The rancher where I train has a lab that is about 7 yo. I did the basics on him a long time ago. Now for the privilege letting me train on his ranch, I run his dog when I am there. Sam always had good eyes. But a few months back he had two seizure separated by a month. Vet was consulted. After the seizures, he acted like he couldn't see beyond about 30-40 yards. So I kept everything short and simple for him to let him have some fun. Late last week I inadvertently short a long mark for him. He did well. So all this last week I have been running him on the same marks as Rowdy. Sam has been doing them and doing them well. All singles so far. A mixture of bumper boys, ducks from wingers and wing clipped pigeons from a box launcher.
I thought this was remarkable.
