If you catch them tied again.....do not try to seperate them! You can seriously injure your girl.
You will have to wait it out.
I know of someone who's husband was home alone with her dogs (not sure of the breed) and he didn't know any better and pulled them apart, killing the female as her insides were pulled out
This was YEARS ago but still
So just wait it out if they tie again, but you may need to keep them seperated until this passes.
