Aggression and initiating fights. How to deal with it?


  • Btw.. Tillo was also scared of the Shar pei that wounded him during agility class. He didn't want to go on the training field when that dog was there.. Because he had to, he would keep looking around where that 'nasty' dog was from behind my legs. If that dog was too close, he would growl. I don't feel ok with him doing that, although I can understand why he does it and I was kind of scared myself too :rolleyes:

    I made sure that from the minute we stepped on the field, Tillo focussed on me. Happy voice + some treats worked ok. I parked him behind a closed fence if I couldn't pay attention, so he could not fixate on the Shar pei. Now if he sees that dog he will look, maybe growl and he will look up to me if I say his name. It makes things a lot easier, especially during agility when they work off leash, although I know he still doesn't like that dog and I will have to keep paying some extra attention because of this.


  • Sounds like your getting your dog settled again. Good job!


  • i would highly recommend finding a qualified behaviourist in you area to work with you.

  • Today things went very well. I had with me some nice fresh chicken, and called him to me continually throughout the time in the park. And awarding him.

    A HUGE German Shepard came to the park, and Gizmo was instantly nervous. And started growling etc. Both of them stood staring each other down.

    I didn't yell "No!", but used my "Ah-Aah" voice in a strict manner. Gizmo reacted to me, and slowly backed away, and eventually came over. He was still nervous, and was watching the Shepard. So I made him work for his treats, going trough them with sit, shake etc.
    And before I knew it, he was fully focused and paying attention to me. The Shepard was walking around us the whole time. When we stopped, he didn't react to the Shepard as strongly.
    There was a short little growl, but they both moved on.

    Gave me hope. 🙂


  • I wouldn't take Gizmo at this point to the dog park as it will put him in danger. I had a r/w Basenji that did not like bigger dogs no matter what color or breed and would get right in their face. A fenced in dog park was out for him.


  • In my opinion you are taking a chance on taking Gizmo to the dog park where I assume he is off leash? Deal with the behaviour first as suggested in the other posts and only put him in that position when he is totally reliable again. Be patient! I'd hate for Gizmo to get hurt nor any other dog.


  • I would highly recommend NOT taking him to the dog park, and definately NOT using treats while there. Food is the #1 aggressor in dog fights, so you are setting you and gizmo up for failure.
    Do you know anyone with large dogs you can use to desensitize him too?
    Please consult a behaviourist, you are risking your dog's health and mental well being.

  • First Basenji's

    As I was reading this, I was also concerned about the high value treats that are being brought to the park. Even if Gizmo is good, other dogs may not be. For example, my own Shiba has, in the past, initiated fights over human lunches that were being eaten at the dog park (in particular, at one of our smaller parks with picnic tables all over the place). He sat down nice and pretty and appeared, on all accounts, to be mooching "politely." Then the lunch eater's dog came up – as dogs are wont to do when delicious food is in the area! -- and Bowdu snapped and lunged and a fight broke out.

    We don't go to that park very much anymore, and never when food (for humans or dogs) is around.

    In my opinion, small, discreet snacks are best at off-leash dog parks, if any.


  • I don't know about dog parks anywhere else, but human food and drink, and dog treats, are not supposed to be brought to any of the dog parks in Florida. It's asking for trouble to have any kind of food around with a bunch of dogs off leash. Picnic tables are for dog water and for people to sit at and converse while their dogs are doing their thing. The few times we have seen people bring food in, someone will let them know real quick that isn't a smart thing to do. If you are training your dog with food, it's better to do it someplace else, with dogs your dog already knows around, if possible.


  • When he was about 2 and intact, Topper was attacked by a big boxer. For quite a few years he went ballistic at the sight of any boxer, female, male, didn't matter. At the dog parks I would watch the gate and if a boxer was entering, I made Topper get up on the table and stay there. Eventually I got him neutered (he was 5) and didn't expect a dramatic change, but hoped for some mellowing out. He would still growl and act up but would not fixate for so long. He eventually found a boxer he liked and now he is fine unless we encounter the "BBB" (Big boxer with balls), but he will say a little grumble and then 'leave it'.
    Gizmo can get past it with a lot of help and distraction training from you. If he won't behave, leave the park. They figure out pretty fast that "X" behavior = leaving the fun immediately. I know it's hard to give up dog park, especially if you just go there, but leaving the scene is a must if Gizmo won't come to you.

