I agree take her and get the shot she is way to young in the first place and like Donna said she needs all her tests done and she needs to be certified before she gets bred. So hopefully she isn't pregnant, but if she is go get her a shot from the vet.
Get the shot. She is to young, and take it from someone who has been there. Get her fixed. All I can say here is leave the breeding to the people who know what they are doing. When I got Dally she was pregant. She was only 9 months old. She miscarried. I was glad, once I found out the whole story. Like Donna said, hips, elbows and eyes all need to be CERT.
