So if you show in a regular class and win that class and go on to winners dog and you win, and you show in the hunting retriever class and you DO NOT win, I think you cannot show in Best of Breed , correct?
Does losing a hunting retriever class effect the winners ring at all?

Hunting dog is a non-regular class that champions can enter, so does not impact winners. Most of the time this class is judged after winners dog. However, if your dog is WD but does not win the hunting dog class, it cannot be considered for Best of Breed as all dogs in the BOB ring should be undefeated.

Makes sense , I knew that about being undefeated for BOB , but I could not put together how it might effect WD THanks!

I meant that since Champions can enter, this class does not impact winners. As with any class, the dog must meet the requirements to be entered in the class.

Yes, but if it loses the non-regular class and therefore is ineligible for BOB, does the dog still go back in the BOB ring to compete for Best of Winners?

I believe the dog is not required to be titled (JH, SH, MH, etc.), but to have successfully completed at least one leg towards their title.

The dog DOES have to have a JH, SH, or MH, Not just one leg. If the hunting dog or bitch is Also entered in a regular class, say open and If they win their Open class and go on to win WD or WB, BUT get 2nd, 3rd or 4th or not place in Hunting retriever, they Can Not go back in for BOB or BOW, as they were defeated. Also in turn if you enter Hunting Bitch or Dog and go Winner's you Must compete in the Hunting class in order to be eligible for BOW and BOB. Happened at a local specialty a couple years back and the show secretary told Winner's bitch that she had to go back in for Hunting retriever bitch in order to be eligible for BOW. Couple years later, a dog won hunting dog, but did not place in Open black, was Not eligible to go back in for BOB or Best Hunting overall since he had been defeated in one of his entered classes.

YES, YOU DO have to have a Hunting Title, JH, SH, MH!
I will say that I am pretty proud when my boy who has a hunting title is one of only a few in the Hunting Dog class at a 250-300 entry at a specialty!

The past few years, Hunting Dog has been one of the largest classes at our specialty. I like to enter this class because this is the real purpose of dog shows for Sporting breeds – showing the best of our working dogs. The requirements for entering the class at our club’s specialty is a JH, SH, or MH title or a JAM or better at a licensed field trial.
