Not sure if this is helps, but here's my suggestion, FWIW..if your dog is neurotic..give him a substitute obsession. I had a doxie once..great dog...sweet, loveable..got along well with everything..kids, cats, even the parrot..but the dog was nuts for a tennis ball..she'd fetch it, bring it back, and wait for you to throw it again...inside, outside, anywheres, incessantly... you know how they quiver when they're excited..attentive..like they just got a mild electric shock...I only stopped tossing the ball when my arm got tired...is your dog into fetching balls?..maybe you can substitute..get him hooked on the ball, then when he barks..roll the ball..he can't run and bark, and he can't bark with a tennis ball in his mouth..
