Any physically sound dog may compete in the AWI World Championship Series, subject to the restrictions described below:

Due to the risk of injury because of underdeveloped anatomy, dogs must be at least one year old to be eligible to compete in the AWI World Championship Series Open Division. The AWI realizes that it is difficult to determine the age of some rescue dogs, and does not want to bar any dogs from competition. The AWI requests that handlers use their best judgment in entering dogs of uncertain age, not vault dogs under the age of eighteen months ( if so the AWI will disqualify the handler for lifetime from playing any AWI event), and above all BE SAFE.

Bitches in heat are allowed to play. Owners are advised to keep the their BIH away from the field if not playing and walk their BIH far from the competition area to relieve it, if possible.
All dogs must have current Rabies vaccinations. Vaccinations for Parvovirus and Kennel Cough are strongly recommended.
