you can perhaps tell show potential at about 3-4 months show quality isnt before 6-9 months at best...your hoping for the best at 8 weeks, many things can change in conformation, coat and teeth between that time and 6 months!
you mention all shots yet you are sending them on their way at 8 weeks...first 8 weeks is far too young to send them off second you would have to had started shots at birth to give 3 shots (that is what a pup requires) shots are not effective until at the earliest 6 weeks so I dont understand!! Also they are spread out in 3-4 week periods...
your statements do not make sense!
