Hi have a 2 year old lurcher bitch who has epilepsy. She is currently taking pexion and phenoleptil. She has had a brain scan and her her brain was fine also her spinal fluids were fume. She has been having seizures since approx 11 months. Will using a flashing collar on her or my other three dogs cause her to have a seizure?

Young dogs sometimes suffer from what we call idiopathic seizures (cause unknown) and older dogs that have never had a seizure before, can suffer from a brain tumor causing seizures. You should keep a diary of the seizures: situation that triggers it, time start, time ends, what the seizure looks like. If the seizure lasts more than 4-5 minutes your dog needs to see a vet right away, as this can cause hyperthermia and damage the brain. If you can you should take a little video of one such seizure to take with you to the vet and show him. I suppose you could try putting a flashing collar on one of the dogs and observe your dog. If it appears that it triggers a seizure, you know that you cannot use it. If no seizures are triggered, then all is ok with using the flashing collar.
