I personally use a Johny Stewart Electronic caller but, mine is an older model. They make them a liitle more compact now.

I use a Primo rabbit sqawler from my mouth blown call.

Most of the calls out there are pretty good. Go with a reputable brand like Primo or Lohman. Pick up one of the instructional videos and practice with the mouth calls before going into the field. If the family dog runs into the other room and hides you're probably doing it wrong.

If he comes running along with every other dog within ear shot your good to go
