I stopped him on the mat, used my hands to physically wipe his little paws on the mat, and just repeated “good wipe your feet” over and over while feeding him treats. He figured it out after like two five minute attempts. And if a stubborn-ass dachshund can do it, whatever breed you have can totally learn it.

We don’t even have to tell him to do it anymore… he comes in through the dog door from outside and we hear vigorous foot wiping on the mat til he gets his treat.
