Good for you! I hope she won't mind me saying this but if you have any questions about training, Xena is the most effective dog trainer ever. Via email she has helped me sort a few difficulties my dog was having and I know many people she has helped. It is well worth hiring her for a session on basic training and teaching you how to be boss. In my opinion, if your dog knows you are the boss you will not encounter many of the problems having a teenage dog will give you, especially the issue of having visitors able to come to your home without the dog believing as top dog, he must deal with them. Good luck and bless you for taking a stray instead of looking for a "designer" breed, JJ
