Once in motion getting them to do the exact opposite can be near impossible.
I find it very useful to teach a 'steady' command, and also 'walk on'
If I have been to slow with a recall command and the dog is/are already moving in the direction of the distraction, a command of steady will at least slow them down,a nd allow me time to catch up and then use the walk on command to keep them moving.
How I train steady is in all sorts of circumstances when they are pulling up or down steps, trying to push past through a door , or heading toward me to quickly.
The walk on is quite easy as if they don't you catch up with them and can give them a light slap stern word what have you and push them on past using their collar.
The instant down can also stop a dog in its tracks. You train the dog that going down quickly on command is a great game, and they will get a huge fuss. I have seen it trained almost like musical chairs where you get the dog to go down faster than you do.
Shouting down just might stop the dog in it's tracks.
With any of these commands you need to back the command up with your presence or the recall as soon as their attention is back with you for a split second.
