Movement disorder affecting Weimaraner dogs

The Neurology and Neurosurgery department of the Small Animal Hospital, University of Glasgow is interested in collecting information about a recently identified movement disorder, which affects Weimaraner dogs. The affected dogs are young puppies at the time of onset of the disease and are showing signs of episodic muscle stiffness and collapse. The signs appear to be triggered by exercise and/or excitement. The diagnostic tests done so far have failed to identify a cause for this disorder and a genetic cause is suspected. This is a very distressing condition for the animal and the owners, and medical treatment has only resulted in partial improvement of the signs.


The aims of this study are:

-        to identify Weimaraner dogs affected by the disorder

-        to gather information about the clinical signs shown by the affected dogs

-        to gather pedigree information from the affected dogs to determine whether there is an underlying genetic cause,

-        to potentially identify the gene(s) responsible of this disease so that a genetic test can be developed to eradicate the disease.

If you have (or had) a Weimaraner, who presented signs of episodic muscle stiffness/weakness/collapse triggered by exercise or excitement, we would like to hear from you.

This survey should only take 10 minutes of your time and could potentially help pets suffering from this condition. All data collected will be securely stored and will only be accessed by the investigators of the study. Your information will not be transmitted to any third party. By completing the online questionnaire, you consent to participate in the study. You can withdraw at all time from the study by closing your browser before the end of the questionnaire. You can withdraw from the study at any time by sending the investigators an email or a letter at the address below.


If you would like to help us even further, you will also be given the opportunity to provide the pedigree of your animal if (s)he is/was registered to the Kennel Club and a video footage of the episodes if possible. If your animal is still alive, we will also ask you whether you would agree to collect DNA samples from your animal to allow us the opportunity to characterize any underlying genetic defect. This will be done by using cheek swabs, which are a painless way to collect DNA samples. The swabs will be sent to you with a detailed instruction for use. All postage fees will be paid.


Please do not hesitate to contact us if you would require further clarification about the objectives of the study or if you have any comment or question about the questionnaire itself. You can contact us by letter at the address below or by email at


Thanks again for your help. We hope this study will contribute to Weimaraner welfare and quality of life.
