I use the old mouthed Bark woof woof sometimes. also been using a ( squeaker bulb ) that I robed from inside a old dogs chew toy . 'squeaker' I put it inside a little pouch I made, that is on a lanyard to my belt. Squeaker sits in my L-front pant packet for a dozen+ years . A squeaker Bulb is pretty loud at nighttime.
When I on the gun, All I do is just reach down with left hand and give it a tap. It really works great to get a dog to stop and pose. If I want a dog to hear it that is a couple hundred yards out, I just pull squeaker out of my pocket and give a couple hard loud squeezes.
