Hi Kristin-Rashes can be caused by anything, and seem to be more common place in the summer time. The fact that she has a rash and a hotspot would make me use the antibiotics in a heart beat. Hot spots can literally grow into weeping nasty messes in a matter of hours-Antibiotics will help alleviate that, and often a gentamycin spray is also recc for topical use. I have never had hotspots on any of my dogs-with that said, someone gave me two bags of iams fish-the higher line of the Iams. I figures what could it hurt? So, I fed it mixed with the raw for two days. On day number three one dog had a weeping hot spot on his neck, and 24 hrs later the hair had fallen out. Off to the vet. I literally walked in the door to see another dog come running over with a freaking hot spot in the middle of his back, that had no been there 1 hr before when we left for the vet with dog 1.
