dog isnt as good as she used to be???

I had a dog do that once. When i got the dog she had been hunted but the made a brood gyp for a year after two weeks of owing her i took her hunting and mad let me tell you she was a ball of fier she was striking hog the hole nine. Then one day she just quite and became a help dog i tried every thing in the world and nothing seem to bring her back. Ended up selling her to another guy as just a help dog and shes his main strike dog.The only thing that i could think of was when she was hunting her but off she more or less became my main dog and i bout the time she quite was when i got a strike dog that she could not match. Mabe some dogs just like to lead and not follow. jmo bryce
