MuscleHead was an average dog ... until he hit 4. Up till that time, he fought half-heartedly, scratched, but really didn't do much. After 4 or so, he became a gut dog who killed a couple for Leon when he got older.

Jueteng was a pretty good bitch, talent-wise, who (among other) spotted Conan's Deeday weight and totally overpowered her, forcing a pickup. However, I was told Jueteng quit later at around :40 or so.
