Hi. It's been awhile since I posted here, but I read a lot of the forums. Lots of great info. :o)

I'm having what I consider a big, heartbreaking problem. Sorry this post is soooo long.

I have two boxers: an almost 2-year-old neutered male fawn named Rupert who was given to us when he was about 10 weeks old, and Izzy, an almost 1-year-old white spayed female whom we adopted when she was 4 months old.


We've lately seen some aggressiveness in Rupert that we don't like. We have an appointment with a behaviorist recommended by a vet who knows a lot about boxers, but I thought some of you might have some boxer-specific insight.

Rupert has always been very laid-back as far as boxers go. He's a total lover. He has always been extremely dog friendly and LOVED the dog park more than anything. He lived to play with other dogs, and would find any other boxers at the park and play with them happily until we had to leave. He's always been great with kids and all people. His love of dogs and boxers in particular inspired us to get him a companion. He’s always been a very good boy.

Izzy had been living with some folks who kept her chained up in the backyard all day before we got her in August. She started escaping, chewing through chains, leashes and cable leads so she could dig her way out of the yard. She is an amazingly affectionate, very bouncy and super mischievous, but she's smart and is learning. She has never tried to escape our yard. :o) She’s pretty dominant, and tries to boss Rupert around quite a bit. He gets fed up now and then, but in general, he takes it in stride. When he gets annoyed, he body blocks her so she’ll back off. It’s like he’s trying to train her. Generally, they get along very well and play alot.


Rupert has gotten very intolerant of (aggressive toward) other dogs. When we take him to the dog park, he plays fine for awhile, but if any dog mounts him or plays too rough or sniffs him too much, he snarls, growls and snorts like a crazed beast and immediately gets the other dog on its back, holding it there until we pull him off. (When he's in this state, he doesn't respond to voice commands.)

He's now very bossy with other puppies. He doesn't do the growling and snarling, but he gets pretty vocal and has on occasion made puppies submit to him.

He hasn't ever bitten a dog or seemed like he was about to, but I worry about how other dogs might react to him, so we quit the dog park. This makes me so sad, because he used to love it.

On one occasion, the neighbor’s male dog (a cute, small, fluffy bedroom slipper thing) came over to our yard in a friendly manner while we were preparing for our walk. Rupert was on leash, but he pulled, snarled and growled like he was going to KILL the other dog. A few weeks ago, we were on a trail walk, and a friendly off-leash (why? why? why?) dog approached Rupert and Izzy. Rupert got tense but seemed OK. Izzy did her usual boxer puppy thing, trying to jump up and box the other dog. When Rupert saw this, he immediately growled, snarled and lunged toward the other dog, pulling me with him. He got the other dog on its back and held it there until I could yank him off.


This is not the Rupert we have known for so long. He has always been very tolerant of other dogs and in the past has gone out of his way to avoid any and all dog scuffles he sees at the park. I've always been so proud of how much he loves to play with other dogs. :o(

One other thing: We moved from San Diego to Portland, OR, last year. We don't go to the dog park or dog beach as often as we used to due to some schedule changes, but we were managing to take him there a few times a week until he became the beast.

Someone told me it’s because he feels the need to assert himself with the new dog in the house, but someone else told me it’s because he’s not a puppy anymore and adult male boxers, even neutered ones, are very aggressive. Yet another person mentioned the possibility that he comes from a bad bloodline.

Our dogs are part of our family, and I can’t bear the thought of Rupert being miserable, but I’m not willing to rehome Izzy. I miss going to the dog park with Rupert and taking him everywhere. I’m so sad that Rupert can’t enjoy that activity anymore. :o(



Any advice or insight will be very much appreciated.
If you made it this far, thank you so, so much for reading.

I am curious if Rupert displays the same behaviors when out on his own--without Izzy in the picture. I also wonder if the behaviors are directed at a certain type of dog, i.e. unneutered males, young exhuberant dogs that are paying him unwanted attention. Would he react the same to an older, calm, unassuming female? You've done a very nice job describing his interactions with other dogs. What is his body language and posture in the minutes before the actual interaction--when he first sees the other dog?

Hi,

Thank you for replying. :o) We tried the dog park last week without Izzy, and he got aggressive with a very happy, friendly Lab mix. We corrected him, took him to an empty part of the park for some obedience work, then left. As we were leaving, and unneutered male Golden Retriever pup (about 7 months) tried to mount him. Rupert got very tense, his back hairs standing on end, but we had him on leash at this point so we were able to control him. So while I won't say that Izzy hasn't been the initial trigger, she no longer needs to be present for him to be cranky. Oh, it happens when he's alone with me, alone with my spouse or when we're all together.

