My dad went pheasant hunting with some guys from work once... One of the guys had a Beagle that wasn't a very good hunting dog... He said they spent more shells calling the dog back than they did shooting at birds...
A guy came along with a German Short Haired Pointer and wasn't a hunter, but asked if he could walk with them to exercise his dog... So they put the Beagle in the car and walked with the Pointer and his owner...
One guy shot a pheasant over a lake and the dog jumped right in, swam to it and brought it to his master's feet and dropped it, then walked 6 feet away and shook off and then sat and waited for the next command to start hunting again... This was in 40° weather, one of the guys said he got the chills just watching the dog do that...
That dog was so good, they bagged their limit within a half hour...
