Lola is older. She is 9. Lucy is 4, and has been aggressive towards on and off for several months.
They have both been spayed. Lucy is a mixed breed/mutt. Lola is a dingo/sheperd mix. We have one other dog, Buddy. He is a chow/lab mix. He is 11.
There is no rhyme or reason for the aggression. They used to sleep and play together. Then just just shortly after I came home from the hospital from surgery, Lucy would attack Lola if she on my bed. Then just off and on from there.
There has been official obedience training.

Correction...there has been no official obedience training
Dog Trainer: Jane Lefler, Animal Behaviorist replied 2 years ago

Thanks for the additional information. It is helpful. I suspect that Lucy has recently decided that she is the boss and as the boos, it is her job to reprimand Lola especially since Lola is older and likely to be having some health issues making Lucy feel she is the best choice. It may have been that Lola was the established boss before. However, when you were in the hospital, there may not have been strong leadership from Lola and you were not there to be the ultimate boss.

When there is a change in leadership in a dog pack, the new leader often feels like any slight or disrespect needs to be reprimanded. As the new alpha, she would feel like she should be fed first, get attention first and get to be on the bed with you first . Lola would only be allowed attention, treats and to sleep with you when Lucy indicated it was ok with her. You can help a change in leadership by recognizing that the younger female is now the boss. Treat her that way. Feed her first, give her attention first even if Lola happens to get to you first. If you give Lola attention first, Lucy will likely reprimand Lola with a nip or even a fight. This sill also help Lola see that you recognize Lucy as the leader. If you continue to treat Lola as the boss, Lola will feel like she is and Lucy will feel the need to reprimand her even more.

Start obedience training with them. It doesn't have to be a formal class, but training needs to be formal in that it should be the same times every day and structured.

The following site is helpful in helping owners train their dog. Be sure and click on the link to the page on obedience at the bottom. and links on subsequent pages leading to detailed instructions.

http://www.schutzhund-training.com/training_theory.html

Training works best if you train at least 30 minutes a day (two 15 minute sessions). I would start making your dog work via the Nothing in life is free program (NILF). It is outlined below.

http://www.pets.ca/articles/article-dog_nilf.htm

http://www.humanesociety.org/animals/dogs/tips/training_nothing_in_life_is_free.html

Additional training can also help. Both dogs should be leashed and if one dog even looks at the other dog, a correction should be done. Any sign of aggression including a prolonged look, hair raised on the shoulders, a growl or even a stiff legged walk, should be corrected. A correction is a quick tug of the leash and a firm low toned "NO". Once you have done this couple of times, you should notice the dogs ignoring each other. When that happens, you will want to reward them for the desired behavior. Again, use tasty treats like the hot dog slices. This teaches the dogs that you WILL not tolerate fighting in YOUR pack.

Your hospital stay likely triggered the change. I want you to also study body language. It will allow you to understand how the wrong tail position might cause a fight to occur. Read about body language here:

What Customers are Saying:

I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there.
