Summary

Methicillin‑resistant Staphylococcus pseudintermedius (MRSP), is a bacterial skin infection in pets, most commonly dogs. The bacterium normally lives on canine skin without causing disease, but in some animals it leads to difficult‑to‑treat skin infections that do not respond to common antibiotics. MRSP is most often seen in pets with recurrent skin infections related to underlying problems such as allergies or endocrine disease. Transmission to humans is rare, but good hygiene—especially frequent handwashing—is recommended. Treatment typically involves carefully prescribed oral antibiotics and aggressive topical therapies, along with addressing the underlying condition to reduce the risk of recurrence.
