Three weeks ago I got Heidi a microchip. She seemed to take it well, but she keeps scratching at the place where they implanted it. The top of her shoulder is broke out in red bumps. You can still see the needle spot, but it doesn't look irritated itself. I don't know what to think. It started looking better, but now she has the surface scratched up again. What could be going on? Can't be allergic to it can she?
