She produced great, and yes she passed it.
Her son Thunder, and her daughter Screamer (both to Poncho) comprise the highest-percentage game dogs I've bred.
When I bred Poncho back to Screamer (off Red Sonja) that is what produced Duke, Jezebel, Athena Red, Mystery, Laguna Sunrise.
Not only was it an all game litter itself, but no dog matched off of any of these dogs ever quit either. Almost all of them won, with 1 loss (game to a Ch) and a draw in 2:50. The rest won, many in over 2 hours.
Thunder was only bred twice, and is the dam of Sassy, Razor (dam to Ch Miagi, Ch Pierce, etc.), Lu Lu (dam to Ch Mr. Serious), as well as Mileena (dam to Ch Monster), etc.
So the gameness in Red Sonja was no fluke
