Do you find it bad to use bark collar to eliminate the excessive barking behavior of your pet? I am planning to purchase a spray bark collar that I found online to get rid of the barking issues that my Pomeranian have since we moved into a new apartment. I have asked some of my friends and they told me that a citronella collar is better than using a shock collar one. What are your thoughts about it? Is there any other way aside from using this product?
