there is no set age tom, people will tell you all diffrent ages 6month to 18 months!
you know your own dogs you will know when they are ready,
i have two on now that are just a year old .
one was well ahead of the other so she started
at alot earlier on the lamp ,just sqatters and easy runs.
the other pup went out only a couple of times then the season finished.
for me its all about knowing your dog.
and we know that from the basic training
all the best with your pups ,
