“it’s unhealthy for them to be in a food store.”
Not really. Not if they are house dogs. Used to be a fairly common sight in England.
House dogs are just a bad a dog is a filthy inside or out side they have worms the brown marks on your floor is from it dragging it’s ass across it.
They need to be banned form any store especially food stores there is not a reason they need to be allowed in one.
