Residual antibacterial activity of canine hair treated with topical antimicrobial sprays against Staphylococcus pseudintermedius in vitro.

Background: Topical antimicrobial therapy is increasingly important in the treatment of canine pyoderma as the incidence of multidrug resistance has risen. However, little information is reported on the persistence of activity of topical antimicrobial products.

Objective: To determine the residual antibacterial activity of canine hairs treated with antimicrobial sprays.
