Yes this pup has Cosmo in his pedigree and very difficult to work with. Some time ago Randy posted what to do with a dog that was noisy. So I have been following his words of wisdom. No this is not a sight blind? Every time we are out if he is quiet putting the flat collar on, going in the truck, coming out of the truck and walking with me and at the line, he gets 3 different blinds and some stand alone marks. This is a slow process with Cosmo but he has lots of years left. His real name is Yorktons Ironwood Chief and I nicknamed him Cosmo! after I read all about Cosmo.
