German Shepherd Pituitary Dwarfism Study

February 19, 2017

Dear Colleagues!

Pituitary dwarfism is hereditary endocrine condition that can affect German Shepherd dogs (GSH). 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.

The defect in the GSH population 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.
In order to get an overview of the questions raised above, we are looking for German Shepherd dogs that are affected by dwarfism and unaffected GSD that act as controls (both can be alive or deceased). We have designed a survey which is directed to owners of affected dogs, but can also be filled in by veterinarians if the owner is unavailable or does not want to participate. It is available online:

It would be very valuable if this questionnaire could be forwarded to owners of GSH with pituitary dwarfism and unaffected DSH 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.

We would be very grateful if you could support this project. Please do not hesitate to contact us if you have questions or concerns.
