crime dog i have never tried using a dog wistle but i think the howl will do the same thing(waking them up). even though fawns arent droping right now, if deer is their main food group. try it. i have had sucess with it at all times of the year. i like it in places where coyotes are called alot because its a sound they havnt herd a hunter use and they still come in as for if you used a rabbit distress they would hightail it out of there. most primos calls for distress purposes and desent open read calls for the price you pay. they can sound like all kinds of animals. ex. jackrabbit, cottentail fawn, doe,mouse, etc
