UNFAIR ANIMAL RIGHTS IN ESTABLISHMENTS NATION WIDE

We were asked to leave a supermarket b/c we had our emotional support registered 10 lb puppy who was contained in a TSA carrier in the child seat of shopping cart. Police officer approached us (very intimidating) asking "what service does this animal perform" unaware of the FL state laws concerning animals in establishments...we said she was a registered emotional support animal keeps us calm from PTSS ...he said "finish your shopping and get out of the store." We see children sitting in the food part of shopping carts all the time with their Filthy shoes and clothes but that's ok???!!! I am not comparing Children to Animals but some of us treat our animals like kids and they are better behaved than some. I wd like this law in all states rewritten. PLEASE HELP! THANK YOU.
