A disabled dog should have a tag or a vest that showing that they they're disabled

 it's important to me because I'm totally allergic to dogs

When you bring a service dog into a store it should have a tag or vest on it to show it is a service dog and it should not be around the food hot food or cold food because the dog hair shed how is that in proper code with the health department if you have animals around you food also when the dog ride with their owner on the bus they should have a handicap tag or vest showing that disabled dogs or have papers if a disabled dog it should sit in the owner's lap not walking the aisle
