Our dog had a cluster seizure last night (one seizure that looks like multiple smaller ones), which is the first seizure she's ever had. Took her in to the vet, and when the blood work came back later in the day, they found that she's basically breaking down. Irregular kidney functions, liver enzymes are way up (they'd been gradually climbing as she's aged; she's been on meds for it for ~2 yrs. now), and she's anemic (body not producing enough red blood cells). The seizure was scary, and there's literally nothing you can do as an owner but try to make sure the dog isn't near a flight of stairs, or around anything else that could hurt him/her while they're having the seizure. She whimpered leading up to the onsets of the seizure. When they came, her limbs would all stiffen, she'd arch her neck, there would be some (seemingly) involuntary barking & whimpering, and she lost bowel control. The onsets wouldn't last any longer than 15-30 seconds, even though they seemed much longer. About 5-10 minutes would pass between each of the physical displays of the seizure, and she wound up having to endure 5 strong episodes of it before it passed. In all, the ordeal lasted about 30-45 min. She got her body into some really contorted & uncomfortable looking positions throughout this process, and I didn't move her out of fear of hurting her. The vet told me today that it's absolutely ok to reposition a dog on its side if it looks uncomfortably twisted up. The only caveat is a good general warning about dog seizures, which is that the dog might bite someone/something that gets near its mouth, since it has no real body control or awareness of what's happening. Always be careful with this, as a dog won't be conscious that it's biting you. She was really dazed & out of it all last night. Couldn't balance or walk well, really had a 'far away' look in her eyes. We found out that, as seizures go, hers was pretty mild. You know, for a freaking seizure. She just wasn't herself last night at all, and was completely exhausted after the seizure, which is 100% normal. She basically just slept after everything passed, which was around 8:15p or so last night. She was lethargic again today, but had her personality back & seemed as normal as one could be given the circumstances. She even had a little spring in her step when she found out she was going for a ride in the car. She had energy, albeit nervous & scared energy, at the vet, and afterward. The vet told us we need to keep her physical activity to a minimum, and that she could also have more seizures. The activity & oxygen use is what the red blood cell production can't keep up with... which is a bit ironic since taking her to the dog park during this year's spring/summer/fall completely reinvigorated her. Before the dog park, she was lethargic, getting skin rashes, & assorted other health problems probably mostly due to stress & boredom. The dog park changed that 100%, and she's been as happy as she ever has over the past 8 or so months. She's 14 years & 7 mos. old now, and she's had a great life. It's still hard to know that we'll be losing a friend in the next few months. The vet will take another look at her tomorrow to see if she has any specific liver disease, and might benefit from any medication; might be able to add a few more months onto her life. I provided the details I did in case anyone else's dog is unfortunate enough to have a seizure -- sorry I rambled. Really just wanted to vent about my dog's rough situation. She's happy, but tired. She's also still awesome, and I'm going to miss her. EDIT: added more description of what her symptoms were like during the seizure. The vet also told me that it's very important to time the seizure -- duration, and in the case of a cluster seizure, how much time passes between the visible writhing & seizing.
