Why does my dog have red bumps on its body?
Expert Answer
Red bumps on a dog can be caused by allergies, eczema, parasite infection, bacterial infection, fungal infection, and other reasons. If you notice red bumps, put an Elizabethan collar on the dog promptly to prevent licking or scratching the area, and take it to a vet to identify the cause and treat it accordingly.
If the cause is a parasite infection, deworm the dog promptly and apply an anti-inflammatory spray to the affected area.
My dog broke out in red bumps and the article's list, allergies, mites, bacteria, fungus, covers it, I couldn't tell which so I didn't guess. E-collar on first to stop the licking, then vet to pin the cause, because the treatment differs by culprit. Mine was a mite, dewormed and an anti-inflammatory spray fixed it. If bumps spread or he's miserable, don't wait, get him seen, scratching opens the door to infection. The collar buys time but the diagnosis is what actually clears it, so get to a vet.
