Our beautiful puppy is now almost 15 weeks old. We had her since 8 weeks and I can not believe how fast she has grown! She is very smart and easy going dog. We have so far taught her the following commands: pee when we are outside, come, sit, down. The next one I plan to teach is drop (I suspect this will be a difficult one!). She has learned sit and down very easily, within me telling her 3 to 4 times. What other important commands should be taught? Also, what age do they start getting to old to learn new commands?
