My Aussie Is Suddenly Dog Aggressive...

Rumor

Rumor

I have owned Aussies my whole life. I have my 5th one now, a 2 1/2 year old female. She is the sweetest thing ever or at least she was. Suddenly, she is attacking my other dog for no apparent reason! I have 2 other dogs (a 3 year old Border Collie/Aussie, and an 18 month old German Shepherd) and 1 foster (a 1 year old Boxer mix). I am VERY careful about 'integrating' fosters into my 'pack' (I have been fostering for years-no problems.) They were all living peacefully for the last week and then it happened... my Aussie attacked my German Shepherd out of the blue and my Border Collie joined in (a pack thing?)

I thought everything was ok (thinking back hind-sight, thought it was over 'fast food' YUMMY)so... no more food around the dogs. Two days later, everyone is out playing together ( I am with them) and all of a sudden... she attacked my Shepherd AGAIN! And then they all jumped on her!! I was alone scared to death but managed to get them off of her with minimal damage...

WHAT IS HAPPENING TO MY SWEET DOG???? PLEASE HELP ME HELP MY DOG!!! I don't want to get rid of her but I cannot have this behaviour. They all get LOTS of exercise, go to the dog park, well socialized...

My Aussie Is Suddenly Dog Aggressive...
by: Anonymous

That's interesting as my 20 month neutered Aussie male has recently started being snappy - mostly with German Shepherd males too. He doesn't look for trouble but if they get in his face he let's them know in no uncertain terms that he wants them to back off.

Re:Your comment

Thanks for that interesting fact. My last aussie male was dog aggressive but only towards Rotties and Chows (I adopted him at 8 months) I thought maybe it was an issue from his past..My current aussie I have had from 8 weeks, no 'bad' past (attacks,etc) My shepherd is VERY passive(and spayed) so she shouldn't be threat right?
She has gotten better the last few weeks but not without LOTS of obedience(back to basics) and LOTS MORE excersise(like til she's exausted!)
I still don't trust her,and keep her in my sights,on a leash in her kennel at ALL times. She isn't allowed any freedom without my say so..
and I don't allow her with the other dogs unless there is someone else here with me.
I wish you the best with your dog..Good luck.

dog aggression in aussies
by: alicia

HI Kim, I have a 16 month old female also blue merle. I have been taking her for obedience training and agility since 7months old. I have also taken her to dog parks, she has displayed aggression but also saw improvement depending on certain dogs that were there. Anyway, she also acts aggressive esp. when on leash. This past fall my husband and I would take all our dogs for a 1 hour hike and meet dogs along the way. I saw improvement when we stopped she would greet in a nice way without lunging or growling. Other than this she is a fantastic dog and very smart and funny! Hoping I can find a way to stop this esp. for agility. There is a you tube teaching on what they call counter conditioning. It looks like it works too!

Kujo is ball mad, and loves nothing better than flyball and is very focused when he thinks there is a game on hand.The way I am handling this at the moment is that when I see another dog approaching that might be an issue I show my boy the ball and he completely ignores the other dog. He only goes back on the lead if he looks like getting involved and that has happened for a while now.

Re: Suggestions
by: kym

Thank you all very much for your suggestions and your own stories. I am willing to try ANYTHING for her to be a well rounded dog. If nothing else it's nice to know there are people out there willing to help and not criticize!! Thank you to all! And we will keep working!

unusual aggression
by: Marg

Hi! My own Aussie, always friendly with every dog she met (she is 5 years old) has recently started attacking small dogs and been much quicker to initiate a "rumble" with other dogs. I called her trainer who suggested I get her thyroid checked out. Apparently if a dog is hypothyroid it can cause sudden aggression. As I already treat my girl for low thyroid, this is probably not the reason for her behavior, but you may want to look into this or at least read the literature on it.
Good luck!

My assie is dog aggressive.
by: Del

Hi Kim,My Aussie is 2yrs old now and she has been aggressive since she was a pup around 4 to 5 mths old.She was realy bad then,she would would see another dog from a fare distance and she would pull me trying to get to the dog.
As she got older she got much better,I can just about walk passed a dog before she attacks but it is not all the time.I do obediance with her and she is good if she is focused on me,but if another dog gets too exicted that wiil send her off.I would be happy to be able to have her relaxed next to another dog.I think it is a matter of letting them know your in control,which is something I'am still learning to do.So good luck to you and staying calm I found works well..

