Was the Wheaten used in the mating pure? I have worked this cross before and they have a good nose, not needed when your lamping anyway as they tore down the beam, great lamping dogs!!!! If anything they can be to headstrong.
I believe so.
I got the dog at over 12 months old and i think he had been encouraged to hunt with his nose so when i tried him on the lamp he ran the rabbit then went nose down like a bloodhound when he lost it.
Its a habit i have not been able to stop so i dont use him for lamping.
