A Seizure While Shopping I Got Home And My Dog Won't Walk. Is My Dog Paralyzed?? I?

I got home and my dog won't walk. Is my dog paralyzed?? I? - a seizure while shopping

I have a 5-year-old English bulldog that refuses to go. He was good this morning, which is very slow and lethargic (sleeping almost) the whole day, but was on the couch, he was jumping into the situation. We went shopping and when we return, he could not walk. Not able to convince him, he simply slide your legs. You can move, but. only very slowly and is not a burden to them, especially the right side. I have the brush on the back and hind legs, and held it hard, but it was not in the hand pain. It growls when pressed on the inside of the thigh, but do not scream. As I said earlier, you can place, I put weight on it. Later, he pulled the mascot, I'm not sure about the immense pain. If you have any idea what could that be? He has a history of seizures and Phenobarb. And if it was an attack, while away, and she fell off the couch? Please tell me it is more likely to heal ...
