Pups in good shape atb. Just a thought if u have anymore problems looking down beam play a bit of throw at night with the lamp or even get a dummy stick a bit of silver foil on it as a eye to reflect the beam.
I like to get a young dog out doing a bit of ferreting at around 6 months before going on the lamp. But before that I also like to get pup out as soon as possible with the air rifle to further retrieve training.
