Daughter's dog is 20mos exercises, walks, and runs regularly, but I can still beat him....read these dogs can run up to 30mph but at what age is that? The last time I ran a sub 5 second 40m was 5 years ago (last time timed but TBH I know I ain't getting younger), so I know I'm not getting faster. Anyone know when they reach their peak? I'm guessing another 2-6mos.....
