Anxiety or Allergic Reaction?

We have recently gotten a dog Blue Heeler (Australian Sheepdog) x German Shepherd and since I am unemployed I take care of the dog to occupy my time. For the first week I was fine, but as the week went on I've been feeling worse, I've had brainfog, nausea, dizziness, chronic fatigue, shooting pains in my face. I saw my doctor because I was concerned that I had a sinus infection because the edges near my eye were darkening, he examined my throat and checked for any irregularities in my breathing or my heartbeat. He found nothing.

I'm worried that he may have missed something, because I am worried that constant exposure to my dog would cause a sinus infection and in some cases, A.D.D or brain damage.

So, could anybody shed some light on the situation? Can allergies cause A.D.D?

Hi True. Pets have a lot of dander and can cause many allergic reactions. Try washing your dog more to see if it clears up.

Anxiety can cause all sorts of symptoms.  Have you been expereincing stress and anxiety for a while now.  In my experience, anxiety can definitely ebb and flow over periods of time.

Perhaps the fact my dog is untrained and causing me stress?
