Amy, Snoopy is on 500 mg tablets of Keppra twice aday. The price doesn't seem to be much different in Canada.

I waited to start the meds this morning. I just would prefer that I was monitoring him for the first time. So far he is acting very drugged and drinking and peeing ALOT. In fact twice so far he has not been able to make it out. He has eaten a little but mostly just the canned new food which is just a small percentage of what he is suppose to get. He is very unsteady on his feet. Actually at this point, he can barely walk without falling all over. All this is very sad to see such a vital, active dog at this point. And of course, he wants to be with me constantly - if I go to another room, so does he. With the kids and all the dogs here it is very hard to stay in one spot very long. Poor, poor Snoopy!
