That is ridiculous. Vitamin D does not prevent seizures. Please see a vet who knows what he's doing, before your dog has any more seizures without a correct diagnosis and treatment. Blessings - Blu
Sorry but this is just odd. Does your dog even have a seizure disorder? I have never heard of such a thing.
He was shaking like a leaf for about 3 days and I noticed he was running a temp and thought it was an infection. Vet gave me antibiotics and after a few days he was feeling like his old self.
