From what I've heard hunting fools and very very gritty. I heard since there so gritty they don't live long. Got a buddy out in Louisiana that just bought one pay $3000 for him. To me little much for a dog that won't last long.
There are plenty guys i know that have parker curs that are 6+ yrs old and still hunting there tail off, matter of fact i know a guy with one thats 12+ still going. It all depends on the individual dog just like anything else some are super gritty some are gritty and some are loose. The thing with the Parkers is you got a real good chance of getting a dog with a lot of get out and a lot of bottom.
