Is one day of prednisone for dog allergies safe for his organs?
Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry Bruno had hives and other skin irritation. Prednisone can have an effect on the body if given long-term or at high doses; typically, a short course of a steroid can have some short-lived side effects (increase in hunger/urination, eating/drinking more), but tends to be otherwise well-tolerated. While any medication can have an adverse effect (and if you are seeing any concerning signs I would reach out to your regular veterinarian immediately), low doses of appropriately dispensed steroids should be processed fine unless there is another underlying medical condition. Again, if you are concerned or if Bruno is showing signs of being ill, I would have him evaluated by a veterinarian as soon as possible.
