This is a quote from the Canadian Agility Team website about elegablity; Emma is not CKC reg, but I am going to get her a Limited Regestration. Does this mean she is not elegable for worlds? Is Limited Reg, different than PEN? Although worlds are in Oct. and Emma will be old enough to compete, Im not going to put in an aplication. She will be old enough in August, so there is not way she'd be ready.
