    A word of warning if you are choosing a dog for emotional support, or as a future psychiatric service dog! I am an Accredited Dog Trainer through the International Association of Animal Behavior Consultants, and I work with Service Dogs.
    Certain breed groups, particularly Herding breeds, and other dogs selected for their attentiveness to humans, can mirror your stress. Just as long-term stress is damaging for human health, chronic stress is detrimental to some dogs' wellbeing. (Conversely, some breeds really couldn't give a crap whether you're having a bad day.)
    Additionally, when raising puppies for this kind of work, the adolescent dog needs a secure attachment to their owner. Having a supportive, predictable relationship with their primary caregiver during this phase of development has a big effect on the dog's adult behavior. It's tough enough to raise a puppy for healthy people, let alone someone who is struggling with their health, be it physical or mental.
    Please reach out to a certified trainer before you bring home a puppy if you are a first-time dog owner. It takes a village to raise a puppy!

    The dog study makes sense with my experience. My best friend has a corgi who sees me regularly and seems to consider me one of "her humans". I have PTSD, and can easily spike my stress just by thinking about one of my triggers. Every time I do that in the same room as the dog, I end up with a lapful of corgi within a minute or so. She won't leave until I calm down or someone orders her away. We joke about her being my self-appointed therapy dog.
    I'd be interested to see if cats have a similar mechanism, too. My neighbor's cat (whom I cat-sit pretty regularly) has also consistently reacted to sudden changes in my stress level, either by sitting unusually close to me or, in one notable case, trying to threaten the stimulus that had triggered me. Unfortunately, it was a noise from next door, so he ended up trying to intimidate a wall, but it was still impressive. 😂

      Cats are actually somewhere around 10x as sensitive to smell as dogs are, iirc. They definitely can detect it, and I think how they respond to it depends on the personality of the cat. My dog never cared if I was in stress or not, but my cat is extremely prone to it. Just depends on the animal.

      It wouldn’t surprise me, re cats. It likely depends on how well they’ve been socialized; people have some strange ideas about cats that aren’t entirely accurate, so many cats are kind of, well, clinically crazy. But if you have one that hasn’t been harmed, yeah. They can really firmly bond to people and do their best to provide protection and care, and there’s some decent evidence that suggests they see us as part of their clowder, and often members that need special care.

      Some dogs don't particularly like stress, it's an odd thing. When people get a bit stressed or angered my dog often leaves to go somewhere else (after my grandma passed and we lost her dog as well they started putting the family dog in with me to keep me company, she hated being in their likely because I stunk of stress and depression which she doesn't particularly like..she'd literally sit against my door as far away from me as she could get, clearly not wanting to be in with me, but after a while she got more used to it and now she doesn't mind being in here with me), though she tends to have the more "hide" reaction if the one upset is male, no idea why but dudes kinda intimidate her

    I have a service dog. He wasn't chosen for anything specific other than preferred breed(s), which is a pit bull mix. He is also rottweiler. He checks my blood sugar by licking my hands. He also alerts me to panic attacks (which low sugar can cause for me). He is quick to respond to the stress of anyone around him, especially my husband. All 3 of my dogs respond to our stress, the others being a retired service dog and a neurotic emotional support animal who needs her own emotional support human. My cats respond as well.

    I really do believe that the pandemic really changed my personality. Before, I was super extroverted, open, and I liked talking to people in general. Now, I don’t trust anyone, my health and social anxiety have skyrocketed, I’m more angry, more on-edge and more paranoid than before. I know these traits can just be that; traits. But I feel like my personhood itself has shifted from someone on the extroverted scale, then the ambivert scale in the start of the pandemic, then to completely introverted, and now, I’m trying to find an equilibrium. I also developed moderate tinnitus and TMJ issues bc of stress from the pandemic, so stress also just a part of my normal life, and I feel like a lot of people can relate to that.

      Hey Jen, do you have back pain or joint pain too? Any issues with short term memory? Any nerve twitches? Did you do more hiking during the pandemic? Only asking because there are 17 tick-borne diseases and one causes tinnitus and TMJ. Lyme causes personality problems exactly like you describe. I know because I had them. Juvenile ticks are basically invisible because they are so little. Less than half of Lyme patients ever get that telltale bullet rash. Only the Western Blot test read by a Lyme disease specialist will be able to diagnose tick-borne disease. It took IV antibiotics to finally knock out Lyme disease in me but I’m pain free, finally feel rested when I wake up in the morning and best of all my memory and personality are back!! Five days on antibiotics and my depression lifted. I didn’t even realize how depressed I’d been until that wonderous day that I could feel joy again!

Maybe he could tell based on cue, but when he switched the dog instantly left the room because one personality that was really strict didn’t like the dog in the living room because of the hair. The dog approached the couch and his tail was wagging but when he switched the door sat outside the room and looked at him.

      The sweat you give off from stress is different from sweat you give off from heat. Instead it's oily, usually from the armpits and groin. It's also produced during exercise and sex. Bacteria are fond of the oily fatty stuff in that sweat and it makes you stinky.
      Apparently East Asian people don't get sweat like that and therefore don't have body odor.

    I have a wonderful service dog who tasks for both for an anxiety-related disability as well as heart problems. It’s incredible what he can do. He knows my heart rate is about to drop very low a few minutes before it even happens. I’d love to see studies on what VOC’s, small movements, etc he could be picking up on. Even in a lab with the smell of chemicals around he can give me that “something’s up” stare before I even feel it. I know diabetic alert dogs have been studied, but as far as I know there hasn’t been very conclusive research in what other types of alert dogs are picking up on. One of the many reasons why I’m studying to work in veterinary research!

    Those "pandemic personality" results are kinda surprising- in my (admittedly extremely limited) experience, all the _older_ people I've interacted with since the pandemic started have been the ones to become more neurotic, irritable, and argumentative, while broadly speaking the younger ones are generally level-headed.

  • @fghsgh
    @fghsgh ปีที่แล้ว +21

    I know for sure my personality has changed during the pandemic, but actually, it appears my "positive" qualities have generally increased. I am better at talking to people, at managing my emotions, at discussing sensitive topics, I have seen a noticeable increase in my empathy (which, given my starting point was pretty much "none at all", way definitely very noticeable), and have naturally started being more respectful towards people. And people have also noticed these (and complimented me on them, which is how I know). The only thing that has gotten worse is my social anxiety.
    All of these can, I suspect, be attributed to the fact that I became active in several chatrooms of generally nice people. Which was finally a method of communication that felt _natural_ to me and didn't cause me constant anxiety.

    • @iprobablyforgotsomething
      @iprobablyforgotsomething ปีที่แล้ว +3

      Face-to-face socializing (even positive experiences) is extemely draining for some people, such as introverts. The enforced break from that because of the pandemic gave a lot of people a chance to recovery from being burned out on social engagements. And so they might then enjoy and appreciate the now-rarer chances to interact in person. Or do better when interacting in other ways, such as online, as you mentioned.
      .
      It's easier to have a positive attitude, and be more gracious and forgiving in general, when one isn't so stressed and socially jet-lagged that they're effectively going through each day with the energy level and enthusiasm of a person who's suffering from the flu and chronic migraines simultaneously.

Attempting to make eye contact with me..she will even paw me until I can/do! She also if that doesnt settle me, will lean right into me (if I am getting angry and swearing, which I now know is the pinnacle of my anxiety). She pushes so hard and I have to acknowledge her, which makes me breath (generally ) and stop swearing and my anger dissipates relatively quickly.
