Wow very cool dog! I know we Adopted a black Lab afte rmy wife saw it get hit by car on the way home from work, Had tags but no owner would call me back so after $1,500 in med bill he is healthy and sprited. I have been starting this with him and he seems to be picking it up but he is abou 4yrs old now, I will be planting some birds in my brother in-laws field and see what he does. Hopefully you can teah a older dog new tricks. Good Idea about hiding the wings BTW.
