Side effects of a dog licking hydrocortisone cream can include vomiting or diarrhea due to stomach irritation, increased thirst and urination, and panting.
Generally, if your dog has consumed little amounts of hydrocortisone cream, and not the entire tube of cream, you may not need to consult your vet immediately. Keeping the dog hydrated in the aftermath of ingesting the cream, while monitoring for side effects, should have the pooch feeling better in a matter of hours.
However, after some days, if you notice additional reactions to ingesting hydrocortisone, such as a loss of appetite and lethargy, you should pick up the phone and book an appointment with a vet right away!
Even when not ingested, prolonged use of hydrocortisone on dogs can result in side effects such as flaky or fragile skin. You should also monitor a pooch that is being treated with hydrocortisone for advanced reactions such as hives, swelling or breathing difficulties. Do contact your vet immediately if you observe the manifestation of any of these symptoms.
