That sounds scary! Tripp needs to be examined by his veterinarian today if possible. Pets can have seizures for many reasons including liver disease, idiopathic, electrolyte imbalance, infections, inner ear problems, cancer or epilepsy. He will need a physical exam and bloodwork to begin to narrow down and appropriately address the cause. Seizures are serious and are best addressed early.
You need to stop breeding Tripp as well. With the puppy having seizures and now him having seizures, you should not pass on his genetics. Have him neutered to make sure this doesn't happen. I hope this helps and please feel free to post any additional questions.