Daughters visiting aussie attacked my small dogs
by: Anonymous

My daughter left her aussie with us for about 2 weeks. I have 4 dogs...one female old golden,an old female chiwawa,an 8 year old small male mix(not sure what)and female chiwawa mix. All my dogs are 8 plus years and set in their ways. My daughter's dog (named Dunngy) is only 71/2 months old. Her dog out of the blue attached my old female chiwawa by the hip and tossed her. growling and ready to hurt her more but We intervened. We disciplined Dunngy and he seemed depressed and remorseful but later the same evening he again attacked my little male dog by the throat and wouldn't let go...all the while we're yelling and pulling him off. Three days later in the backyard after a nice long walk and swim he again attacked my little male dog.This time there's blood and no reason for this behavior. We immediately had Dunngy nurtured and made arrangements for him to be picked up with my daughter. My Question...do I trust that this is now an ingrained behavior and should I not have him visit again or do I hide my dogs away from him if he's ever over again?

Australian vs. German & then Aussie vs. World!
by: Anonymous

So I accidentally stumbled across this page & found your story very similar...I adopted an Australian Shepherd about 1.5 years ago now, who was a foster at the dog daycare I work at. I happen to have a German Shepherd who I rescued as a pup pup. I fostered my Aussie for about 3 weeks to see if she'd fit in the pack, and all was well. My German was 3 at the time & the Aussie about 2 we think. Yes they have had their sibling fights, 4 to be exact, the were nasty, I got hurt more then them....but they both saw red...usually a jealousy thing, not putting blame on one or the other, it always happened so fast...I know why my G. Shep "sees red" when someone goes after her, because she was attacked a few times as a young dog, she's anxious & fearful now...but my Aussie brings it, yes it's true, the alpha dog! She plays great with other dogs, the rougher the better, BUT...if in anyway she feels dominated she'll try to bite and growl and pin the other dog down. With the exception of fighting her sister/best friend she has never actually done any harm...it looks and sounds scary, but that's not her "red" cuz I can call her off easy. Long story short... The breed does have a stubborn spell...breed for taking control. But most of your comments weren't a "breed" issue nor a "breed on breed" issue, they were all about who was really in control! The "pack leader" It sounds like in all our houses our Aussie's are the pack leader, whether we want to admit it or not!

Newly Aggressive Aussie
by: Anonymous

Hi - I'm not sure how old this post is, but recently my 10 1/2 Aussie is becoming aggressive towards our other dog (a 5 yr old American Eskimo). They've been living together for 2 yrs after I took her in from my parents, but have known each other since my Eskie was 6 months. They've always gotten along great, to the point that the dog trainer we had come to our house a couple of months after we had taken in the Aussie to train them together (for walking and barking purposes) said she couldn't believe how dependent they were on each other and how they had formed such a strong pack together.

Over the last couple of years we have learned a few things, like she would become toy aggressive, but we bought each dog their own toys (different in styles) and trained them to not touch each others toys, which completely stopped that negative behavior. We also have two completely different dog bowls in different spots in the kitchen for feeding and make each dog sit in front of their feeding spots before putting their bowls down and until today there really hasn't been a big issue. However, today my Aussie started to growl next to my other dog as he was eating his food and before I could get there she was attacking him! I've noticed in the last couple of weeks that she's been hovering around his dish, but didn't think anything of it until now, but I guess hindsight is 20/20!

I guess my question is after this long post, has anyone else seen this start to happen in their Aussie? And/or does anyone have any recommendations? I have to leave for work in a couple of hours and am thinking of separating them for the first time since they've been together because I feel a little nervous leaving them alone.

Aussie Aggression

My 2 1/2 year old aussie is loveable as he'll but will snap without reason or over react and attack our 9 year-old mini schnuazer. We also had an issue with snapping at a young child when she ran toward the puppy. Any assistance would be great! My husband did not see him and stepped on him got bit but not hard to draw blood then went after the schnuazer just for being there.

Aggressive Aussie
by: Candace

Just read others posts on aggressive aussie's.
We have a 1yr old Aussie and a 7yr old German Shep. The two boys got along grand, until recently, this week,our Aussie, Frodo, picked a fight with our German Shep. Samson. It was very scary. had all I could do to pull them off each other. Sam has puncture wounds on his leg. Later in the week, Frodo did again with my neighbor's Aussie, who is Frodo's litter brother. It was all out war between the two. I tried to break it up. I got bit in the process. Both dogs are ok. but it was traumatizing for me and my daughter. I've enrolled Frodo in Obedience right away to curb this behavior and to learn how to deal with this behavior.
