Hello all! I will be getting a puppy maybe around next month, but I have a concern when it comes to training. I currently own a 6 year old female german shepherd (Lucky), and she is a darling, but never had the proper training. She has a few bad habits, but nothing to crazy. For example, when I enter the house after being gone for long hours she'll repeatedly jump on me for a while (which I don’t mind, but can be frustrating especially if I’m carrying stuff in or just not feeling well). Another example is when I take her for walks, I go for jogs every morning in this field like area and she runs along with me loose, but to get to this area, I have to walk her there with a leash and she has the tendency to pull sometimes, but nothing too bad that I can’t handle. Not only that, she gets very excited when seeing another dog, at the point where she pulls me when she's on the leash, but again, it’s nothing that I can’t handle. She understands basic commands such as sit, or out, in, come here and so on. She just has these bad habits. Now here’s the thing, I want to add an addition to the family, but unlike Lucky, I want this puppy to have the proper training. I want to take him to training classes. I just worry that these classes would be pointless if he see’s Lucky jumping on me, pulling on the leash at times when on walks, and getting overly excited. I’m afraid that he would mimic her, any ideas?
