the link at post 24 provides a lot more info. The puppy isn’t a service dog yet, and was being trained so it probably didn’t look right to them. (But he did have the vest on. The buffoon manager should have given the Vet the benefit of the doubt.
Perhaps they train dogs differently in Texas, but here in PA, the dogs are provided by organizations that hand pick and train dogs to be placed.
When a dog is placed, the handler accompanies the disabled person and dog for public training sessions.
Also, 7 months is younger than normal here for placing a dog.
As for taking the pup on an escalator, that seems to me to be something I wouldn’t recommend doing so early in training.
Like I said, the article at post # 24 raises several questions in my mind.
