Hi Tinks,

Barking collars and bark deterrents are a fantastic way to curb your dog's barking. The real trick is making sure you choose the right one for your dog. I have a little dog, so the spray collars have been fantastic for her - she is no longer the little yapper that drove me nuts.
My brother has a dalmatian, his dog just licked his lips every time the spray collar went off - it didn't stop his barking at all. The guys at Bark Control have been fantastic in helping both my brother and I (even though I sold him on the spray collar, they were happy to upgrade him). I have included one of their articles about bark collars, have a look at it when you get the chance. Might even be worth giving them a call... Good Luck
