In order to disable dogs on your maps you must follow these steps.
 
1.-Go to raw/maps/... and find the zombie_mapname.gsc file and copy it to your mods/mapname/maps/.. folder.
 
2.-Open the file and look for this line:

level.dogs_enabled = true;

Change the variable to false

level.dogs_enabled = false;

In the same file look for this line:

maps\_zombiemode_ai_dogs::enable_dog_rounds();

Just comment the line like this:

//maps\_zombiemode_ai_dogs::enable_dog_rounds();

IMPORTANT NOTE. If you want to remove the dogs from your map do so, but don't remove the script_struct from the zone_test (your initial zone) where the dogs spawn as those are used by quickrevive.
