Baypath Humane Society supports humane training methods that are based on redirection and positive reinforcement to shape desired behaviors in companion animals. Methods of rewards such as food, praise, petting, and play that are based on a mutual understanding, kindness, and respect between the pet and the guardian have proven to be successful in managing behavior. Baypath Humane Society opposes any methods, training tools, or aids that cause physical harm or discomfort to an animal.
The American Society for the Prevention of Cruelty to Animals (ASPCA) has some great information on training aid and methods. Please see their Position Statement on Training Aids and Methods.
For more in depth information on the science behind this methodology, please see the American Veterinary Society of Animal Behavior's Position Statement on The Use of Punishment for Behavior Modification in Animals and Position Statement on Dominance Theory.
