Kathy and David the owners of Dogwatch by Laughing Labrador are always quick to help us even finding and fixing a broken wire under snow in frozen ground. The training they did for our new addition helped her figure out her boundaries in just a few days. My neighbors with invisible fences are jealous of the 2 yr battery life our collars get while he’s spending about $ 80 a yr on batteries for each of his dogs. Dogwatch and laughing lab are #1.