His body language before most of the altercations is pretty relaxed. When the other dog approaches, he gets stiff, lifting his chin up and pulling his head back to "keep an eye" on the other dog. Interestingly, when we're out for our regular walks, he never, ever reacts to other dogs he sees along the way, or dogs that might bark through their fences, etc. He might turn to look at them, but he's perfectly happy to just walk on by.

I haven't seen him around an older, calmer female. We were actually looking for an older female to adopt, but when we heard about Izzy's less than great situation, we wanted to help her. She is very high-energy. We're going tomorrow to get each of them doggie backpacks. Maybe a job to do will help them.

I have similiar issues with my girl. Ms. Ali is 5 next month and since she turned two she has issues with a lot of new dogs even more so if she's with another dog which I'm assuming she thinks she has to protect. Up to 2 she was happy go lucky with every dog big, small but that all changed once she matured. She was attacked at the dog park when she was about 18 months and another couple of times a lab became aggressive with her. So I don't really know if that made her more protective of herself or if it was just that she matured. She has lots of doggie friends and when she met some of them for the first time she had no dominant issues at all. But for the most part she will lunge at most dogs that come near her and lke I said more over if she's with another dog. Once she's friends there's no problem - the occasional I'm the boss if there's 2 or more playing. So she's dominant but at the same time I've seen her lie down and be submissive when another dog becomes dominant with her. She's never hurt another dog and has not even scratched one but I'm very weary of her around small dogs because of her size. Our own little poodle is the boss here and she complies with him. I do believe it's dominance and in her case I think it's about fear too. So needless to say I don't let her run off lead anywhere she can come in contact with strange dogs. She has her buddies and that's who she plays with and usually that's at the ball field. Apart from that she's a baby and is the sweetest, gentlest girl you could want and we love her to death. I think seeing a behaviourist at this age is a really good thing. Pls. let us know how you make out. Good luck.

Glad you posted this - but sorry you are having troubles. We are experiencing similar issues with Duke - he will be 2 in May. He has always loved meeting new dogs on our daily walks. Now he acts like he wants to meet them (happy and tail a waggin') and 2 seconds after the initial greeting he is now growling and trying to get the other poor dog down on the ground. Would love to know what others have done to work through this issue.

Hi,

We tried the dog park last week without Izzy, and he got aggressive with a very happy, friendly Lab mix... As we were leaving, and unneutered male Golden Retriever pup (about 7 months) tried to mount him. Rupert got very tense...So while I won't say that Izzy hasn't been the initial trigger, she no longer needs to be present for him to be cranky.

I just have to say, it may be that his reactions are entirely understandable. There is nothing I dislike more than "happy, friendly" Labs. They are some of the rudest dogs I've ever met (and I've owned a Lab!). They come up in a dog's face with no regard for proper dog etiquette. The only thing I might dislike more are their owners who insist "he's just being friendly." As for the GR mounting your dog, at 7 months that pup is really an adolescent who was deserving of a correction by any dog he tried to mount. That being said, it is still entirely possible that your dog over-reacted or reacted too harshly for the circumstances--it's hard to tell without having seen it.

It is wise that you are consulting a behaviorist on this matter. It will be interesting to hear their take on things. Please post an update after the appointment.

Very interesting...

My just-turned two year old is starting to act the same way when we're in the dog park. He was ALWAYS the happy-go-lucky complete lover of the dog park... everyone called him the "Mayor" or the "welcoming committee" and now he is still happy-go-lucky... but he always seems to find one dog to pick on.

I've noticed a trend also, they're usually english bulldogs. And when there is a ball and he has it... he's started to snap at other dogs who try to get it from him. He NEVER used to do anything remotely like this before. He would either just run away from the other dog, or just let the other dog take the ball. But also... when a new dog enters the park that he doesn't know, he automatically starts to "overwhelm" them with boxes and he has NEVER been this way either. So now, I usually keep an eye on the gate and grab him and put him in a sit and do a couple tricks to get his mind off of the fresh meat entering "his" dog run.

I'll watch him, and it usually starts when other dogs are playing together and he comes along staring at his "choice" and goes over and "boxes" it. Now I know he's a boxer and well, boxers box, but there are a bunch of dogs out there who do NOT appreciate it. More than anything, I think he just gets jealous and wants his "choice" to play with him.... but then he just gets too aggressive with his boxing, raised hackles and whatnot and the other dog usually "fights" back.

Let me say, he has never drawn an ounce of blood in his life. When these fights happen, they are broken up very quickly and lately I keep a squeaker in my pocket which catches his attention much better than my voice when he's in his zone. It's just incredibly upsetting that he's turning into the jerk of the dog run.

Could this be just a phase? Or is he truly just a jerk? Is a visit from a behavioral trainer in order?
