Oh Jennifer, that SUCKS!! Especially when the dog is good with kids. To be honest, I wouldn't have them over--for exactly that reason, the dog lives here, your sisters kids don't, either she works with you to get her kids used to the dog, or she'll have to have you over there.
How is your dog doing anyway?? did you get anything figured out with the seizures?? (that was you right??)
