Our verdict
Pet MD's Hydrocortisone Spray is a topical, spray-on treatment for hot spots and irritated skin with clear usage guardrails, and its 4.3 star average across more than 16,000 reviews makes it one of the more proven topical sprays in this category.
Dogs, cats, or horses with topical inflammation, dry itchy skin, or hot spots that need a direct spray-on treatment rather than an oral supplement.
Skip if
The affected area shows signs of infection or pus, since the label specifically says not to use it in those cases, or if symptoms haven't improved after 7 to 10 days, both signals to see a vet instead.

Performance notes
Hydrocortisone sprays like this work by reducing local inflammation and itching at the site of application, which is why the label limits use to two or three times daily and caps expected results within a 7 to 10 day window before recommending a vet visit. That kind of built-in timeline is useful for gauging whether a hot spot is resolving normally or needs professional attention.
What buyers say
With over 16,000 reviews at a 4.3 star average and roughly 9,000 bought last month, this spray has one of the stronger, higher-volume track records among topical itch and hot spot treatments in this roundup.
The label directs spraying the affected area no more than two to three times daily, or as directed by a veterinarian.
When should I stop using it and call the vet?
The label says to discontinue use and consult a vet if redness, irritation, or swelling persists, or if the condition hasn't improved after 7 to 10 days.
Can I use this on an open wound or infected area?
No. The directions specifically say not to use it where infection or pus is present.
