Filly biting cattle.. :(
Hi everybody, so my filly has seen and worked cattle about 3 times now. She is bred for working cowhorse, so she gets very excited and curious when she sees cattle.. Well we did a cow clinic last weekend and she really got into it and tried to bite the cattle, she would pin her ears and try to bite them! I was told by the guy who led the clinic I can't let her do that as that will cause deductions if we were to compete down the road.. He wasn't really specific on how to stop her from biting the cow though... She is 3 years old paint, very smart, learns like a sponge.. The problem is she is very dominant to anything that moves (she respects me and other humans ofcourse) I mean she dominates other horses, cattle, goats, dogs.. and wants to follow any animal that happens to get into her paddock. She is young still.. what would be the correct way to let her know it's NOT OK to bite the cattle.. do I spin her around and take her away from the cow??? I just don't want her to loose her interest in cattle, she really seems to enjoy it and me too!
