I need help.
I have been away from the forum as I have been busy but I am now forced to take the time and sincerely ask for your help.
I got Allie a few weeks ago. She was going great with my goats...up until now.
She isn't as calm as I was told and is actually quite wild at times.
She did chase the chicks a few times, which I tried getting to to quite that but she still does it if she had the chance.
Not sure what went wrong as she was raised with all animals...even chickens.
As of 2-3 days ago she started chasing my goats

I CAN NOT have that.
The reason was while I was gone working my siblings didnt close the goat door and they got out. So to herd them back in they trained MY pup to herd/chase them in. I saw it as I was pulling in. I was so mad.
Keep telling them she isn't a herd dog. She has also been trained to herd the turkeys in

So now I just spent $350 on a doeling and my pup is chasing her mostly.
Now I can't keep them together anymore. Allie sleeps in the milk parlor now.
During the day I have been tying Allie out...as she doesn't like being cooped up inside. When I am with her I let her loose and have been working with her when I can trying to leash train her.
Ideally she would be in a fence with the goats by day and inside with them at night. However it has been too hot to where I prefer to leave the goats in and run a fan. Also my fence is down and I am installing a new one and waiting for a 20 mile fence charger to come in the mail.
I guess I didnt do enough research. Hopfully I didnt ruin a good pup
Also tonight she was "playing" rough with the goats as they were eating their hay. They always counter-attack, which seemed to please Allie.
She would jump at them, threatening, she would even chew on their ears (just put them in her mouth...no damage done).
I have never seen her act like this. She has always been good tempered.
Of course through all this she was super hyper...maybe was trying to play but I can't have her play like this.
Just this morning she would still give her favorite doe kisses like she usually does every milking time. She has always liked the one doe. She would give her "kisses", put her front paws on her (and surprisingly the goat didnt mind), and sometimes even sleep with her. Many "cute" moments with that pair...then tonight she is acting up.
Although she was gentlest with her favorite doe (Juna), she still was rough enough that Juna fought back.
And I thought I was making progress with this girl. Taught her to sit, lay down, and sometimes roll over. Leash training is coming. She leads, with some persuasion at times. Sometimes she takes the leash in her mouth...which I don't allow or sometimes tries to get ahead(which I also don't allow).I pet her while she eats and never any aggression while eating. She is always happy to see me. A nice puppy.
Now can I teach her to stop chasing the goats and playing rough with them?
How do I correct the damage done?
Obviously I need to take more time to research and see what I am doing wrong.
I got this pup for a days work on the agreement that she would have a forever home...just she won't have a forever home with my herd if she doesn't come out of this. HELP!!!
