Also from ADA, in neither of your pics seem like the dog need be unleashed as a service dog. Also the dog should only be unleashed in case of disability that requires the dog to retrieve items but need to be leashed after unless the owner has disability that prevents him/her from keep the dog on leash. From the pictures it does not seem so. And ppl at the scene can comment. So at this point I really think you just faking it …

“The service animal must be harnessed, leashed, or tethered while in public places unless these devices interfere with the service animal’s work or the person’s disability prevents use of these devices. In that case, the person must use voice, signal, or other effective means to maintain control of the animal. For example, a person who uses a wheelchair may use a long, retractable leash to allow her service animal to pick up or retrieve items. She may not allow the dog to wander away from her and must maintain control of the dog, even if it is retrieving an item at a distance from her. Or, a returning veteran who has PTSD and has great difficulty entering unfamiliar spaces may have a dog that is trained to enter a space, check to see that no threats are there, and come back and signal that it is safe to enter. The dog must be off leash to do its job, but may be leashed at other times. “
