Quote on the back opposing the sue of shock collars on dogs that reads: “I oppose the use of shock collars, prong collars, and choke collars… Such tools ‘work’ by engendering fear, pain, and distrust, and in doing so they cause long-term damage that make dogs more reactive, less trusting, and less able to reach their full potential in their partnership with humans. These are not my opinions: these are the findings from the scientific literature.” - Dr. Karen Overall, MA, VMD, PhD, DACVB, ABS Certified Applied Animal Behaviorist"
