Dog Distracted Guide Dog

I ran into a tricky situation today. I was walking with Sterling, and as we came to an intersection, there was already a guide team waiting there. As soon as the guide saw Sterling, he started jumping up and down and became VERY distracted. The handler gave him corrections, but the dog continued to focus on Sterling. I called out that I had a dog and backed up several feet (I was already 10 ft away!) to give them space to work it out. When it came time for them to cross, the handler told the dog forward, and the dog almost ran him into a car that was blocking the cross walk (stopped car).

The dog also ran his head into a pedestrian that was passing by the team. I followed behind them...unfortunalty this is the way I had to go...and the dog kept spinning around to look at Sterling. When we got to the crub, the team stopped, and I called out my position as I passed behind them.

I am wondering if I should call the school so that the handler can get some help reworking with his dog? I would say maybe they were having a bad day...but one other time we ran into this team, the guide ran the handler into a railing looking back a Sterling.

What would you do....any suggestions? Also, was what I did in the situation correct, anything that would have been more helpful? I did make sure Sterling did not stare at the other dog, nor did bark or anything like that....
