Shadow chasing OCD

Hi everyone.

I’m asking for help because I’m at my wits' end with Vaïa, who is 18 months old. She has been chasing shadows since she was 4 months old. We are talking about a real addiction that makes her completely unresponsive to any other activity during these times. Out on a patio, the sunlight affects her so much it's as if she's ill; she no longer responds to her name, and won't play, eat, or even drink. We have obviously seen a veterinary behaviourist, but they had never seen this behaviour before. We then consulted another vet who suspected epilepsy, so we tried a course of treatment, but it didn't work and we didn't take it any further.

She is currently taking fluoxetine, but the behaviour has never stopped. To answer your questions in advance, Vaïa is a dog who gets out every day, plays, and has things to chew on, but to be honest, even after a long hike, once we get to the hut at the top, she still manages to focus on shadows and just switches off from the world.

We were living with it and trying to limit the triggers, but this weekend, my partner was visiting family with her, and after spending three or four hours under the table violently pawing at shadows, she attacked the family Chihuahua for no reason. Yet, she is such a kind and affectionate dog, who is usually quite submissive with other dogs.

We are thinking of seeing a veterinary neurologist to further investigate the possibility of a neurological issue. We are at a loss; we love her with all our hearts and we can tell she isn't right during these episodes, which can last the whole day, during which she won't eat or even go to the toilet. Have any of you seen a similar case? Do you have any ideas? Thanks in advance for any help.

    Hi there,
    Your message is really moving; it’s clear how dedicated you are to Vaïa and just how tough this situation is.

    You’ve already done so much (vet, behaviourist, treatment), so you’re definitely on the right track. Seeing a neurological vet sounds like a very good idea to definitively rule out a neurological cause (focal epilepsy or similar), especially given the intensity of the seizures.

    The incident with the Chihuahua might be down to a build-up of frustration or being completely overwhelmed during those moments, which could explain such an unusual reaction.

    Best of luck to you,

    Maëlla

    I think you need to find a behaviourist and a vet who are familiar with this type of disorder. It can be quite common in certain breeds, but the longer it goes uncorrected, the harder it will be to break the habit. And it could take several months of consistent work. You absolutely have to be strict with yourselves and not let her chase shadows (and I don't mean being aggressive with her, obviously! ^^). Your partner made a massive blunder by letting her get worked up for several hours, getting frustrated over something she can't catch and then taking it out on the little dog. I don't think it's a neurological issue because it's "just a bad habit that’s set in" and been reinforced to the point of becoming an addiction. In a hunting session (even with a ball—some dogs become addicted to those, too), the dog chases its prey and produces dopamine (the pleasure hormone), and the act of catching it calms them down (with a hormone I can't quite remember). The problem with a shadow is that it's never caught; the dopamine gives her the pleasure of the hunt (staring, catching...), but frustration builds up and spikes her cortisol (the stress hormone). So the dog is trying to reward herself by hunting prey but becomes neurotic because she can't catch it. You can give her medication, but it will never go away unless you do the necessary work to break the addiction for good. At this stage, you can't just try to limit these episodes; you have to stop them entirely, even if it means keeping the shutters closed all day. There are UV masks for dogs; by completely blocking her vision, it might break her shadow-hunting sequences. I know it sounds extreme—it’s like your dog going blind—but it might be an option. That said, I'm not a behaviourist or qualified in this kind of disorder, so don't take my word as gospel ^^’
