I was reading another persons question to you regarding this subject. I have a dacshund who is now 5 years old who had seizures frequently.My vet mentioned some medication to me if they continued.After she had a couple more I noticed she was only having them if I had potporri burning, Glade plug-ins or the such.I discontinued using these products and she hasn't had one since.My vet thought this was interesting that I narrowed it down and thought maybe you might to.I am sure my dog isn't the only one that reacts this way to these type of products and might not need medication when we are causing them.
Do you have scientific evidence that can proove this?? If so then you should call the companies that you mentioned above and tell them that they were causing your pet to seizure. Good luck, vetcare
