she is still really young, and the classes are going to do wonders for her....Lady was scared to death of alot of dogs, when we first got her which was around 12 weeks. Even though she had been best friends with a Jack Russell at the breeders. She got so scared she even clawed up me and peed on me once. make sure when she is around other dogs, that she isn't feeding off any scared feelings from you, you want to be cool, calm and collected all the time. The classes will do wonders!!!
