OBJECTIVES: To assess efficacy of a gel compound containing guar, glycerine, triclosan and ethanol (Pawcare®, JOKER Technologies, Kerzers, Switzerland) in decreasing bacterial and yeast loads on the paws of dogs with erythematous, greasy and/or malodorous pododermatitis. METHODS: In 20 dogs, each with at least two affected paws, semiquantitative Malassezia species counts were performed on 10 oil‐immersion fields (range: 0 to 30) from acetate tapes pressed on the palmar/plantar surface of one paw. Half of the area was sampled before and the other half immediately after the application of Pawcare®. With a similar procedure, swab samples were collected from the other paw for bacterial culture, identification and evaluation of colony‐forming units before and immediately after treatment. Statistical evaluation of pre‐ and posttreatment counts was performed with the Wilcoxon signed‐rank test. RESULTS: Nine dogs were positive for Malassezia species Mean acetate tape preparation counts decreased significantly from 8·78 (±8·03) to 5·668 (±6·65) (P=0·0039) after treatment. Twenty‐five bacterial isolates of 11 different species were cultured in 19 dogs. Posttreatment cultures were sterile in 8 dogs that had an initial zero or low number (1 to 2 log counts) of colony‐forming units. In cases with a higher pre‐treatment number of colony forming units (2 to 6 log counts), there was a significant decrease – by a mean of 1·16 log counts (pre 3·12 ±1·69, post 1·96 ±1·57) (P=0·0002). CLINICAL SIGNIFICANCE: The findings of the present study support the use of PawCare ® gel to decrease bacterial and yeast loads in dogs affected by chronic diseases involving the inter‐digital spaces.
