these bumps usually dry up after a few days they look worse than they are and are probably a reaction to something,stress is also a massive factor with these dogs though most of them look and act fine i think underneath they are nervy and insecure and very needy so any slight change causes stress which in turn can throw the immune system which in turn throws up the hotspots,hives and allergy symptoms ,dont forget that if antibiotics are given orally then follow up with acidophilus for a couple of weeks to help the gut recover from the antibiotics,karen
