what could cause an allergic reaction that makes me break out with a rash? It i on my shoulders, chest, neck, face (a little), and spreading to my shouder blades, stomach and arms. The rash slowly becomes raised whelp like marks and bumps. The only thing i can think of is i am allergic to my puppy i got a few days ago but i have several other dogs in which i am not allergic to. I have no clue what this could be from...
Please help!!
