I know they have 120 seconds max to go from bells to truck rolling, but average less than that. Plus a few minutes travel time. So from making the call to professionals arriving on scene (that are trained in ice rescue and can do it safely) in about 5 minutes.

I’d take the sure bet over the uncertainty of me being able to climb back onto the ice should I fall in.

On the other hand, you could just control your leashed dog and not put yourself in such a situation.
