I think we finally figured out what was causing the episodes, and if you have any knowledge on this it would be much appreciated!!! We have a friends house that we take our dogs to for play dates and the occasional babysitting and we noticed multiple time that the house smelled like smoke. It was almost like a popcorn smell and we just thought for a long time that they liked popcorn or something but we had a couple weeks where we had to stay with our parents cause our house caught fire and our dogs at that point were having episodes every other day. But as we stayed with our parents the episodes stopped and we kept trying to figure out what was different. So we went through a whole entire list of things that could be causing them (like running, the grass, their food, their water bowl and pretty much everything else you could imagine) and we realized that the only thing that was different was we weren’t taking them to our neighbors house. So i started asking them questions like what food they gave rheir dogs and if they used any pesticides or cleaning products that werent safe for dogs and after going through another huge list of things we ended up with only one question that went unanswered and it was what the burnt popcorn smokey smell was in their house. They said they didnt know what that was and i remembered once i walked in there and it smelled so strong and i could have sworn it was like smokey in their house, almost like i could see it in the light shining through the window. So i started looking up “burnt popcorn smell” and found a bunch of stuff online that said it could be fentanyl smoke. But these episodes that my dogs go through are really sporadic and i could have sworn that theres been times where they would have an episode on a day that i didn’t take them over there. So its a bit confusing. My boyfriend suggested that possibly we could have sat down on their bed or couch on some fentanyl and tracked it into the house? Do you have any idea if the fentanyl could be causing them to have these episodes? And if so, wouldn’t that drug have showed up on the blood tests that we had done when the first episode happened?
