We have three dogs, two lab/mixes and a beagle/weeine dog mix (aka "the Weagle") and we love all three. All are rescue dogs. Our problem is with the Weagle. Whenever somebody, somebody with a dog, or just another dog goes by the house, or when we're taking a walk, she emits the loudest and most annoying shrill half bark/half squeal you've ever heard. We need to correct this behavior, that has just gotten worse, soon! Any suggestions for a safe bark collar that won't zap the poor critter?
