I started some training with a member here, (Undertaker) and watching his dog Fancy run just blew me away. This ANIMAL/FREAK is1yr and 8mo old and under 50lbs and can run and jump like an antalope, (while handeling great) no B.S. Fastest dog I have ever seen. Leaves skid marks from and to heel! At 6 mo's, my pup still is kind of awkward. I have seen his parents and both are fast. I guess my question is at what age do they really take off.
