Query: citronella no bark collar

The collar was way too big for a miniature schnauzer. We did trim it following the directions and used it. When it worked it did make him stop barking but it had to be fussed with often. Refilling, retightening etc. It made him very wary and nervous when it worked. He learned quickly when it was on or off. Once he barked when my grandaughter was sitting by him and they both got sprayed no ill effects for either but a lot of complaining. It worked approximately 3 days. The 4 flashes light came on and won't go off. This indicates no fill. But even though I fill it ???? It won't work anymore. So I don't recommend this particular collar. It's way too much $$$ for 3 days of silence.
