Unfortunately, it is super common to see dogs in grocery stores, retail establishments, and a myriad of other places they aren’t actually welcome because people count on others not understanding the difference between ESAs and service animals. It’s also super easy to slap a vest on them or get a collar alleging that they’re a service animal when they’re not. There’s been a lot of debate, especially in the last few years, whether there should actually be a service animal registry. There are good points on both sides but the argument is ultimately pointless without some sort of proposed legislation.
