I have a 1 yr old GSP that show no interest in birds what so ever. I finally found some pigeons so today I planted the bird and put the dog on a 20 ft lead. First off he does not want to leave my side so I walked around the bird and nothing.. So I showed him the bird he sniffed at it and that was about it. So I put him back in the pen and took the other dog out and ended up killing the bird. I then swapped dogs again and with no lead I let him smell the bird I put it on the ground and nothing so I threw it out to retrieve and he never left my side..I am at my wits end on this dog when I take them both out for a walk it takes him forever to leave my side.. What can I do about that and not being birdy at all
