Training shouldn't involve pain or intimidatioN for you or your pet

The science is clear: Smoking causes cancer. Greenhouse gas emissions exacerbate climate change. And animal training techniques based on pain and intimidation can create dangerous, suffering pets that may lash out at those around them, often at the worst possible times. 


While scholarly research and their own ineptitude have discredited "celebrity" proponents of the sadistic approach to pet training, it's still common to see people advertising their ability to "teach your pet it's place in the pack" or "get quick results through a balanced approach." This pseudo-scientific jargon can sound reasonable, but all too often it simply translates into bullying and frightening your pet; using pain aversion techniques including choke, prong, and shock collars (which you may be pressured to purchase); and even inflicting physical violence. 


Like most quick fixes, it doesn't work in the long run and often creates additional, more difficult issues. More importantly, it's just wrong. Your pet is capable of feeling as much pain, fear, and frustration as you are. The bottom line is that only humane, science-based training grounded in positive reinforcement and a respect for the rights and well-being of our animal companions is effective long-term. 


You and your pet deserve nothing less. No matter where you turn for help with your pet questions and concerns, please be sure that the people you trust with your pet's welfare are familiar with the emerging science of animal behavior and that they are committed to doing what's right.
