Some animals can detect a sez before they come. However not all can. Had a lady I worked with has a dog that would whine then place her head on the ladies chest to let her know a sez was about to happen. Pretty amazing what animals can do for us

I have shetland sheepdogs & that cant change right now. That is why I need a source for training

Dogs can tell from the smell that you are about to have a seizure. When I had my dog she would stay by me and sleep with me. I've even had a cat that knew when I was having seizures and went to get my mother.

Normin on the left was my service dog for 9 years. He saved my butt lots of times
Pup on the left is louseal she flunked service dog training
Just remember all dogs dont pan out. Good luck
