Seriously folks, if you have a rambunctious dog whom you hike and play with 3+ hours a day to drain her energy only to come home and still have a dog that is over stimulated by any stimulus in her urban setting, this is the solution for her and you!. After only a few days with this E-Collar on my dog (and instruction on how to use it correctly from a very knowledgeable dog trainer), my 2.5 year old Lab is learning very quickly to settle rather than bark her head off whenever anything or anyone passes by our house . The best part is that she responds to a low level “tap” from the E-Collar and she understands that one short bark works better than her frantic non-stop barking. She is also calmer in the house now and doesn’t seem so anxious anymore. I always though E-Collars were inhumaine, but they aren’t because if you use them correctly, they simply teach the dog a more appropriate way to behave and ultimately creates a calmer, happier dog who won’t be the bane of the neighbourhood.
