Hi. We used to live in Mesa, and boy did we have scorpions! We had the bark scorpions which are one of the worst kinds of scorpions. I would ask my vet before a possible sting what he would recommend you do if your dog got stung. We now live in NM where we also have scorpions, but they are not poisonous. Joe, my Boxer got stung in the mouth and paw just last week. He limped for about the first 5 steps he took and that was it. I say it's better to be prepared!
