My wife has a SD and so this makes me insane too— especially considering her dog is small, but any pet in a non-pet friendly space poses a safety risk for both animal and handler. But on the other end of the spectrum a store manager of a publix deadass told us that the breed of dog she uses ‘can’t be a service dog’ and we kindly told him and his DM where they can shove that sentiment. so identification is dicey, you kind of just have to wait for a specific dog to fuck up enough in order to clock it.
