In such an event, the wolf may try and eat some of the competition. Makes for an easier win.
The MinPins and Chihuahuas TRY but are not able to succeed as a general rule. They get DQed anyhow.
Thank goodness I always ran my dog in the 20" or 22" class (depending on the association) so I wouldn't have to deal with the nasty little yap dogs (in the 8" class or lower) or the wolves who would probably be in 24" or 26". At least according to the "International Wolf Center" - whoever they are!
