does she start barking right at the beginning of the run or half way in to it? coz if its half way in to it its frustrated that she cant catch it
at what age did you start her?it could be cause she was too young for big rabbits ,go back to basic s let her have a few easy catches on bunnie s for now then try her next season that s what i would do.a mate had a whippet that did this but it was nt frustation it copied the beddyx whipas she used to yap,so he did nt run them together again ,after a while she stopped hope this helps BB
thanks mate il try dat
