I have a cousin who is very close to me. She has a horse and we ride together and hang out a lot. She also has a Border Collie.
This dog, she got her as a six month old. The dog had been badly abused and is super active and so inbred that her herding instinct is crazy high. However, instead of channeling that into work, my cousin just lets her do whatever.
The dog is not an aggressive dog, and I really like her, but I'm about to start getting after her with my lunge whip. My cousin doesn't see anything wrong with how the dog acts. She is always making excuses for her. Her horse constantly has marks on his nose and back legs from where the dog has snapped at him trying to herd him.
The dog also tries to herd my great grandmother's chickens and terrifies them. My great grandmother has told her time and time again to either get her under control or she's going to start shooting the dog with a BB gun. My cousin yells at the dog to stop, and then says that it's in her nature and she can't break her of it.
When it comes to the horses, though, is where I draw the line. This dog snaps at my horses back legs if they so much as move when we're working with them (with them tied or something and are being groomed). It makes my horses jump and in my boy Jax's case, it scares him, and he already doesn't like dogs that much and has tried to stomp this dog several times before.
I told my cousin yesterday when I got fed up with it that if she doesn't get her dog to stop, my horses were going to kill her one day because I won't stop them from kicking the dog if she bites them. My cousin said that the dog couldn't help how she acts. I told her that she could be trained to not act like that, and my cousin said that she couldn't be.
I said that if she dosn't keep her dog under control around my horses, then next time I was going to get my lunge whip and get after the dog (and I will hit the dog with it, not just scare her). My cousin said she'd get after her herself, but just yelled at the dog. I told her again that if her dog bites my horses one more time, I'm going to whip her with my lunge whip because she has to learn that she can't do that.
My cousin just said that she'd lock the dog at her home when she comes up now, or tie her... but I know that she won't. She only pens the dog when she's in heat.
Am I going beyond my boundaries here if I go through with what I told her and do get after her dog when she won't? I am not going to sit back and let this dog keep biting at my horses, and it's not just because she bites them. I also do not want this dog to get hurt or killed by my horses.
