Attention all SV owners and Breeders.
✨ Upcoming research: Paroxysmal Dyskinesia in Swedish Vallhunds ✨
The Specialklubben för västgötaspets in Sweden is helping coordinate a global survey on paroxysmal dyskinesia in Swedish Vallhunds, alongside genetic research being carried out by the Hannes Lohi Lab at the University of Helsinki. This disease is not exclusive to Vallhunds - it can affect dogs, cats, and humans too.
The current research has found a possible connection between dyskinesia in Swedish Vallhunds and a specific brain gene risk variant; the same gene may also be linked to general personality and behavior. A dog may have increased genetic risk and still remain healthy, so the research team needs much more information before firm conclusions can be drawn.
Paroxysmal dyskinesia is a movement disorder that can appear in sudden episodes. These episodes may look like cramping, trembling, stiffness, abnormal movements, difficulty balancing, or unusual body postures. In some dogs, episodes are very brief and easy to miss. In others, they may be more obvious. Paroxysmal dyskinesia can look similar to epilepsy, but it is not the same thing. Dogs with dyskinesia are often conscious during the episode and may return to normal afterward. Because symptoms can overlap with seizure disorders, videos of episodes and assessment by a veterinarian, ideally a neurologist, can be very helpful.
Would you like to help with the research?
1. Complete the breed club survey if you have, or have had, a Swedish Vallhund with diagnosed or suspected paroxysmal dyskinesia. There are separate forms for dogs currently living or dogs who died in 2020 or later, and dogs who died between 2005 and 2019.
2. Participate in the genetic research. The researchers are asking for blood samples from Swedish Vallhunds with dyskinesia-type episodes, Vallhunds with epilepsy, plus healthy close relatives of affected dogs. The lab is also looking for other healthy Swedish Vallhunds, especially from countries outside Finland, who seem unaffected by this disease.
3. Fill out the questionnaires! There is a questionnaire for dogs with dyskinesia or epilepsy-like episodes, and a behavior/personality questionnaire for all Swedish Vallhunds. Healthy dogs are useful to the research too and help establish a baseline for comparison, as well as possible prevalence in the breed as a whole.
4. Share this information! The study needs participation from multiple countries so the breed as a whole is represented. More reports, more samples, and more open health information can help researchers better understand what is happening and support the long-term health of the Swedish Vallhund.
More information about the project can be found at the link below, and questions about the genetic research can be sent to the University of Helsinki research team via contact details found there too:

Not sure how to recognize what seizures can look like in different individuals? The research team has provided some videos of Vallhunds being affected:

Transparency about the health of dogs is the foundation for the future of the breed. It is therefore important that everyone, both breeders and dog owners, who has or have had a dog with seizures participates in reporting.