    As for treats, in general it's a bad idea. If my guys were there, Nicky would have been glued to you till you gave her all your food! Even low-value treats can provoke fights. It depends on your park and the rules, of course, just something to think about. A friend used to keep special food in the car, so the dog (rescue) learned pretty quickly that following Dad to the gate to leave was a very good thing.

    I wish you luck, been there, done that! Took surgery and a lot of behavior modification but I wound up with a nice dog who had more fun than angst at the dog parks.


  • Neutering is not an option for me, at least not yet. Here in Norway people usually don't neuter. Neutered dogs get humped by everything (females and males) when they enter the park, and the dog gets VERY stressed. I don't want to put him through that.

    The treats is not a problem. I have never encountered a dog that bugged me for them, and like you (MacPack) mentioned, I too get Gizmo to jump up on the table in the park to distract and give treats.
    I keep the treats in an airtight container, which might be why the dogs are not reacting to them. Actually, it's Gizmo that bugs others for treats..lol

    I give Gizmo one chance to listen to me. If he still stands his ground we will always leave the park.


  • Another thing to consider is that Gizmo is nearing full physical AND mental maturity. Even without the negative experience of being attacked, a mature dog typically begins to "assert" himself more frequently with other dogs in social situations.

    My Jibini was 100% playful at the dog park from puppyhood until just shy of 2 yrs old….we visited the park 3-4 times a week and until he hit 2 yrs he never engaged in assertive behavior or fighting even when another dog tried to start a fight.

    Gradually after age 2 he became more & more assertive, several times I had no choice but to take him home. After a while we became very selective about WHEN we went to the park and WHO we went with. I was fortunate to live in Tampa at the time, where Jibini could enjoy playing with a group of familiar Basenjis who met every Sunday at a particular park. The Basenjis always stuck together in an almost exclusive group, ignoring most of the other dogs & staying in one area of the park away from the main crowd. If we attempted to go to the park without the Basenjis present, Jibini would inevitably start a fight with a bigger dog- without fail.

    It was during this time that a couple of knowledgeable folks pointed out the fact that Jibini had reached maturity, and that could very well account for his newly developed "attitude". Since then I've had a lot more dog-related experience & have seen "maturity" trigger assertive behavior between 1-3 years of age in a lot of other dogs.

    Just a thought. Keep working with him if you're seeing an improvement, of course...you probably CAN make an improvement with his obedience & possibly modify his fear reaction. Just keep in mind that this behavior probably won't entirely DISAPPEAR, and may not be isolated to just German Shepherds & similar dogs. You may have to be vigilant with him forever, he may react when you're not expecting it, you may find yourself leaving the dog park more often to avoid trouble, etc.

    My male is 10 years old and I still can't always predict which dogs will trigger aggression & which dogs he'll want to play with. Rarely he'll have such a severely aggressive reaction to another dog that nothing I do can re-direct or distract him, and the only option is to remove Jibini from the situation altogether.


  • My advice is to leave the park the moment you see a dog you believe may trigger him. And make sure you see it first!

    To change your dog's reaction, you need to begin a desensitization and counter-conditioning program. Which means that you cannot expose him to his "scary thing" to the intensity such that he begins to growl. Once he's tipped into an emotional behavior, you've missed the boat on your opportunity to change his internal reaction.

    If he's growling at say, 20 feet, you can probably start to notice other warning signals before hand, such as a freeze or hard eye. Even that's too late. You have to get to him before he starts to tip - while he's still comfortable. Which means working in a controlled environment. That is with dogs on leashes.

    A good trainer can create a training program for you and work with you on this, but repeatedly exposing him to large, dark dogs and waiting until he's already growling to get outta dodge is reinforcing his fear. And the recent scuffle really reinforced it. I'd say you really need to up your situational awareness or start skipping the dog park. Every time he has an unpleasant experience with a large, dark dog just tells him he was right to be uncomfortable, even if the other dog does nothing but appear.
