Ok, a while back, I started to get itchy at work after ripping up a carpet (I think was the cause, not sure). Then it got worst, and I was itchy all over for the most part, and it "seemed" to spread to my home living spaces, mostly carpeting, bedding, and couches, it seemed. We got one of those alergenic bed covers, and it seemed to help alot. The only reason I say carpet is because I picked up a big roll of this used carpet and my arms were all red and itchy, so I feel they are linked. So anyway, then my girlfriend then caught it, and she has rashes all over now too. The weird part is, my dog seems to have caught it (which seems nearly impossible to me) and now my little child has it. It looks like mosquito bites on me, but sometimes a bunch of little bumps. On my girlfriend it looks like small bumpy rashes, and on the baby, it looks like bug bites. On the dog, he has black spots like scabs. Does this sound like scabies or is it something else?
