One of Our Australian Shepherd Puppies Is Attacking Her Sister

by Janet
(Fresno, Tx, USA)


We have four Aussies. The mom, dad, and two of their puppies, both female. The pups will be three years old in a couple of months. A while back, one of the pups began attacking the other pup. She gets along great with the mom, dad, and other dogs she's introduced to. But her sister is the one she likes to attack.

We have had to keep them away from each other by kennelling one, (the aggressor) so the other can play with the other dogs. The other sister is very sweet and gets along with everyone, too.

We don't understand what is causing the other sister to attack her. Believe me, it is not play fighting.

Does anyone have any tips on how to solve this problem? Any advice will be appreciated. Thank you.
