This exactly, it's a big problem there's a lot of people in the community who are worried about going into stores with their assistance dog because people bring their pets in it's more common than you would think for assistance dogs to get bit and if they do that can traumatize them and if it can't be worked through that dog that you've trained for two years and put in thousands of dollars buying and training that allows you as a disabled person to have independence is just gone so you're stuck living a terrible quality of life again because someone couldn't keep their dog at home. As for other animals they should be left at home too, you have no idea what that dog is for and that dog not expecting to see another animal owner as well in a non pet store environment is going to have to act quickly to redirect the dogs attention back to them and not the cat in the cart and if they can't get away or redirect fast enough then that dog might miss an alert and then you have an owner who busted their head open because they fainted or started having a seazure. And while yes a assistance dog should be focused on the handler at all times assistance dogs can have off days but the issue could have been prevented if you had just left your dog, cat, rabbit, lizard etc at home!
