was only a suspected diagnosis based on the dog´s appearance. Nowadays a genetic test has been developed that also identifies genetic carriers.

In order to get an overview of the questions raised above, we are looking for German Shepherd dogs that are affected by dwarfism. We have designed a survey which is directed to owners of affected dogs. It is available online: Click HERE

It would be very valuable if this questionnaire could be forwarded to and filled in by owners of affected dogs. Any participation in this survey will be very much appreciated.

Of course all data will be confidential and we will not reveal any pet names or personal details. We would like to use only the scientific data collected.
