In editor spawn a dog:

MyDog = group player createUnit ["Fin_random_F",getposatl player,[],0,"NONE"]
MyDog setVariable ["BIS_fnc_animalBehaviour_disable", true];
MyDog setAnimSpeedCoef 4;

Notice how the animation speed of the dog is still the same as without using setAnimSpeedCoef.

Being able to use this command on animals, especially dogs would provide some more authentic gameplay, since as of now dogs can only achieve running speeds of around 23km/h, which is way too low.
