Hello. My Shih Tzu boy normally doesn't need a bath in between his visits to the groomer. However, the dog walker today allowed him to go swimming in a lake (something that he has NEVER before shown an interest in doing!) and he smells terribly of damp sheep/mop. Would baby talc be okay as a one-off? Or should I just wait until the local independent dog shop reopens on Tuesday, and get him some proper dog dry shampoo? Thanks.
