my very first newf puppy developed seizures right around the 1.5 to 2 year mark. It got so bad we had to put her down in about 8 months after her first seizure appeared. Hers went from one to one or more every day. And they increased in the severity too. Her last one literally flung her across the rug, how bad she was convulsing. I suspected it was the flea and tick stuff we used on her right before that first seizure!
We tried phenobarb and valium. We also used Rescue Remedy which actually helped decrease the severity of the seizure if we got it in her during the pre-ictal stage (pre-ictal is before the seizure) there are three stages to a seizure..pre-ictal, seizure, and post ictal. There are different types of canine seizures...just like there are different types for humans. You dog seems to be exhibiting sensory motor seizures..still congnitive enough to be able to communicate on some very primal levels and reacts awkwardly to communications directed at him. Trust me..they are really all the same in the end.
I strongly suggest you join some canine epi lists. They were incredibly supportive and educational. No one knows what it is like living with an epi dog until they do so on their own.
I would suggest not crating an epi dog. When they thrash, their legs can become caught in and broken in the wires.
dog drooling and frothing is common during a seizure
in the post ictal stage, they usually are drowsy, "off", confused...ours was very thirsty and hungry...we fed her vanilla ice cream because it was cooling to her tongue that she had bitten up...ours paced and paced and paced until she would collapse
we provided comfort but allowed her to go thru her stages without interference, save for the rescue remedy and anything we needed to do to keep her safe.
we put her down finally as an act of mercy. She was dragging her back legs even out of a seizure and was confused and cloudy even when she was not in seizure. It was the hardest euthenasia I ever had to do. THe monster that lived inside her took my beloved Bella from me. I laid her to rest so she could be rid of it...
