Obedience competitions are based on a structured curriculum of testing for dogs with commands including heel, sit, stay, come, down, and stand. Dogs can win titles in obedience and many people find this a great way to teach their dog basic manners - a very good idea for the Puli!
Obedience has recently expanded to also include Rally competitions. Rally is presented as a less rigid introduction to obedience and has quickly gained popularity with entries often exceeding those of the traditional obedience trials.
Obedience is a great way to work with your dog and ensure that your Puli is a Canine Good Citizen.
