Sudden Aggression Toward Other Dogs

Behavioral Issues
  • My basenji/shiba inu mix has started all of a sudden showing aggression toward other dogs.

    Last summer I took her to the dog park regularly and she was very good with other dogs and wanting to play aside from the occasional nips. This summer when I started taking her back to the dog park she has started fights with any dog that shows interest in her.

    The only change in her environment has been my sister moved in with her dog (rat terrier) and they get along wonderfully. But whenever I take them both for a walk, the rat terrier barks (non-aggressively) to any person or dog he sees and my dog growls, snaps and goes for the other dog?s neck. My dog shows no signs of aggression toward people at all, only other dogs.

    Should I continue taking her to the dog park to re-socialize her? Perhaps without my sister?s dog? This new sudden aggression to other dogs has been very concerning.

    I appreciate any insight you could provide!

  • How old is your dog?

  • She turned two in November

  • O.K. that may be part of the picture. She is growing up. The influence of the your sister's dog is likely another factor. Same sex aggression is not unusual in Basenjis. Is she aggressive with all other dogs, or just the females?

  • When was her last vet check? I would make sure that her growliness is not because she is hurting somewhere and feels that she could not defend herself (or her pack) if she needed to. Did you take her to the dog park before the rat terrier entered the picture? If so, what was she like then? If you walk both dogs together on leash, what is she like if she encounters another dog? I'm wondering if the rat terrier barking is setting her off. You COULD try taking her to the park without the rat terrier to see if it makes a difference, but you must follow her everywhere - she can't be out of your sight.

    We have stopped taking Kipawa to the dog park. I was finding the energy there not that condusive to healthy dog play. People were not watching their dogs - they were busy drinking pop and chatting. Dogs were getting out of hand and the owners were not giving them a 'time out'. I saw some scary things escalate there, so it is not an area we choose to go to any more.

  • I agree that a full vet check should be done any time there is a sudden change in behavior but it is not unusual for mature dogs to decide they do not want new dog friends. It is very common with basenjis and shibas to prefer to associate with a smaller group of known dogs then deal with the unknown dogs and varying numbers of a dog park.

  • She's always been a little snippy at most female dogs, but some in my neighborhood she's friends with. Recently at the dog park, it's hard to tell exactly what sex they are when they come up to her, but it's been every dog she's had a problem with (besides the rat terrier).
    Last summer (before my sister's dog came into the picture) at the dog park she was very playful and I never had any worry she'd start something with another dog.

    When I walk both dogs together, she's interested in the other dog, but as soon as she smells for a minute, then she immediately starts snarling and going for their throat. When I walked her alone, for the most part she'd be friendly enough. I do wonder too if the rat terrier's barking is making her feel protective.

  • I believe her wellness check was back in October. It has been recent, but I'm feeling like I need to call them again to explain this sudden behavior.

  • I would - sudden changes can be cause for concern. Please keep us posted.

  • Is she intact or spayed?

  • Good question, but she's been spayed for over a year now. Not sure if it's worth mentioning or not, but because she is part shiba, she does have a soft undercoat that she's completely shedding right now. She blows it about twice a year. I'm not sure if that can cause some irritability.

  • @DaiseyDuke:

    I do wonder too if the rat terrier's barking is making her feel protective.

    Hmmmm…. interesting thought. I know Kipawa wants nothing to do with barking dogs. He looks at them for awhile and then walks away, choosing not to play with them. That's a different action for him as he wants to play with every dog he sees.

    For the experts on here - as basenjis can't bark, could they be feeling that they have limited options when they are around a barking dog? Is it possible that not being able to bark back causes anxiety/aggravation in this situation?

  • Is the Rat Terrier teaching her bad habits that she did not have before? I have found some JRTs/RTs at the dog parks to be very barky and so playful that sometimes they will not leave the other dogs alone-keep bothering them to play.

    Sparkle Barkle came into heat in April. Logan went nuts! I was traveling so my wife was saddled with the mayhem. Mayhem doesn't begin to describe the situation. Sparkle should be coming in again within days, I hope, and unfortunately, he won't get any love this time either. He's gonna be a massive handful for at least a MONTH. I'm not traveling this time, so it's all on me. Cross your fingers for Tri females. I want three!

    Basenjis' function in the wild is to go after small game. I expect mine to hunt (and kill if they catch them) squirrels and rabbits. Other dogs are a no-no ! Mine know I do not tolerate aggression to other dogs, regardless of their size. We are just back from a long walk in the forest where my two ran free and hunted (abortively, nothing caught) with a Cocker Spaniel. We met and chatted with lots of other dogs of all shapes and sizes and their owners . Humans stopped to chat, dogs did the normal meet, greet and sniff and there was not a single cross word. The only trainer mine have ever had is their own pack alpha - ME ! Do not let aggressive behaviour take hold. Nip it in the bud NOW.

    There are studies from 15 years ago about spaying at the wrong time during a cycle and ending up with a permanently aggressive female. But even with regular spay/neuters a great deal of hormonal change can cause many dogs to react. It is biological but still important to stay on top of behaviors so they don't become common. As for the fight...spayed, not spayed, neutered or not, it is not uncommon for dogs who have always been fine to have one fight and never get along again. There are some worrisome new research about reactive and fearful behaviors with neutered dogs. If anyone is interested, glad to share the links (too tired to fetch them tonight. Back to my normal backing up posts with links so that anyone wanting to read more can.)

    Working with Oakley..progress is slow but had promising results during our "boarder stay"…he instantly remember the dog who we had as a 8-12 week puppy...he had moments of snarkiness which are very typical for him, coming too Close when he's sleeping, after he's played for awhile..as far as the food goes it was better than expected. He seemed ok to eat in the kitchen with her as long as he ate first...the only troublesome moments were in anticipation of the meal as I was fixing their bowls, he would go after her and snark and bite but not viciously..it was stern, don't get me wrong but he seemed not to take it to the next level which he would have done with a dog he didn't know. The bigger issue was when "I" was eating..my food sparked definite territorialsm, he would get aggressive but still with a stop filter..he wouldn't allow her near me and she knew to backoff and stay alway. I did end up crating him during my meals when he got too stimulated. Overall, I was surprised to see he didn't viciously try to hurt her but he definitely displayed inappropriate behaviors (for what I'd want to see in the future). I'm pleased it was better than expected and have a better direction in training

    We have already started the positive reinforcement. My 12 year old daughter is very good with him, and she feeds him in the morning. He is always fed in his crate, and we always thought it was cute and funny that as we were putting the food in his dish he was crawling underneath us to get to it. That changed last night. When I was putting water in his dish I made him wait until I had finished. He was trying to drink it through the bars as I poured it. My hubby and daughter have both read the article I printed out. I think Paige will better follow it as my hubby is very softhearted and all our dogs run our life because he simply can't dominate them.
