Hi Melissa,
I have never had a dog who has had seizures. But I would suggest to not rush. Enjoy Presley and learn with her. Give her lots of love and when the right time comes, add a playmate for her.

Labs are great with babies and even if she is a couple years, the difference is not that much. They will still be playmates and bond.

My advice is to wait. Share this time with Presley and learn to train her. The next puppy will be so much easier if you take time with this one!
