Beth, that is the type of seizures my heart grey, Pepsi used to have. Her final one was on Aug.08/04. She began to seize at 2:30 AM and would not come out of it except when she was walked. I believe that she couldn't see by then, as when Mike walked her, she couldn't find me unless I called her name. At 3:30 that afternoon, friends drove us up to the Evet in Fort Worth. Pepsi seized the entire time in the truck and had exactly the same expression on her face (teeth bared) as Steak does.
When we got there, as Mike lifted her out of the back seat, she lost control of her bowels. The vet put her on a Valium IV and said that when she came off it, she could be the same or be OK, and of course, this could recur anytime. As she palpated Pepsi's stomach, she yelped. I made the decision right then and held her in my lap as she crossed the bridge. I just couldn't let her continue seizing.
I just went back and read the entire thread - please, do not feel bad about the decisions you have made - you made them based on many circumstances that you have no control over. BTW, Mike takes Keppra for his seizures caused by his brain tumors. The oncologist says it is better than Delantin BUT they need to watch his organs, as it can be hard on them. Has the vet mentioned this to you?
I feel so much for you as you go through this.
