Title: It worked great...at first
Product review: This collar worked great when we first got it. Our dog would stop barking at the first spray. However, after about a week, she learned to just bark quickly to empty out the canister. The directions said not to let the canister empty out, but how do you keep it full if your dog runs outside, and barks her head off? You can't. It's not worth the money if you have to be outside trailing after your dog to refill the collar all day.
