I don't dislike what you said. I've said similar things. The decision to give her to a rescue is not one we would come to lightly, but it may be the best option for us and for her. The rescue works to find new families for dogs. We wouldn't give her to a shelter where she could be euthanized, and we don't view her as disposable.
The plan is to try another round of training, but it may be a last chance for us.
Keep in mind that every seizure causes some brain trauma.
We went through that with Halla when we first got her.
The vets were more concerned with the possibility/level of brain damage from the seizures than her other issues.
